Answer : Earth is the only planet that has life. Life on earth depends on many factors like temperature, humidity, availability of water, food, and shelter etc. the resources available on earth and the energy from the sun are necessary for life on earth.

Venus is the second planet from the sun. It is the second natural object in the sky which appears bright after the moon.

Mars is the fourth planet from the sun and second smallest in the solar system. It is also called the red planet.

The layer of gasses that cover the planet like a blanket is called the atmosphere. The earth atmosphere is differ from venus and mars as follows:

The earth’s atmosphere consists of a number of gasses, it is a mixture of nitrogen, oxygen, carbon dioxide, water vapor and other gasses, mostly of nitrogen(N), and oxygen(O2). This atmosphere keeps the temperature of the earth and supports life on earth.

Venus has a thick toxic atmosphere which is fully filled with carbon dioxide, it has a thick yellowish sheet of sulfuric acid (H2SO4) that traps heat which causes the Greenhouse effect.

The atmosphere of Mars is thinner than that of the earth’s atmosphere. Mars’ planet atmosphere contains more than 95% of carbon dioxide and oxygen contains less than 1%.

The atmosphere of mars and venus differs with earth by containing carbon dioxide with 95-97%. This may be the reason for no life on mars and venus
