THE UNIVERSE

BY: IKER


MARS Mars is the fourth planet from the Sun in the Solar System. Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the volcanoes, valleys, deserts, and polar ice caps of Earth. The rotational period and seasonal cycles of Mars are likewise similar to those of Earth, as is the tilt that produces the seasons. Mars is the site of Olympus Mons, the highest known mountain within the Solar System, and of Valles Marineris, the largest canyon. Liquid water cannot exist on the surface of Mars due to low atmospheric pressure, except at the lowest elevations for short periods.The two polar ice caps appear to be made largely of water Mars lost its magnetosphere 4 billion years ago,so the solar wind interacts directly with the Martian ionosphere, lowering the atmospheric density by stripping away atoms from the outer layer. Mars has two relatively small natural moons, Phobos and Deimos, which orbit close to the planet. Mars’ average distance from the Sun is roughly 230 million km (1.5 AU) and its orbital period is 687 (Earth) days. The solar day (or sol) on Mars is only slightly longer than an Earth day: 24 hours, 39 minutes, and 35.244 seconds


MYIMAGINARY PLANET:

The Biscuit planet is the forth planet from the sun.It is a very small planet you can't see.It is composed of small pieces of chocolate.It needs 456 days to orbiting the sun.It has ten moons.It has got four rings.This planeet hasn't got gravity and inhabitauts they can fly. The atmosphere is composed by oxygen and hydrogen.The temperature is colder than on the Earth.This planet is light brown.In this planet live very strange people,there are shorts and then face is round.They don't breath oxygen,they breath hydrogen!They drink milk because there isn't any animals,no dogs,no cats,no fishes...but there are plants can speak and fly because of gravity.They speak a very strange language.This planet was discovered in 2004 by an astronaut named Peter Biscuit in his filight to Mercury,he was surprised,there was a planet made of mass and chocolate. The scientifics say that there are going to investigate on this planet and there are going to send an artificial satellite soon .We are waiting results.


CONDITIONE FOR LIFE WATER: water is the first condition for life . The temperature must be warm. METEOROLGICAL FEATURES: the atmosphere and the ozone layer contribute to soften the temperatures. Life would not be possible under very extreme meteorolgical conditions. ATMOPHERE: the atmophere and the ozone layer protects us from solar harmful rays. GRAVITY: gravity contributes to keep the atmophere and the liquid wateer in the oceans. CHEMICAL COMPOUNDS: oxygen,hydrogen,carbon and nitrogen are ess


1. I think that the Universe is very interesting because we

don’t know everything of it. 2. I think that the Universe is very big. 3. I think that in the Universe are a lot of interesting things

for example: stars, comets… 4. We life on the Earth because is the only planet with water,

oxygen and things we need to live. We can´t pollute the Earth because if we pollute the Earth in the future we can´t live in it. 5. I think that in the future there could be an explosion and

that another planet will be formed but we won´t live on it because it won´t have water, oxygen and other things we need to live. 6. I think that in the future the Earth will be polluted


THE KYOTO PROTOCOL


In 1997, governments met in the Japanese city of jyoto where they agreed on cutting emissions of greenhouse dases. They wrote a document, the kyoto Protocol.This protocol affects those developed industrial countries responsible for creating most of the emissions. The developed countries commit theselves to reduce their collective emissions of six key greenhouse gases by at least . Each country´s emissions target must be achieved by the period 2008-2012. º
