The major agent responsible for erosion on the Earth's surface is water. Flowing water as a result of rain, melting glaciers, moving streams and rivers erodes surfaces by displacing bits of soil and rocks, which is then moved from its original location to another. Erosion from water can result in valleys and rivers being widened and can even create new canyons over time.
Water from the ocean in the form of waves constantly smashing against seaside cliffs and beaches can cause significant erosion. Erosion from seawater can cause caves to form and can cause rock columns called sea stacks to form, which can be dangerous. Erosion is a process in which ice, water and wind or a combination of all of the agents combined wear away at the Earth over time, eventually resulting in the creation of new land forms and property destruction.
