PPT-EROSION BY WATER, WIND & GLACIERS

Chapter 9 Section 3 4 5 and 6 How Water Erodes Most sediment washes or falls into a river as a result of mass movement and runoff Other sediment erodes from the bottom or sides of the river Streams carry sediment in several . Methods of soil conservation (ch3). The key aspects discussed in this chapter are:. Windbreaks. Contour ploughing. Stubble planting. Terraces. Stone walls. Reduce farming in dry weather. Windbreaks.

J. Quigley. 4/2012. Water Shapes the Land. Water Shapes the Land. The Mississippi River is like a thousand dump trucks… every year it carries more than 300 million tons of sediment to the ocean! . This sediment is being washed away from the surface of the land and is called erosion.. Prairie School. Earth Science. Glaciers: Moving Ice. When you take a handful of snow and squeeze it, you are creating a product that is similar to that of glaciers. . Glacier: fast moving, large mass of ice. . Scenario #1. Flood water pounds against a canyon wall and wears it down.. Weathering. Scenario #2. Rain washing soil away from a hillside. Erosion. Scenario #3.
