SpletShrink-swell of clay soil occurs because of moisture content. A rainy season can cause the clay soil to retain moisture and cause it to swell. A dry season or drought can cause the soil to shrink, or decrease in volume. Why is this important to you? Soils that shrink and swell can cause property and infrastructure damage.

In an isotonic environment, there is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell. Image credit: Mariana Ruiz Villareal dr nekoba huntsman
