Front

Why is air warmer and less dense at the equator?

Back

Because the equator receives more solar radiation.

Front

In which direction do prevailing westerlies flow?

Back

From west to east.

Front

What is the low pressure zone that separates the Westerlies and Easterlies called?

Back

Polar Front.

Front

What causes differences in air pressure?

Back

Uneven heating of the earth.

Front

What is the definition of solar radiation?

Back

Solar radiation is the energy emitted from the sun in the form of light and heat.

Front

What are the two main types of global winds?
