Deserts

Question 1

What is a characteristic feature of hot deserts?

Answer 1

They receive direct sunlight all the time.

This constant exposure to sunlight contributes to high temperatures during the day.

Question 2

Why is it much colder at the poles compared to deserts?

Answer 2

The sun’s energy has a longer distance to travel and a smaller area to penetrate at the poles.

This results in less intense heating compared to desert regions.

Answer 3

Heat escapes quickly.

This leads to significant drops in temperature, creating harsh conditions.

What is the second reason why deserts are dry?

Answer 5

Western edge of continents.

These areas often experience less rainfall due to geographical positioning.

Question 6

What is the third reason contributing to desert dryness?

Inland location.

Being far from oceans or large bodies of water reduces the availability of moisture.
