Study Notes

Soil Erosion and Landforms

Soil erosion is closely linked with weathering and deposition, where tiny particles of rocks or sediments are carried away from one place to another.
Wind and water are the main factors of erosion, breaking down rocks and carrying sediments to new locations, resulting in changes to landforms over time.

Effects of Soil Erosion on Agriculture

Soil erosion can result in topsoil loss, leading to rills and gullies formation, which deplete soil fertility and erode a significant amount of soil.
The majority of plant nutrients are found in the topsoil, which is often carried away by wind and water.
Soil erosion reduces the ability of soil to absorb water, leading to dry, coarse, and unsuitable soil for vegetation.

Soil Erosion and Animals

Burrowing animals can contribute to sediment transport by carrying rocks and soil particles on their bodies.
Animals' movements can break down rocks, and their waste materials can aid in rock decay, leading to soil erosion.

Human Impact on Soil Erosion

Human activities, such as gardening, quarrying, mining, deforestation, bad farming, and kaingin, can significantly increase soil erosion rates.
Even walking can contribute to soil erosion, as soil clings to shoes and is transported from place to place.

Environmental Impacts of Soil Erosion

Soil erosion can shape Earth's landforms, but also has a negative impact on the ecosystem, especially when it occurs suddenly or abruptly.
Landslides can result from erosion, posing a significant threat to people, the environment, and properties.
Soil erosion can alter the shape and size of land, making it difficult to travel and requiring expensive repairs to roads and bridges.
