Rocks or land changes shape overtime through a process called erosion. In this video, students will learn about two main methods of erosion: wind and water erosion. When a rock or land is exposed to blowing winds or running water, small amounts of softer rocks are striped off and transported to other places. Erosion changes the shape of rock or land and sometimes gifts us with popular tourist locations such as the Wave, Arizona; Old Man of Holy, Scotland; and the Grand Canyon.
This video satisfies the 4-ESS2-1 requirement of fourth-grade science proficiency.
Students who demonstrate understanding can: 4-ESS2-1. Make observations and/or measurements to provide evidence of the effects of weathering or the rate of erosion by water, ice, wind, or vegetation.
