MCQ
Nights in deserts are much cooler because:
  • A
    Humidity becomes high
  • Sand cools down faster
  • C
    Wind blows vigorously
  • D
    It rains at night

Answer

Correct option: B.
Sand cools down faster
Nights are cooler in the deserts than in the plains because Sand radiates heat more quickly than the earth. Because deserts have such little water vapor in the air, it makes it harder to trap heat or cold in a desert.
