Study Notes
Earth Movement Processes
- Denudation: wear away and removal of the Earth's surface by natural forces such as weathering, erosion, and transportation
- Diastrophism: deformation of the Earth's crust, resulting in the formation of mountains, plateaus, and other landforms
- Weathering: breakdown of rocks into smaller fragments through mechanical and chemical means
Landform Formation Processes
- Volcanic activity: formation of landforms such as volcanoes, lava plateau, and volcanic islands through the eruption of magma and lava
- Tectonic plate movement: formation of mountains, plateaus, and other landforms through the movement of the Earth's crust
- Fluvial processes: formation of landforms such as deltas, canyons, and waterfalls through the action of running water
Soil Horizons
- O horizon: organic layer composed of decomposed plant and animal matter
- A horizon: topsoil layer composed of humus, mineral particles, and microorganisms
- B horizon: subsoil layer composed of minerals, clay, and other materials
- C horizon: parent material layer composed of bedrock or unweathered mineral deposits
- R horizon: bedrock layer composed of unbroken, solid rock
