Unit 1 Lesson 4 Erosion and Deposition by Wind, Ice, and GravityCopyright © Houghton Mifflin Harcourt Publishing Company. How can wind shape Earth? • When wind moves soil, sand, and rock particles, it acts as an agent of erosion. • The grinding and wearing down of rock surfaces by other rock or sand particles is abrasion. • Rocks can become smooth and polished from abrasion.the grinding and wearing down of rock surfaces by other rock or sand particles,Running Water Causes Erosion — Mr. Mulroy's Earth ScienceOF ALL OF THE AGENTS OF EROSION, RUNNING WATER IS THE MOST POWERFUL. For our purposes running water includes everything from precipitation like rain and snow, streams, and rivers. When rain falls on the Earth's surface it will always move to the lowest elevation possible. Usually these trickles of rain water.
