Question

Give a geographical reason to explain the following:

In arid regions, trees are planted in rows perpendicular to wind direction.

Answer 1

In arid regions, strong dry winds blow across exposed land and remove the fertile topsoil; planting trees in several rows as shelter belts perpendicular to the wind acts as a windbreak that reduces wind speed, traps drifting sand and dust, and thereby prevents wind erosion, conserves soil moisture and protects crops and cultivated land.
