Global warming 1.- This article is about the change in climate that Earth is currently experiencing. For general discussion of how Earth's climate can change 2.- Global warming is the rising average temperature of Earth's atmosphere and oceans since the late 19th century 3.- the early 20th century, Earth's average surface temperature has increased by about 0.8 째C (1.4 째F), with about two thirds of the increase occurring since 1980 4,- most of it is caused by increasing concentrations of greenhouse gases produced by human activities such as deforestation and the burning of fossil fuels. 5.- increase in global temperature will cause sea levels to rise and will change the amount and pattern 6.- Warming is expected to be strongest in the Arctic and would be associated with continuing retreat of glaciers, permafrost and sea ice 7.- If global mean temperature increases to 4 째C (7.2 째F) above preindustrial levels, the limits for human adaptation are likely to be exceeded in many parts of the world, while the limits for adaptation for natural systems would largely be exceeded throughout the world.

Mar s 1-.Mars is the fourth planet from the Sun in the Solar System 2.-it is often described as the "Red Planet" as the iron oxide prevalent on its surface gives it a reddish appearance 3.-The rotational period and seasonal cycles of Mars are likewise similar to those of Earth, as is the tilt that produces the seasons 4.-Mars is the site of Olympus Mons 5.-He has the highest known mountain within the Solar System, 6.-There aremany speculated about the presence of liquid water on the planet's surface


People sees dad in Mars there are water, but no body see them.


The atmosphere of Mars is very flimsy. The atmospheric presion change when the altitude change.


The medium temperature in Mars there is of 200ºC.


In Mars, there are more gravity than in the moon but the gravity are less than in the Earth.


In Mars there are chemical compounds such as metano, “monósido de carbono” and “el vapor de agua”.


1.- We weel side the planet because when we weel not side the planet the planet can esting, or contaminated. 2.- I thik that in the future the universe will satart a gain. 3.-I think that in the future the universe exploded a result of a process the Sun and the Earth will start a gain. 4.-I think that in the future will invent one mass to go the space. 5.- I think that in the future i can go to the moon. 6.-I think that in the future the one person could invent one cloth i can go to the sapace

MY IMAGINARY PLANET Planet name: Narning. My planet is the fourth planet from th Sun, near the Earth. This planet was named after my tho logical gods. My planet is bigger than the others. The orbit from: the Sun is 3000 kilometers. The diameter of the planet is 800 kilometers. The planet´s mass is 600 kilograms. It has only one moon. A year on my planet is 400 days. A year o my planet is 30 hours. Wee can see it with a telescope. It´s a rocky planet. It has rocks. It´s a thick atmosphere. The range of temperature is from 1ºC to 30ºC the season are the same than in the Earth. There is one ring orbiting my planet. This ring is thin. In my planet humans can live. %50 of my planet is water. The moon was discovered in 1969. In my planet monsters live.

Black hole 1.-A black hole is a region of spacetime where gravity prevents anything, including light, from escaping. 2.-The theory of general relativity predicts that a sufficiently compact mass will deform spacetime to form a black hole. 3.-It is called "black" because it absorbs all the light that hits the horizon. 4.-Quantum mechanics predicts that black holes emit radiation like a black body with a finite temperature. 5.-This temperature is inversely proportional to the mass of the black hole. 6.-By absorbing other stars and merging with other black holes.
