4Erosive Forces: Wind, Water, Ice, and Air [02:35] Segment DescriptionErosion is caused by water, wind, and ice. Soil erosion is a problem because wind and water can cause the loss of valuable topsoil. Soil formation is a very slow process.
5White River White River This picture was taken on 465 overlooking the White River. This was taken 3 years ago. What changes do you notice when you are driving with your parents?
6White River White River In this activity, the students are working to make sense of graph data. When they look at this they should be able to see that in may the sand bar appears to be further from the shore. Why would this be? Because there is more water in the river and that covers more of the sand bar.
7Do you see signs of Erosion Exposed tree rootsCollapsed river bankCracks in the soil in a river bankThe top part of the river bank overhangs.Clumps of grass in the riverDo you see signs of ErosionBrown or colored water
8What is the difference between Erosion and Weathering? Erosion can happen over a long period of timeWeathering happens when the rocks break up
9There are many kinds of Erosion. Here are a few:Wave ActionRunning WaterLandslidesCreepRock FallMud FlowAvalancheGlaciersSlump
10Another type of Man made erosion is Acid rain Discuss what they see. If acid rain does this to stone, what does it do to living things?toAnother type of Man made erosion is Acid rain
11Wave action is when waves hit the rocks and pieces of rock break off.
12In this picture the running water eroded the sides of this canyon and created the V-shaped valleys.
13This is a picture of a landslide. A type of mass wasting.
14In this picture the land has slumped into the road below.
15This is a diagram of creep This is a diagram of creep. The hillside slowly slips over many years from temperature or water.
16This is a picture of a glacier. How does it carve out the earth?
