1. Erosion: This is the process of rocks being worn down and transported by natural forces like wind, water, or ice.
* Examples:
* Weathering: The breakdown of rocks in place.
* Transportation: The movement of weathered rock fragments by wind, water, or ice.
* Deposition: The settling of transported rock fragments in a new location.
2. Mass Wasting: This refers to the downward movement of rock and soil due to gravity.
* Examples:
* Landslides: Rapid movement of a mass of rock, debris, or earth down a slope.
* Creep: Slow, gradual movement of soil and rock downslope.
3. Glaciation: This involves the movement of ice sheets that can carry and deposit large quantities of rock.
* Examples:
* Glacial erosion: Ice carving out valleys and transporting rocks.
* Glacial deposition: The accumulation of rocks and sediment carried by glaciers.
4. Human activities: Rocks can also be moved by humans for various purposes, such as:
* Mining: Extraction of rocks and minerals.
* Construction: Use of rocks as building materials.
* Transportation: Movement of rocks for various purposes.
Therefore, the term used to describe the movement of rocks depends on the mechanism responsible for their displacement.
