My imaginary planet

The name of my imaginary planet is Greasy, because the food they eat is greasy. In the Solar System is the third planet but not everybody can see it only good and with imagination people can do it. The orbit is unusual because is without shape. Its size is small. The diameter of the planet is 3 thousand kilometers with a mass of 100 tones. Gravity is half than on the Earth. The atmosphere is made of oxygen. It has 19 moons, and doesn´t have Rings. Greasy is two light years from the Earth. When you see it from the Earth is purple. The year is 487 days long. One day lasts 36 hours. The temperature during the winter is 18ºC and during the summer 39ºC. The habitants are called Greasys and they are tall and strong: they have two hands with 3 fingers, two feet, with five toes, black eyes and hair of different colours. They are polite and doesn´t have sex. The place where they live is amazing. They have chocolate rivers and seas, the mountains are made of pasta and the houses of fruit and meat. I´d like to live there because it´s no crime and is not pollution because there aren´t any cars. I´d recommend for good person because you can see this planet and other people are going to thanks you.

Describe a Planet: Saturn

Saturn is the sixth planet from the Sun and the second largest planet in the Solar System, after Jupiter. Saturn is a gas giant. Saturn's interior is probably composed of a core of iron, nickel, rock silicon and oxygen compounds. Saturn has a ring system that consists of nine continuous main rings and three discontinuous arcs, composed mostly of ice particles, rocky and dust. Sixty-two known moons orbit the planet; fifty-three are officially named. This does not include the hundreds of "moonlets" within the rings. The average distance between Saturn and the Sun is over 1.4 billion km. There have been three main phases in the observation and exploration of Saturn. The first era was ancient observations (such as with the naked eye), before the invention of the modern telescopes. Starting in the 17th century progressively more advanced telescopic observations from earth have been made. The other type is visitation by spacecraft, either by orbiting or flyby. In the 21st century observations continue from the earth (or earth-orbiting observatories) and from the Cassini orbiter at Saturn.

Conditions for live WATER: Liquid water is the first condition of live. The temperature must be warm to keep water liquid.

METEOROLOGICAL FEATURES: The atmosphere and the ozone lawyer contribute to soften the temperatures. Life would not be possible under very extreme meteorological conditions such us strong winds, violent storms or very severe volcano eruptions.

ATMOSPHERE: The atmosphere and the ozone layer protects us from solar harmful rays. It works like a greenhouse, water

GRAVITY: Earth´s suitable gravity contributes to keep the atmosphere and the liquid water in the oceans.

CHERMICAL COMPOUNDS: Oxygen, hydrogen, carbon and nitrogen are essential to enable life on a planet.

FIRST LIVING CELLS: The first living cells in developed in water, similar to algae. Bacteria were one of the first forms of life on Earth. Plants and animals got adapted to the life because the ozone layer was already formed and protected. If you look at any animal, you will realise that its body is adapted to the place it lives and the foot it eats.

THE KYOTO PROTOCOL In 1997, governments met in the Japanese city of Kyoto where they agreed on cutting emissions of greenhouse gases. They wrote a document, the Kyoto protocol. This protocol affects those developed industrial countries responsible for creating most of emissions. The developed countries commit themselves to reduce their collective emissions of six key greenhouse gases by at least 5%. Each country's emissions target must be achieved by the period 2008-2012.

GLOBAL REPONSIBILITY Reducing the emission of greenhouse gases is every country´s and every persons person´s responsibility. However some countries emit more gases than others.

THE GREEN HOUSE EFFECT The greenhouse effect is a natural process that keeps the Earth at a temperature that is suitable for life. It´s created by gases in the atmosphere that absorb heat. The problem is that the greenhouse effect is getting stronger. Several factors intervene in the greenhouse effect, some natural and some created or at least augment ed by human activity.

Conclusions # I think that in the past it was less pollution than now, because there weren´t factories, spray cans, cars… # Nowadays if we don´t take care we can kill the planet and no more people will live in this planet #We have to be more responsible with the use of the electricity and other sources of energy. #We have to be careful with the waste production. #We have to improve new technologies to better use our natural resources. #I think that in the future we are going to die because the pollution is going to be more and we won´t emigrate to another planet.
