Study Notes
Loess
- Loess is a fertile soil that supports the growth of healthy crops.
Factors Affecting Runoff
- Land use influences how much water runs off an area.
- The amount of rainfall directly affects runoff levels.
- Vegetation cover can either absorb rainwater or contribute to runoff.
Glacier Formation
- Glaciers are formed through the processes of accumulation and compaction of snow.
Stalactites
- Stalactites are icicle-shaped formations found in caves, created by the deposition of minerals.
Features Created by Wave Erosion
- Erosion from waves can lead to the formation of natural arches, cliffs, and stacks along coastlines.
Mechanisms of Wave Erosion
- Back-and-forth wave movement helps loosen sediments and rocks along the coast.
- Continuous impacts from waves further erode the shoreline by loosening materials.
- Scraping of sediments against each other contributes to the wearing away of surfaces.
Formation of Waterfalls
- Waterfalls form when soft rock layers erode away, causing a drop in the water flow.
Groundwater Layers
- The water table marks the boundary between saturated and unsaturated ground.
- The saturation zone indicates the area in the ground that is fully saturated with water.
Wind Erosion Process
- Abrasion is the process where wind wears away tall sandstone rock formations.
Reducing Runoff
- Increased vegetation helps to decrease the amount of runoff in an area by enhancing water absorption.
