Question

Low atmospheric pressrue exists on the earth in which of the following latitudes?

(a) at the equator only
(b) at 30° N and S
(c) at the Poles
(d) at the equator and at 60° N and S

Answer 1

(d) at the equator and at 60^o N and S
At equator, earth gets maximum heat from the sun. Thus, air gets warm and rises up creating a low pressure area. At 60^o N and S, air is again warmer than the air at poles; therefore, it rises up and creates a low pressure area.
