Solar Energy Travel
What are the 3 ways solar energy travels to earth?
infrared, visible light, ultraviolet
What is Earth's energy budget?
how Earth's energy is distributed
What is heat?
energy transferred between objects that are different temps
What is conduction?
transfer of heat through touch
A car moving is an example of what type of energy?
mechanical energy
What type of solar energy has the longest wavelength?
infrared
Why is Earth's energy budget important?
it determines Earth's climate
radiation, conduction, convection
What is an example of conduction?
touching a hot stove, heating a pan on a burner, etc
Food is an example of what type of energy?
chemical
What type of solar energy has the shortest wavelength?
UV
What percentage of Earth's energy comes from the sun?
100%
What is an example of radiation?
sitting in the sun, by a fire, etc
What is convection?
transfer of heat by the movement of a liquid or gas
the sun or a power plant.
What is infrared?
invisible and felt as heat
What is the greenhouse effect?
Gases in the atmosphere trap heat and helps earth maintain its temperature
What is radiation?
The heat you feel from the sun. Heat you feel without touching an object.
What is an example of convection?
heat rising upstairs or a convection oven
A lamp can be an example of what 3 types of energy?
electrical, radiant, thermal, or mechanical
What does ultraviolet radiation cause?
skin cancer, eye damage, and sunburn
What happens to the sun's energy when it radiates to earth?
some is reflected and some is absorbed
Why is heat transfer important?
It affects temp, winds, and precipitation.
Energy cannot be created or destroyed
What is an energy transformation?
a transfer of one form of energy to another
