Wind

Question 1

How are winds formed?

Answer 1

The unequal heating of the atmosphere and the Earth’s rotation leads to movements of air over the Earth’s surface (wind).

Question 2

Where do winds blow from?

Answer 2

Areas of high pressure to areas of low pressure.

Question 3

What creates low pressure at the equator?

Answer 3

When air is heated, it expands. This makes it lighter and so it rises.

Question 4

Where does the air begin to cool?

Answer 4

At about 30° north and south of the equator.

Question 5

What creates high pressure?

Answer 5

When air is cooled it becomes heavy and sinks towards the Earth’s surface.

Question 6

Where does most of the sinking air move back to in the equator?

Answer 6

Between 30° latitude and the equator.

Question 7

Where does the rest of the air flow go?

Answer 7

Towards the poles.
