Soil Formation and Composition Section 7-2
Dirt Excrement Filthy or soiling substance Something worthless Synonyms: filth, dust, grime, muck
Soil The loose upper layer of the Earth’s crust in which plants can grow
We do NOT say “Dirt”, We say “SOIL” !!!
Where does soil come from? Weathered Rock + other stuff Soil
Bedrock The solid rock in Earth’s crust When exposed at the surface, it weathers into smaller and smaller pieces to become soil
Bedrock weathers to Rock Particles
What is the “other stuff?” 2. Humus 3. Air 4. Water
Humus The organic part of soil Formed from decomposed organisms dark-colored Rich in nutrients
Loam Loam is the BEST kind of soil. Loam has a good balance of air and water, and holds LOTS of nutrients. Loam contains equal parts of Sand (drainage) Silt Clay (holds water)
Soil Horizons O = litter A = topsoil B = subsoil C = parent material bedrock
