Weathering,Erosion,Deposition and Soil

Weathering

Weathering is the wearing away or change the appearance or texture of (something) by long exposure to the air.

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

Erosion

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.

Deposition

Deposition is the geological process in which sediments, soil and rocks are added to a landform or land mass.

Here are some landforms shaped by Deposition

Soil Composition

Soil Composition is an important aspect of nutrient management. While soil minerals and organic matter hold and store nutrients, soil water is what readily provides nutrients for plant uptake.


it is 25% water 25% air 45% Mineral and 5% OM

Soil in the NC

Soil in important in the NC as it is used for farming and other things the type of soil found in NC is Red clay and Clay Loam


A soil conservation method is changing the plants you plant each year to keep the nutrients
