The Eiffel Tower in Paris Comparison Diagram Sample

The diagrams below give information about the Eiffel Tower in Paris and an outline project to extend it underground.

Complete Report

The diagram shows the future planning of the five-level underground project for the Eiffel Tower in Paris. The trend in this diagram is the development of this site and its current location.

As demonstrated, all five underground levels will be constructed with a glass ceiling. The first level will be used as the entrance to the main tower. Ticket offices are also situated on this same level. Next, shops and restaurants can be found on the second level. Speaking of the third level, it is planned to have a cinema and museums, while the fourth and fifth levels will be for parking.

As stated in the information box, the height of the second platform is slightly more than double the height of the first platform with 115m and 57m accordingly. The overall height of the structure is 324 m, and the tower weighs 10,100 tonnes.

To conclude, this diagram shows a planned project for the Eiffel Tower, along with some further details on the location and structure of the tower.

Flooding Comparison Diagram Sample

The diagrams below show how houses can be protected in areas that are prone to flooding.

Complete Report

The diagram illustrates the floodplain management to protect buildings from flooding in flood-prone areas with two protective methods. The trend suggests that two options for flood management are given, one with a stopbank and one without a stopbank.

The first diagram shows the option with a stopbank. This type of flooding occurs when runoff from heavy or widespread rainfall raises the water level and as it continues to rise, the berm angel of the stopbank holds back the rising water. It is constructed above the 100-year high watermark for consistent control at the highest levels ever recorded. A floodgate has also been constructed at the bottom of the stopbank so excess water can be drained from the internal ponding area, with the building being built on stilts to allow for the flow of water under it.

The second diagram shows the option where there is no stopbank. For this diagram, the 100-year water level is considered into the construction level of the building’s stilts, being just a bit higher than this level to protect against flood damage. No berm or floodgate has been constructed. The freeboard is 300mm higher than the 100-year flood level, and the building itself is raised a bit more compared to the diagram with a stopbank.

In conclusion, two floodplain management diagrams have been shown, one with a stopbank, and one where no stopbank has been made.

Generating Electricity Comparison Diagram Sample

The diagrams show a structure that is used to generate electricity from wave power.

Complete Report

The two diagrams show how electricity can be generated from the rise and fall of water caused by sea waves. The trend suggests that the process involves a structure which is mounted on the side of the sea wall, consisting of a large chamber with one end opening to the sea, and the other leading into a vertical column. A turbine has been installed inside this column, and it is used to generate the electricity in both stages. The first diagram, which has been labelled as A, shows that when a wave approaches the device, water is forced into the chamber, applying pressure on the air inside the column. This same air then escapes into the atmosphere through the turbine, which results in the production of electricity. The second diagram, which has been labelled as B, illustrates the next part of the process when the wave retreats. As the water level falls, the air from outside the column is sucked back in through the turbine. As a result, electricity continues to be generated. The turbine rotates in only one direction, regardless of the direction of the airflow. Overall, it can be seen that this structure is useful as electricity is generated in both processes, whether or not, the water is entering or retreating.

Floor Plan Comparison Diagram Sample

The diagrams below show the existing first-floor plan of a townhouse and a proposed plan for some remodelling work.

Complete Report

The two diagrams compare a townhouse floor plan before and after the construction of a few proposed changes. The trend suggests that some of these changes are being planned for the existing structure of the building. According to the plan, the hallway will be removed, and the position and shape of the staircase will also be changed.

In the first diagram, there are two entrance doors to the building. The one entrance door opens from the south of the house, and it leads into an entrance hall with stairs just to the right side. There is a small storage area under the stairs. At the end of the hallway, there are two internal doors, one on each side of it. The left door opens onto the living room while the side door opens onto the kitchen. On the opposite side of the kitchen's door, there is another door that allows for access from the northwest side of the house.

The second diagram shows that the wall between the hallway and the living room is planned to be knocked down to create a spacious open plan living space. Additionally, the staircase will be moved to the left side of the building, and the access to the kitchen will be accessed by a double door near the front entrance. The new staircase will be an inverted L shape and kitchen countertops will be installed throughout the kitchen area, along with its walls.

