Question

Quizplus · Accepted Answer

Expansive soils are a problem only in areas with pronounced wet and dry seasons. These soils are characterized by a high content of clay minerals, which can swell when they absorb water and shrink when they lose water. This cycle of swelling and shrinking can cause significant damage to structures built on or in these soils, particularly in areas with pronounced wet and dry seasons.

Therefore, option B is the correct answer.
