Which of the following best explains why Mars' and Venus' surface temperatures vary, despite both planets having atmospheres that contain mostly carbon dioxide?(1 point)
Responses
Mars has a surface of red rocks and sand which reflect heat.
Mars has a surface of red rocks and sand which reflect heat.
Mars has a thin atmosphere that cannot hold much heat.
Mars has a thin atmosphere that cannot hold much heat.
Venus has a thick atmosphere which blocks heat from the surface.
Venus has a thick atmosphere which blocks heat from the surface.

Venus has a surface of high mountains which absorb heat.
The best explanation for why Mars' and Venus' surface temperatures vary, despite both planets having atmospheres that contain mostly carbon dioxide, is:
Mars has a thin atmosphere that cannot hold much heat.
While Venus has a thick atmosphere that effectively traps heat (creating a greenhouse effect), Mars' thin atmosphere allows heat to escape easily.

It has a core, a mantle, and a crust.
Its atmosphere is rich in carbon dioxide gas.
The correct response is:
Its atmosphere is rich in carbon dioxide gas.
Venus is the hottest planet in the solar system primarily due to its thick atmosphere, which is composed mostly of carbon dioxide, leading to a strong greenhouse effect that traps heat.
