Heavy . rains in northwest Iowa washed away soil, leaving this scarred tableau. This type of erosion, termed sheet-and-rill erosion, occurs when there is insufficient vegetation to hold soil in place. As rain falls, it forms sheets of surface water that transport soil away. As more water accumulates, it forms runoff channels called rills, which further displace soil.. Chapter 4.1. Pages 118-127. Key Questions. How does moving water cause erosion?. What land features are formed by water erosion and deposition?. Moving water is the major agent of the erosion that has shaped Earth’s land surface.. Physical Weathering.
