Learning Objective
I can explain how the greenhouse effect traps thermal energy converted from visible light.
- 1
Gases absorb specific colors of light because each atom and molecule has a set number of possible energy levels for its electrons.
- 2
The Earth emits infrared radiation because every object with a temperature above absolute zero will emit light, also known as thermal radiation.
- 3
Carbon dioxide molecules absorb infrared photons and then emit a photon back out in a random direction, some of which returns to Earth's surface, causing warming.
