PRESENTATION OUTLINE
Erosion
This picture shows a example of erosion. It's shows this because animals and water have created a cavity under a side walk
Erosion
This is another example of erosion. Extra water from a rain storm came down a hill to this run off. From doing this it eroded the dirt away from the concrete
Erosion
This picture of erosion demonstrates ice wedging. Ice wedging is when ice get in between the rocks cracks and freezes. This expands the crack and makes it bigger.
Erosion
In this example of erosion water is slowly dripping into soil. It erodes the soil by the water running off and Carrying dirt and sediment with it.
Erosion
One last example of erosion is water and animals digging and washing away dirt from the roots of trees and plants
This picture here is showing erosion in progress. As water runs throughout a stream it is constantly eroding the bock of cement away
This is an example of erosion control. People lay down long straw things called waddles. They let water through them while not letting dirt and sediments go through.
In this picture people lay down grass to filter any water that comes down into the run off.
In this example of erosion control a construction site puts up a black tarp fence to minimize the amount of water and debris can leave the area.
This picture of erosion control shows a layer of rocks layer down to keep out sediments from entering an area they are not supposed to be in.
This pictures is showing deposition. As a stream flow out a tunnel it deposits sediments by the side of the stream.
This is an example of chemical erosion. This is due to water mixing with chemicals used to construct the tombstone
This picture shows an example of weathering. At one point water enters a small crack in the schools wall and freezes.
This is an example of erosion. Extra water from a drainage pipe runs of into a near by pond. Over time this has created a little stream for the water to travel to the pond
