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)

Question

6 O
Item 1
CO G Go Go
• Venus has a thick atmosphere which blocks heat from the surface.
O Venus has a surface of high mountains which absorb heat
• Mars has a thin atmosphere that cannot hold much heat.
O Mars has a surface of red rocks and sand which reflect heat.

Answer 1

The correct answer is: Venus has a thick atmosphere which blocks heat from the surface. This is because Venus' atmosphere is composed of dense clouds of carbon dioxide, which create a greenhouse effect that traps heat and raises the planet's surface temperature to extreme levels. Mars, on the other hand, has a thin atmosphere that cannot hold much heat, resulting in significantly lower surface temperatures.
