What proccess is responsible for constantly wearing away the earths surface?

Erosion

Explanation:

     Erosion is the process of wear, transport and sedimentation of soil, subsoils and rocks as an effect of the action of erosive agents, such as water, winds and living beings. The process of disaggregation of rock particles (called sediments) is caused by the action of weathering (a set of chemical, physical and biological processes that cause soil and rock wear). These sediments are transported by gravity and surface elements.
