It reduces the soil's water absorption capacity
What is the impact of sediments washed away by water due to soil erosion?
It clogs irrigation systems
How does soil erosion impact food production?
It reduces food production for both animals and humans
How do animals contribute to sediment transport?
By breaking down rocks with their claws and hooves
Which human activity is mentioned as contributing to soil erosion in a garden?
Walking through a garden
What impact does quarrying have on the environment?
Depletion of groundwater
How do animals and humans contribute similarly to soil erosion?
Both walk, causing soil to cling to their bodies
What activity contributes to sediment build-up downstream due to the removal of rocks?
Quarrying
How does walking contribute to soil erosion for both animals and humans?
Soil sticks to shoes and gets transported
Which of the following is NOT a direct consequence of soil erosion?
Increased water quality in nearby water bodies
How does soil erosion impact travel and transportation?
It can damage roads and bridges, making travel difficult
Which of the following statements about the effects of soil erosion on landforms is correct?
Erosion can alter landforms, but changes take years to become noticeable
What is a potential personal impact of soil erosion?
Loss of life or damage to personal property from landslides
Which of the following is NOT mentioned as a human activity that intensifies soil erosion?
Reforestation
What is a potential economic impact of soil erosion mentioned in the text?
Expensive repairs for damaged roads and bridges
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.