Overall, the diagram shows some significant changes that are proposed for this townhouse.

School Site Comparison Diagram Map Sample

The diagrams below show the site of a school in 2004 and the plan for changes to the school site in 2024.

Complete Report

The two pictures compare the layout of a school, as it was in the year 2004, with a proposed site design for the year 2024. It is clear that the main change for 2024 involves the addition of a new school building. The school will then be able to accommodate a considerably larger number of students.

In 2004, there are two school buildings with 600 students. These two builds were separated by a path. The parking lot is in the northwestern corner of the campus, with a main entrance to the school building just off from the parking area. A road to the parking area leads from the southwestern part of the campus, passing along a wooded area with many trees. A large sports field is located to the east of the school buildings, and 20 years later it no longer there.

In 2024, the student population has risen by 400 students, to a total of 1000, and the biggest planned difference can be seen with the addition of a third school building. This newly planned building will be situated where the sports field was 20 years prior. School building 3 is now the largest of all three school buildings. School buildings 1 and 2 will be connected and the path will be reduced in size. There will also be a planned road that will lead to a second parking area again where the sports field was 20 years before. This new road cuts in front of school building 2. The sports field is now much smaller, and it will be moved further south to an area beyond the newly constructed car park.

Overall, the changes that will happen to this school site 20 years later mostly involve the construction of a new school building and a second parking lot.

Skeletal Remains Comparison Diagram Sample

The diagrams show the skeletal systems of two ancestors of modern human beings.

Complete Report

The diagram shows the variations in the skeletal systems of two early types of humans. The trend suggests that Australopithecus afarensis had a heavier body and much longer arms, while Homo erectus was slimmer and had more developed joints.

To begin with, the upper half of the body on Australopithecus Afarensis had a much broader chest and waist than Homo Erectus, giving it a rounder appearance. The former had much longer arms and larger hands compared to the later skeletal remains which would have been better for tree climbing.

As for the lower half of the body, it can be seen that Homo Erectus had proportionately longer legs and larger hips, knees, and ankle joints. The feet of Homo Erectus were also smaller and more arched, with shorter toes. These differences meant that Homo Erectus was better suited to long-distance running. Significant changes can be seen in the development of early humans from this diagram. Homo Erectus is more similar to contemporary human beings with their long legs and arched feet. The physical variations are clearly related to differences in evolutionary traits.

Overall, there are significant differences in these two skeletal remains.

El Niño Comparison Diagram Sample

El Niño is the name of a warm ocean current the affects weather patterns on both sides of the Pacific Ocean. The diagrams compare normal conditions in the Pacific with El Niño conditions.

Complete Report

The diagram shows the weather patterns for normal conditions and El Niño conditions in the Pacific Ocean. The trend suggests that there are significant differences between these two conditions. In addition, El Niño causes some negative effects, such as climate change and seawater quality, while the normal conditions do not. Both diagrams have differences in trade winds and the routing of warm water. While the normal conditions have stronger trade winds in East Pacific compared to the West Pacific, the El Niño conditions create the exact opposite conditions. Also, the flow of warm water goes from the East to West Pacific normally, but during El Niño conditions are totally contrary. Additionally, a quantity of rain in usual conditions appears to the West, but it changes going to East when El Niño occurs. There are at least three effects that are caused by El Niño. In normal conditions, Australia has a rainy season that leads to the cultivation of plants and the source of cool seawater increases. Normal weather conditions create a lot of nutritious water, and more sunshine is brought to sea life in Peru. In contrast, El Niño causes droughts in Australia, declining cool water and rain in Peru, and a lower fish population. Overall, the conditions of these two weather patterns are quite different, and in many cases, that exact opposite of each other.

Camera Comparison Diagram Sample

The diagrams below show stages in the development of the camera since its invention in 1839.

