What is one of the most common causes of foundation settlement?
Foundation Settlement is due primarily to the expanding soil cycle (shrinkage and expansion) directly dependent on water content. This constant movement weakens and softens soils and can also create pockets/voids beneath your home's foundation, which your home will sink/settle into following the laws of gravity.

Why does soil shrink?
Soils that have a lot of clay content in them can also generally have a tendency to shrink when it comes to the loss of moisture. As soils with high clay contents begin to dry out, they can contract or shrink. This is going to result in the general and gradual decrease of the soil’s volume. As a result, settlement damage is often going to be observed when it comes to structures that are supported on soil that has become dried out. Drying out of the foundation soil can often be caused by conditions that are extensively drought-like as well as other causes. For example, maturing vegetation and trees can cause a drying out of the foundational soil. Another cause for drying of the foundation soil is a leaking of an HVAC or heating, ventilation and air conditioning system in the subfloor.
