Energy in Earth's Atmosphere

1. The warming of Earth's surface due to the trapping of heat by certain gases in the atmosphere.
3. A colorless, odorless gas produced by burning carbon. A major greenhouse gas.
5. The process by which heat is directly transmitted through a substance when there is a difference in temperature.
7. Gases in Earth's atmosphere that trap heat and contribute to the greenhouse effect.
9. To bounce back light or heat without absorbing it, like what clouds do to sunlight.
10. The energy that comes from heat; this energy moves between objects of different temperatures.
13. The layer of gases surrounding Earth, protecting us and providing the air we breathe.
15. Energy sources that cannot be replenished within a human lifespan, like coal, oil, and natural gas.

2. Energy that is emitted in the form of rays, waves, or particles.
4. The transfer of heat by the movement of a fluid (like air or water) from one place to another.
6. To take in or soak up energy, like what Earth’s surface does to sunlight.
8. The balance between the energy Earth receives from the sun and the energy it emits back into space.
11. A potent greenhouse gas with a global warming potential many times that of carbon dioxide, emitted by natural processes and human activities.
12. Sources of energy that can be replenished naturally, like wind, solar, and hydro power.
14. The ability to do work or cause change, found in many forms like light, heat, and electricity.