Complete Report

The pictures illustrate how the camera developed since it was invented in 1839 until the year 2000. The trend suggests that four different models are shown over a period of slightly more than 160 years. The four cameras progressively become smaller with more options, based on the year they are made. The white camera made in 2000 is the smallest and it is the only digital camera. This camera is significantly smaller than the model from 1839. The earlier one is made of wood and is 36 cm long and consisted of three box-shaped sections. The latter camera is almost three times smaller and it is made of plastic. The earlier camera also has fewer features compared to the 2000 model. One of the biggest differences is the lenses. The 1839 camera has one made of brass, while the 2000 camera has a zoom lens.

The 1888 Kodak camera is kind of similar to the 1839 model, but it is almost twice as small, at only 16 cm in length. This model is made of metal, instead of wood, and it has four different control buttons on top of it. The 1925 Leica camera is also made of metal but looks more like a camera compared to the box-like older ones that were designed before. It also has a noticeable lens, and it is only 14 cms long, which is 2 cms shorter than the Kodak model.

Overall, the camera designs became smaller and more complex during the nineteenth and twentieth centuries.

Cell Phone Comparison Diagram Sample

The diagrams below show two stages in the development of the mobile phone.

Complete Report

The diagram shows how the design and functions of these two mobile phones have dramatically changed from the early models to the contemporary ones, over an unspecified period of time. It can clearly be seen that these two phone models have experienced several significant changes and developments.

To begin with, both the past and modern versions of these mobile phones have keypads to type information on, a screen to display this information, and the earphones to enable speaking and listening. They are both made of plastic, and their colour schemes are also much the same. The older model is longer and wider, and its overall weight is more, too. The new one is half the weight, 40mm shorter, and 10 mm less in width. This is where the similarities end.

There is a significant amount of difference between these two models. The early cellular phone had a black and white display screen, while the current one has a fully coloured one. The design of the new mobile phone has plenty of extra functions that have been added to the basic functions, like a more advanced selecting button compared to the earlier model. The newer phone has selections for email, internet, a music player, and game functions. The earlier model has none of these options.

Overall, the are many differences between the earlier and later models of these two cell phones that have been shown here.

Cement Production Comparison Diagram Sample

The diagrams below show the stages and equipment used in the cement-making process, and how cement is used to produce concrete for building purposes.

Complete Report

The two diagrams clearly illustrate the various steps and the tools that need to be used in the cement-making process. They also show how this is used to make concrete for building construction. The trend suggests that cement production is based on a dry process, while concrete production is used with water.

In the production of the cement diagram, there are about eight steps. The first part of the process is the mixing of limestone and clay in a crusher that produces a powder. The next step is the mixer followed by the rotating heater. At this step, heat is added to the mixture. After the heating process, the material goes into the grinder that produces dry cement. The final step is to put the cement into bags.

The second diagram shows the production of concrete. In step one 15% of cement and 10% of water is poured into a concrete mixer. 25% of this is also sand and 50% is gravel. All of these materials are mixed together in a clockwise rotating machine. This production process produces a wet mixture of concrete.

Overall, the two diagrams show the methods for dry cement production and wet concrete production.

Fire Plan Exit Comparison Diagram Sample

The diagram below shows the fire exit plan for the second floor of a student dorm building in a university.

Complete Report

The diagram shows the fire exit plan for the second floor of a university 7-bedroom dormitory. The trend suggests that there are two main exits from this floor leading to two stairwells, with one in the northeast corner of the building, labelled as “Meeting Point 2”, and the other in the southwest opposite corner of the building, labelled as “Meeting Point 1”. Bedrooms 1, 2 and 3 are closest to the southwest exit with bedroom 3 being exactly opposite to this fire escape. Bedrooms 1 and 2 are just around the corner from this exit. Room 1 just exits to the left of the door to access this exit, while room 2 exits to the right for immediate access. These three bedrooms should use “Meeting Point 1” Bedrooms 4, 5, 6 and 7 are nearest to the northeast fire exit. Bedroom 7 is right beside the exit, and room 5 is only a few steps from it. Both of these rooms access this exit to the right. Rooms 4 and 6 are across the hallway, with access coming again to the right of these rooms. These four bedrooms should use “Meeting Point 2.” Overall, two main fire exits are shown in this floor plan, with one at either end of the building.

