SWYK LGC: Earth's Energy Budget

Front

What is Earth's energy budget?

Back

The energy coming in from the sun minus the energy being radiated out into space.

Front

What percentage of incoming solar radiation does not affect processes on Earth?

Back

29%.

Front

What is a greenhouse gas?

Back

A gas that traps heat in the atmosphere, contributing to the greenhouse effect. Example: carbon dioxide.

Front

Which surface is least likely to absorb solar energy and why?

Back

Snow, because it is white.

Front

What is the greenhouse effect?

Back

The process by which certain gases in Earth's atmosphere trap heat, keeping the planet warm.

Front

Name an example of a greenhouse gas.

Back

Carbon dioxide.

Front

What happens to solar energy that is not absorbed by the Earth?

Back

It is reflected back into space or absorbed by the atmosphere.

Front

How does the color of a surface affect its ability to absorb solar energy?

Back

Darker surfaces absorb more solar energy than lighter surfaces.

Front

What role do clouds play in Earth's energy budget?

Back

Clouds can reflect solar radiation back into space and also trap heat, affecting the energy balance.

Front

What is the main source of energy for Earth's climate system?

Back

The Sun.
