Weathering,Erosion,Deposition and Soil
There are three types of Weathering and they are
-Physical Weathering: Is caused by the effects of changing temperature on rocks causing the rock to break apart this is sometimes assisted by water.
-Chemical Weathering: The erosion of rocks caused by chemical reactions rather than by mechanical processes
-Biological Weathering: Is the weakening of rocks by animals,plants,microbes
This rock was split as water entered its cracks and began to freeze and thaw slowly splitting the rock
The Grand Canyon was chiseled away by water from the Colorado river this is a great example of Chemical Weathering.
This picture was taken at Girraween National Park a garden of plants are growing on this rock as the roots sink into the rock it will weather it away
Erosion is the process of eroding or being eroded away by wind,water,or other natural agents.
Several landforms have been shaped by Erosion and sometimes they turn into beautiful places know all around the world. For some examples here are some places that have been affected by erosion.
`In the Vermillion Cliffs of Arizona sand has been picked up by the wind for thousand of years and scrapped against the rocks. Its has slowly chiseled it into a smooth pattern several looking like breaking waves which is how it got its name.
"The Old Man of Hoy"
Just off the west coast of Orkney Islands in Scotland stands a 450 feet high wall of rock colums formed by waves
FInally this tunnel in the rock was formed by wind and wave constantly pounding against it.

Here are some landforms shaped by Deposition
Beaches all over the world are formed from deposition from sand to rocks it builds up our beaches.
Also formed from despostion spits are formed when sand and rocks are washed in a zig zag way up the coast of a beach.
Coastal Deposition is when the sea drops or deposits material. This can include sand, sediment and shingle
it is 25% water 25% air 45% Mineral and 5% OM
Soil in the NC
A soil conservation method is changing the plants you plant each year to keep the nutrients
