Question

Greenhouse gases include carbon dioxide and methane. How do greenhouse gases act to increase air temperatures near Earth's surface?

A. They transmit visible light that enters the atmosphere.
B. They trap heat that is radiated from the surface.
C. They reflect heat that enters the atmosphere.
D. They emit heat when they undergo chemical reactions.

Answer 1

B, They trap heat that is radiated from the surface.

Step-by-step explanation:

Greenhouse gases are more complex than other gas molecules in the atmosphere, with a structure that can absorb heat. They radiate the heat back to the Earth's surface, to another greenhouse gas molecule, or out to space. There are several different types of greenhouse gases.
