The sun produces waves called radiation.

-Heat is absorbed by the surface and reflected by particles in the atmosphere.

Solar Radiation

Types of Solar Radiation

Visible Light- What we see

Ultraviolet- Waves are closer together than visible light, can damage skin and cause cancer.

Infrared- Waves are further apart than visible light, can be used for remote controls, heat sensors and night vision.

Earth's Energy Budget

Energy Moves

Earth’s energy budget refers to the tracking of how much energy is flowing into and out of the Earth’s climate, where the energy is going, and if the energy coming in balances with the energy going out

The Earth’s energy budget includes the solar energy entering and exiting Earth’s atmosphere. Excess carbon dioxide and other gases affect the energy budget, creating a greenhouse effect

​

Greenhouse Gas

Multiple Choice

If we took out most of the water, carbon dioxide and methane gas from the atmosphere, the greenhouse effect would be weaker and the temperature would

• Increase

• decrease

Multiple Choice

What surface is least likely to absorb solar energy?

• rock

• snow

• water

• streets

Heat Transfer

Conduction- heat transfer by touching

Convection- heat transfer by moving air or water

Radiation- heat transfer through waves

Energy moves

Thermal and radiant energy can be converted into mechanical energy, chemical energy, and electrical energy and back again

Thermal- heat

Radiant- Electromagnetic waves (light, microwaves, UV, etc.)

Mechanical- potential and kinetic

Chemical- energy stored in chemical bonds (food, bateries, etc.)

Multiple Choice

• Wind

• Coal

• Hydroelectric

Multiple Choice

Energy Transfer when coal is burned

• mechanical to thermal

• chemical to radiant

• chemical to thermal

• solar to electrical
