Here's a breakdown:
* Breakdown: This refers to the process of weathering, which is the breaking down of rocks, soil, and minerals through physical, chemical, or biological processes. Examples include:
* Physical weathering: Freezing and thawing of water, abrasion by wind or water, root growth
* Chemical weathering: Acid rain, oxidation, hydrolysis
* Biological weathering: Plant roots, burrowing animals
* Transportation: Once the rock and soil have been broken down, they are then transported away from their original location by various agents like:
* Wind: Carries dust, sand, and silt
* Water: Rivers, streams, ocean currents carry sediments
* Ice: Glaciers carve out valleys and transport rocks and sediment
* Gravity: Causes landslides and rockfalls
Erosion is a natural process that shapes the Earth's surface. However, human activities can accelerate erosion, leading to soil degradation, landslides, and other environmental problems.
