ALL ABOUT IT!
MECHANICAL WEATHERING VS. CHEMICAL WEATHERING
SOIL FACTS - SOIL COMPOSITION, SOIL TEXTURE, AND SOIL HORIZONS
Soil texture: Soil can be made up of numbers of things small pebbles, warn down rocks and minerals, and silt particles. It all depends on the weathering and were you live. If were you live is windy and hot and cold hot and cold all the time the particles in the soil will be different than a place with no wind and a constant temperature.
Soil horizons: The soil is made up of 3 layers. These all depend on the texture of sand above it and below it. The first layer is called horizon A/ top soil. It is made up of crumbly dark brown of mixture humus, clay and many other minerals. Horizon B is made up of clay and other particles washed down from horizon A. Horizon C is mainly made up of particles withered down from the other horizons.
