Question

Carbon dioxide is called greenhouse gas because it is:

• A. Transparent to both sunlight and heat
• B. Used in the greenhouse to increase plant growth
• C. Transparent to heat but traps sunlight
• D. Transparent to sunlight but traps heat

Answer 1

The correct option is D

Transparent to sunlight but traps heat

Materials like air, water, and clear glass are called transparent. When light encounters transparent materials, almost all of it passes directly through them.
A greenhouse gas is a gas in an atmosphere that absorbs and emits radiant energy within the thermal infrared range. This process is the fundamental cause of the greenhouse effect. Carbon dioxide and chlorofluorocarbons are examples of greenhouse gases.
