2.2 — rainfall and temperature patterns

Question 1

Explain

Where does high rainfall occur?

Answer 1

In low-latitude regions near the equator.

Question 2

Explain

Why does high rainfall occur where it does?

Answer 2

An increased amount of insolation leads to more evaporation of water, helping cloud coalescence.

Question 3

Explain

Where does moderate-high rainfall occur?

Answer 3

In mid-latitude regions.

(~23-55° latitudinally from the equator.)

Question 4

Explain

Why does moderate-high rainfall occur where it does?

Answer 4

It’s mostly created by the development of cold fronts within subpolar systems.

Question 5

Explain

Where does low rainfall occur?

Answer 5

In high-latitude regions, away from the equator.

Question 6

Explain

Why does low rainfall occur where it does?

Answer 6

lack of insolation promotes less evaporation
less evaporation means no cloud coalescence and rainfall.

(this is the reason why oceans don’t get much rainfall)

Question 7

Explain

Why coastal areas experience more rainfall than inland areas?

Answer 7

• Humidity causing evaporation
• Winds aiding evaporation
