Question
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
Venus has a surface of high mountains which absorb heat.
Mars has a thin atmosphere that cannot hold much heat.
Venus has a thick atmosphere which blocks heat from the surface.
Mars has a surface of red rocks and sand which reflect heat.
Venus has a thick atmosphere which blocks heat from the surface.
Why is venus the hottest solar system planet
1. it has a core, mantle and a crust
2. its atmosphere is rich in carbon dioxide gas
3. it has abudance of nitrogen and oxygen gasses
4. its closest to the sun
The correct answer is: Venus has a thick atmosphere which blocks heat from the surface.
To determine the correct answer, we need to analyze the properties of the two planets, Mars and Venus. Both planets have atmospheres that contain mostly carbon dioxide. The key here is to identify which property of each planet is responsible for the difference in surface temperatures.
Let's go through each option:
1. Venus has a surface of high mountains which absorb heat.
This statement does not explain the temperature variation, as the presence of high mountains on Venus does not directly affect the temperature differences between Mars and Venus.
2. Mars has a thin atmosphere that cannot hold much heat.
This statement does not explain the temperature variation either. While it is true that Mars has a thinner atmosphere compared to Venus, it does not necessarily mean that Mars cannot hold heat.
3. Venus has a thick atmosphere which blocks heat from the surface.
This is a plausible explanation. Venus indeed has a much thicker atmosphere than Mars, and the dense atmosphere traps heat from the Sun, causing a greenhouse effect and resulting in high surface temperatures.
4. Mars has a surface of red rocks and sand which reflect heat.
This statement does not adequately explain the temperature variation, as the color of the rocks and sand on Mars does not significantly contribute to the temperature difference between the two planets.
Considering these options, the best explanation for the temperature variation between Mars and Venus is that Venus has a thick atmosphere which blocks heat from the surface. Therefore, the correct answer is option 3: Venus has a thick atmosphere which blocks heat from the surface.
