Which of the following lists two reasons why it is so cold on mars?

a. none of the above.

b. far from the sun (so less warmth from the sun) and no volcanoes to warm the surface

c. no volcanoes to warm the surface and a thick atmosphere, which prevents sunlight from penetrating to the surface.

d. mars is far from the sun (less warmth from the sun) and very little greenhouse warming due to its very thin atmosphere.

Option D.

Explanation:

Mars is far from the Sun (less warmth from the Sun) and very little greenhouse warming due to its very thin atmosphere, is the right answer.

As the earth is distant from the sun so as the heat of the sun does not reach to mars. Another important reason why the climate on Mars is cold is that barren planet also has a shallow atmosphere that is 95% carbon dioxide. The distribution of Mars’ climate is remarkably comparable to Venus’, one of the least congenial atmospheres in all of the Solar System.
