Energy and Earth's Structure

Front

Main source of energy on Earth's surface

Back

The Sun

Front

Reason for different energy amounts at locations

Back

The sun shines less directly on the poles, and more directly at the equator.

Time of day with least solar energy

Back

Night

Front

Effect of no Earth tilt on seasons

Back

We would not experience seasons.

Front

Energy distribution across Earth's surface

Back

Energy transfers through currents in water and air, from high energy at the equator to low energy at the poles.

Convection cells in the atmosphere

Back

There are about three convection cells between the equator and the poles.
