Answer:
Earth's surface is always changing. Mountain, Valleys,Plains and Plateaus are some of the different land forms present on Earth. The process of carrying away materials from the Earth's Surface is called Erosion, erosion eats away Earth's surface. The main agents of erosion are water, wind, ice water, sediments and soil. Erosion works with deposition. Together they change land forms and form new ones. Flowing water wears away wood, river form gullies, ocean water break big rocks into sand and wind carries away sand.
