All About Weathering, erosion, deposition, and soil

Working together

Weathering, erosion, and deposition are the main forces behind creating the landscapes we see everyday.


  • the breaking down of rocks and other materials on Earth's surface
There are Three different types of weathering

  • Mechanical weathering
  • Chemical weathering
  • biochemical weathering

Mechanical weathering is when rock is physically broken down into smaller pieces.

Chemical weathering is the process by which rocks break down as a result of chemical reactions

Biological weathering is when rock is broken down by plants and animals


The process by which wind, water, ice, or gravity transports sediment to one area to another

Two Landforms that have been formed by erosion

  • Geo at selwicks bay

  • The Grand Canyon: formed by Colorado River

Wave cut notch at Flamborough.


Process in which sediments, soil, and rock are added to a landform or landmass

Landforms made by deposition

  • Spurn Head Spit
  • Sandbar on Lake Norman


The soil is 25% Air, 45% minerals, 25% water, and 5% OM

Soil is important because is provides support for plants and all living things need that
