Bust a move What is Erosion Erosion is defined as removal of rocks and soil by wind water ice and gravity Wind water ice and gravity are also known as the agents of erosion Weathering vs Erosion . in Poland. This project has been funded with support from the European Commission.. This publication reflects the views only of the author, and the . Commision. cannot be held responsible for any use which may be of the information contained therein.. Rain . Splash. Sheet. Rill. Gully . 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.. Water Erosion. How Does Moving Water Cause Erosion?. Erosion by water begins with a splash of rain.. Some rainfall sinks into the ground.. Some evaporates or is taken up by plants.. The rest of the water runs off over the land surface.. another.. 2 . kinds:. 1) . Rill erosion. is the erosion by running water in small channels. , on the side of a slope.. 2) . Gully erosion. is when a rill channel evolves to become deep and wide.. .

Wind, water, ice and gravity are also known as the agents of erosion.. Weathering vs. Erosion . Weathering involves two processes . EROSION: surface and rock materials by wind, water, and other materials. The normal rate of erosion can be quickened by mass wasting, fluvial entrainment, surface erosion, freeze - thaw movement WHAT IS COASTAL EROSION? Coastal erosion is the endless reshaping of shorelines by waves, currents, tides, storms, ice, rain and groundwater seepage. Human activities, like construction, dredging, CO The creation of sedimentary rocks. Weathering and Mass Movement. Objectives:. 1. Describe the processes by which erosion wears down and carries away rock. 2. Distinguish between chemical and mechanical weathering. Move through the power point . in your own time.
