Unit 4: Earth's Energy Budget Test Review

Front

Why is the sun important in the formation of most energy sources on Earth?

Back

The sun's radiation drives photosynthesis, creating chemical energy in plants

Front

How much of the incoming solar energy can affect processes on Earth?

Back

71%

Front

What is Earth's energy budget?

Back

The sum of Earth's incoming solar energy minus Earth's outgoing energy.

Front

A student drops a solid piece of foam in boiling water. The piece of foam rises to the top of the container, gets pushed to the side, sinks to the bottom, and then rises again repeatedly. What causes the foam to move in a circular motion?

Back

Convection

Front

What kind of change occurs in the wood when it burns and releases heat?

Back

chemical

Front

What are secondary sources of energy used for?

Back

Storing and delivering energy easily in usable form

Front

WHAT IS THE MAIN COMPONENT OF SOLAR RADIATION?
Options: Infrared, Ultraviolet, Visible light, Gamma rays

Back

Visible light

Front

How does ultraviolet radiation from the sun harm our skin?

Back

It causes sunburns and skin damage.

Front

How could variations in Earth's energy budget impact climate patterns?

Back

Changes in the energy budget can lead to shifts in climate systems

Front

Which is an example of how potential energy is naturally stored in our environment?

Back

Chemical energy from the sun is transformed into stored potential energy in fossil fuels.
