Guided Notes
Key concepts students will learn:
- •
Gases absorb specific colors of light because each atom and molecule has a set number of possible energy levels for its electrons.
- •
The Earth emits infrared radiation because every object with a temperature above absolute zero will emit light, also known as thermal radiation.
- •
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.
