Question

Quizplus · Accepted Answer

Earth's coastlines are relatively young in geologic time, and are constantly being reshaped by a variety of processes including erosion, sedimentation, and tectonic activity. This means they are undergoing continuous change, as opposed to having the oldest landforms on the planet or showing a remarkable degree of similarity across the globe. There are also many inputs that affect coastlines beyond tidal action, such as storms, sea level changes, and human activities.
