On Earth, the atmosphere helps make life possible. The gas in outer planets is mostly hydrogen and Venus and Mars have mostly carbon dioxide in their atmospheres. The lack of a magnetic field on Mars caused a near-total loss of its atmosphere. The still-moving atmosphere would scour landscapes. Earth is at an adequate distance from the sun which gives us heat that is neither too hot nor too cold. The fossil record informs us that existence on the planet has lasted a minimum of 3. Many scientists believe that there probably is other life in the universeand NASA has even created an entire mission dedicated to searching for life called the Kepler Mission. Moreover, students of all ages, including college students and adults, have difficulty understanding what causes the seasons. Earth's amazing gaseous atmosphere is responsible for making life possible on this, the third planet from the Sun. Smithsonian National Air and Space Museum. An astronaut on Mars would not be able to breathe the Martian air and would need a spacesuit with oxygen to work outdoors. The planets nearest to the star tend to be rockier because the stars wind blows away their gases and because they are made of heavier materials attracted by the stars gravity. @media(min-width:0px){#div-gpt-ad-ourplnt_com-narrow-sky-2-0-asloaded{max-width:300px!important;max-height:250px!important}}if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[300,250],'ourplnt_com-narrow-sky-2','ezslot_18',602,'0','0'])};__ez_fad_position('div-gpt-ad-ourplnt_com-narrow-sky-2-0'); According to simulations, without the two biggest gas giants in the Solar System, Jupiter, and Saturn, life may not have been able to gain a foothold on Earth.

Why is life possible only on the planet Earth? All of these are the various factors which make existence on the planet possible. We know that life requires sun, moderate temperatures, water, and certain chemical elements like carbon, oxygen, and nitrogen. Because of Mars very low atmospheric pressure any water that tried to exist on the surface would quickly boil away. It is not too hot, like Venus, and not too cold, like Neptune. Earth has a protective ozone layer which protect us from the harmful rays.
