The student should recognize that regressions imply a period of falling sea level in which the
ocean recedes from the continent. By contrast, a transgression implies a period of rising sea
level in which oceans cover more of the continental masses. These changes can be caused by
climatic or tectonic factors. A good example is the lowering of sea level that accompanies an ice
age when more water is contained as ice in glaciers lowering sea level