Art Gallery Redevelopment Comparison Diagram Sample

The diagrams below are existing and proposed floor plans for the redevelopment of an art gallery.

Complete Report

The first picture shows the layout of an art gallery, and the second shows some proposed changes to the gallery space. It is clear that significant changes will be made in terms of the use of floor space in the gallery. There will be a completely new entrance and more space for exhibitions.

At present, visitors enter the gallery through doors, which lead to a lobby. However, the plan is to move the entrance to the Parkinson Court side of the building, and visitors will walk straight into the exhibition area. In place of the lobby and office areas, which are shown on the existing plan, the new gallery plan shows an education area and a small storage area.

The permanent exhibition space in the redeveloped gallery will be about twice as large as it is now because it will occupy the area that is now used for temporary exhibitions. There will also be a new room for special exhibitions. This room is shown in red on the existing plan and is not currently part of the gallery.

Overall, it is seen that a lot of changes might be made to the first-floor gallery.

Island Construction Comparison Diagram Map Sample

The two diagrams below show an island, before and after the construction of some tourist facilities.

Complete Report

The diagrams illustrate some changes to a small island, which has been developed for tourism. It is clear that the island has changed considerably with the introduction of tourism, and six new features can be seen in the second diagram. The main developments are that the island is accessible, and visitors have somewhere to stay.

Looking at the maps in more detail, it can see that small huts have been built to accommodate visitors to the island. The other physical structures that have been added are a reception building, in the middle of the island, and a restaurant to the north of the reception. Before these developments, the island was completely bare, or deserted, apart from a few trees.

As well as the buildings mentioned above, the new facilities on the island include a pier, where boats can dock. There is also a short road linking the pier with the reception and restaurant, and footpaths connect the huts. There is also a designated swimming area for tourists off a beach on the western tip of the island.

Overall, this map shows some changes to an island that experienced growth based on tourism.

University Sports Centre Comparison Diagram Sample

The plans below show the layout of a university's sports centre now, and how it will look after redevelopment.

Complete Report

The plans show how the current layout of the sports centre of a university changes to the new layout. The trend suggests a sizable redesign of the sports centre with the elimination of the outdoor courts and the addition of many different areas all around the complex.

Currently, in the middle of the sports centre, there is a 25-meter swimming pool. This pool remains in the future redesign and an additional larger leisure pool will be added. Around the swimming pool area are a gym, one changing area, some seating and a reception area. To the west side and east side of the sports centre are outdoor sports courts and access to the centre is made through the reception area.

After the redevelopment, the two outdoor courts in the current map will be replaced with a sports hall and a leisure pool and two more changing rooms will be added to the southwestern and south-eastern corners of the centre. In the future map, two new dance studios have been added both of which are next to the sporting hall on the eastern side of the hall. The gym area will also double in size and access to the different areas of the complete can be made throughout the centre.

Overall, the future plans for this sports centre involve a total redesign.

Stages in the Development of Cooking Equipment Comparison Diagram Sample

The diagrams below show the stages in the development of simple cooking equipment.

Complete Report

The diagrams show how modern cooking equipment evolved through three distinct stages. The trend suggests that each staging in the development of cooking was unique and as it developed cooking became more specialized and advanced.

Originally, as shown in diagram A, cooking used to be done with the help of a pot supported by some stones that were placed underneath the pot. The twigs and grass placed between the stones provided heat to the pot. In diagram B, a protective clay shield was used around the stones, which was used to protect the fire. A cooking pot could be easily placed on top of this clay shield for cooking purposes. Here some limited advances have been made.

The modern cooking device, as shown in diagram C, is totally different in look and function from the other two diagrams as it is much more advanced in design. The fire is completely enclosed in a metal covering and a door has been added for air supply and ash removal. The top consists of a grate on which charcoal can be placed. It is shielded by a clay-lining to prevent any heat loss. Besides a handle for easy transportation, this diagram also shows three metal supports at the top of the equipment to keep the pot in place.

Overall, the simple cooking device underwent drastic changes before becoming a modern cooking device.
