Question

Expansive soils expand and contract due to changes in water content. When the soil is wet, it swells and may exert pressure on any buildings or structures built on it. When the soil dries up, it contracts, causing the ground to sink or collapse. Temperature, mineral content, erosion rate, and building designs can also affect soil behavior, but they do not directly cause soil expansion and contraction.
