Question

Give a geographical reason for the following:

Equatorial regions have low atmospheric pressure throughout the year.

Answer 1

Equatorial regions have low atmospheric pressure throughout the year because they receive direct vertical sunlight throughout the year.

This intense solar heating causes:

• Air to warm up and rise rapidly (convection),

• Creating a zone of low pressure near the surface.

Since this heating is constant year-round, the low pressure remains stable, making the Equatorial region a permanent low-pressure belt.
