PRESENTATION OUTLINE
EROSION&DEPOSITION&WEATHERING
In the bottom left corner is an example of deposition. These rocks were carried by the river and deposited at the sides of the stream.
This grass is an example of how humans control erosion. They placed fake grass over the dirt that was here, so the rain that would go into the drain that is in the next slide and not carry dirt with it.
This is an example of erosion. This trees roots are breaking through the soil, then causing the dirt to break and or fall.
Humans have also altered this area to control erosion. They use these waddles so when it rains, the soil doesn't fall through the gate.
This is another example of erosion, once again, the roots of the trees have sprouted through the dirt and caused it to break apart.
This is an example of weathering. At one point these rocks were pointed and sharp, they have been weathered down by rocks or rain to be smooth.
This picture shows erosion in progress. Water or wind has caused these sediments to fall or blow through the gate.
This tree falling on the ground is once again, an example of erosion, the tree falls, then breaking rocks and causing dirt and sediments to fall and break.
This gravestone labeled "Susie Cat" has been weathered away by either water, ice or other rocks. There are also lichen type organisms on it.
Pictured here is a layer of rocks placed to prevent erosion in this area by humans.
This is another gravestone. It is being weathered away by rust growing because of iron and water mixing. Also known as chemical weathering.
Humans have altered this area by putting a fence or boundary around the construction site to stop dirt and sediment from blowing onto the street.
