WEATHERING EROSION DEPOSITION SOIL

WEATHERING

Weathering is the breaking down of rocks.


Physical weathering: When rocks are broken into smaller pieces, but the chemical composition of the rock does not change.


Chemical weathering: When rocks are broken down by a chemical change. It depends on the type of rock. Acid and rain are big contributors to the change.


Biological weathering: When rocks are worn away by living organisms. This could happen if a tree root breaks through the ground, for example.

EROSION

Erosion: The process of wind, water, or ice moving rocks, soil, and sediments from oe location to another.

DEPOSITION & LANDFORMS: BEACHES

Beaches are formed by deposition. Waves take sediments and carry them to the shore. Once these sediments are deposited over and over in the same place, a beach is formed. This is a beach in Ocean Isle, North Carolina.

DEPOSITION & LANDFORMS: SPITS

Longshore drifts move sediments and material along a coastline. If the waves are not as destructive or where there is less power hitting the coast, material is deposited. When rivers meet the ocean, deposition happens. The materials deposited build up over time to form a ridge of material. This ridge is called a spit. The one below is in Spurn Point.

SOIL IN NORTH CAROLINA

Soil is used to help plants grow, it helps gas exchanges happen between the land and air, gives a habitat for animals, holds and cleans waters, helps with building construction structures, and recycling nutrients.


Soil is important in North Carolina because North Carolina is a farming state. We need nutrient-rich soil for the crops we grow to be healthy. North Carolina isn't the only place where soil is important because soil is important to every place.


There are 3 main types of soil found in North Carolina. They are cecil soil, sand hill soil, and organic soil.

SOIL CONSERVATION

Crop rotation is a form of soil conservation. Crop rotation is where you change the crops being used on a piece of land over time so the same nutrients aren't being extracted from the soil. This can also add nutrients into the soil. Such as one year you can plant strawberries, and the next year you can plant peanuts.
