The correct response is: It has a thick atmosphere that traps heat.
To answer why Venus is the hottest planet in the solar system, we need to analyze the responses provided:
1. It has an abundance of nitrogen and oxygen gases.
This response is incorrect because Venus' atmosphere is primarily composed of carbon dioxide, not nitrogen and oxygen gases.
2. It is closest to the sun.
This response is incorrect because although Venus is closer to the sun than Earth, its proximity to the sun alone does not make it the hottest planet.
3. Its atmosphere is rich in carbon dioxide gas.
This response is correct. Venus has a thick atmosphere consisting mainly of carbon dioxide, which creates a strong greenhouse effect. This effect traps heat from the sun and contributes to Venus being the hottest planet in the solar system.
4. It has a core, a mantle, and a crust.
This response is unrelated to the question. The presence of a core, mantle, and crust is not the reason why Venus is the hottest planet.
Therefore, the correct response is that Venus is the hottest planet due to its atmosphere being rich in carbon dioxide gas.
