Deserts Flashcards
What is a characteristic feature of hot deserts?
They receive direct sunlight all the time.
This constant exposure to sunlight contributes to high temperatures during the day.
Why is it much colder at the poles compared to deserts?
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.
What happens to heat in deserts at night?
Heat escapes quickly.
This leads to significant drops in temperature, creating harsh conditions.
Name one reason why all deserts are dry.
Hadley cell.
This atmospheric circulation pattern creates arid conditions in desert regions.
What is the second reason why deserts are dry?
Western edge of continents.
These areas often experience less rainfall due to geographical positioning.
What is the third reason contributing to desert dryness?
Rain shadow.
This occurs when mountains block moisture-laden winds, leading to dry conditions on the leeward side.
What is the fourth reason for desert dryness?
Inland location.
Being far from oceans or large bodies of water reduces the availability of moisture.
Fill in the blank: Changes in temperature can be very ______ for a human.
harsh.
Extreme temperature fluctuations can pose health risks.
