Question

question 43 1 pts not all gases are greenhouse gases. which of the following would be a greenhouse gas? a gas that does not absorb heat that radiates away from the earths surface a gas that absorbs heat that radiates away from the earths surface a gas that participates in biogeochemical cycling in the biosphere a gas that does not participate in biogeochemical cycling in the biosphere

Explanation:

Greenhouse gases, such as carbon dioxide and methane, absorb infrared radiation (heat) that radiates from the Earth's surface. This absorption is a key part of the greenhouse effect. Biogeochemical cycling (like the carbon cycle) is not the defining characteristic of a greenhouse gas. A gas that doesn't absorb heat would not be a greenhouse gas.

Answer:

a gas that absorbs heat that radiates away from the Earth's surface
