Rocks
Weathering
- Weathering is the breaking down of rocks.
- The three types of weathering are :
- Chemical - the breaking down of rocks caused by chemical interactions.
- Physical - the breaking down of rocks caused by temperature.
- Biological - the weakening of rocks by plant growth.
Chemical Weathering
This formation of rocks was weathered by Carbonation mixing with water to form holes in the rock, making it break apart.
Physical Weathering
Heat caused this rock to overheat and break apart.
Biological Weathering
A tree has grown in the middle of the rocks and has caused them to break apart to make way for the tree.
Erosion
- Erosion is the moving of the broken down rock.
The Grand Canyon
The Grand Canyon was eroded by water that moved through and caused pieces of rock to be moved until there was a dip, causing the canyon.
Arizona Rock Formations
Winds going through the Grand Canyon have eroded the sandstone to form in an anvil-type shape.
Deserts
Deserts are formed by wind moving sand/sediments and placing them together.
Deltas
Deltas are formed by water moving dirt/sediments to the end of a river or stream and dropping them off there.
Soil
- Soil consists of anything in the top two layers of the Earth's surface.
- Farmers use soil to grow plants that produce food. The nutrients give the plants a chance to grow to be used for food and anything else that can be farmed.
- The soil that is found in North Carolina is Cecil soil which is high in nutrients and it is capable of growing many different things such as corn, grain, cotton, and tobacco.
- There are a lot of different ideas for soil conservation but the one I think is most effective is crop rotation. This is when farmers switch up the crops that they plant and alternate to bring back nutrients and add a few more.
Soil Layers
The soil is made of minerals, rock, sand, clay, and silt. These also include water, air, and organic material, which is mostly matter from dead plants and animals.

My name is Anna Walker, I'm in Honors Earth and Environmental Science, Period 2. I have absolutely no idea what to write in this thing so I'm just gonna leave it at that.
