Assertion (A): The great deserts of the world lie near twenty to thirty degrees latitude.
Reason (R): Air descends in the subtropical high pressure belt, warming and drying as it sinks.

  • A.Both A and R are true, but R is not the correct explanation of A
  • B.A is true but R is false
  • C.A is false but R is true
  • D.Both A and R are true, and R is the correct explanation of A

Answer: D

Both are true and the reason gives the mechanism: subsiding air cannot produce precipitation, and the Sahara, Arabian and Australian deserts all lie in that belt. Descent suppresses rain entirely. The belt shifts with the seasons.
