Study Notes
Weathering and Rock Types
- Weathering is the chemical breakdown process of rocks.
- Parent material of peat consists of remains of dead plants and animals.
- Granite is an igneous rock formed from the cooling of magma below ground.
- Basalt is another igneous rock commonly found in volcanic activity.
- Limestone serves as the primary mineral source for calcium carbonate.
Sedimentary and Metamorphic Rocks
- Sedimentary rocks are formed through processes of erosion and deposition.
- Sandstone is a type of sedimentary rock composed of sand-sized grains.
- Marble is the metamorphic rock that originates from limestone.
- Slate is a metamorphic rock formed from shale.
Soil Characteristics and Formation
- Soil characteristics include texture, pH, and drainage.
- Young soil obtains fertility from rock minerals and organic matter; old soil relies mainly on organic matter.
- Forests contribute significantly to soil nutrient holding capacity due to trees' ability to retain nutrients.
- Topography influences soil formation, particularly affecting erosion rates.
- Availability of parent material is critical; young soil has abundant parent material, whereas old soil has diminished availability.
- Grassland ecosystems exhibit a lower nutrient holding capacity compared to forests.
Impact of Soil Erosion
- Soil erosion negatively affects fertility by removing nutrient-rich topsoil, which is vital for plant growth.
