Question

question 25 of 30
which of the following clean the earths atmosphere?
a. rain forests
b. oceans
c. deserts
d. mountains

Explanation:

Rain forests play a crucial role in cleaning the Earth's atmosphere. Through photosynthesis, they absorb carbon dioxide ($CO_2$) and release oxygen ($O_2$), helping to regulate the composition of the atmosphere. Oceans also contribute to the carbon cycle but their primary role is not as direct in "cleaning" the atmosphere in the same sense as rain forests. Deserts have very little vegetation and thus minimal impact on atmospheric cleaning through photosynthesis. Mountains mainly affect weather patterns and do not have a significant direct role in cleaning the atmosphere.

Answer:

A. Rain forests
