Chemical Weathering vs Mechanical Weathering
Mechanical Weathering - breaks rocks into smaller pieces, when water freezes in a rock it causes a crack is called ice wedging, top layers of rocks crack and flake of is called release of pressure.
Soil Texture - Sandy or silty soils are light soils. Soil rich in clay are heavier and hold together more tightly.
Soil Horizons - Each lower layer of soil is little less weathered then the layer above. Soil horizons are different layers of soils with depth.
What Affects The Rate of Soil?
What is Remote Sensing and how is it used to study humans impact on soil/Earth?
Importance of Soil
Common Misuses of Soil and the Negative Consequences
Not giving the soil enough nutrients -> soil cracks and becomes dry and not able to grow crops.
