Wave energy does the work of erosion at the shore Waves approach the shore at some angle so the inshore part of the wave reaches shallow water sooner than the part that is further out The shallow part of the wave ‘feels’ the bottom first This slows down the inshore part of the wave and makes the wave “bend” This bending is called Erosion is a mechanical process, usually driven by water, wind, gravity, or ice, which transports sediment and soil from the place of weathering Liquid water is the main agent of erosion Gravity and mass wasting processes (see Chapter 10, Mass Wasting) move rocks and sediment to new locations Gravity and ice, in the form of glaciers (see 52: Weathering and Erosion Geosciences LibreTextsThis chapter focuses on changing surface of the earth and the sedimentary rock The face of the earth is being changed by erosion and deposition Agents of erosion include wind, moving water, and ice When rocks are exposed to the atmosphere, they undergo chemical weathering This changes feldspars in igneous rocks to clay, and minerals CHANGING SURFACE OF THE EARTH AND SEDIMENTARY ROCKS
