Here's a breakdown:
* Creep: This is a type of mass wasting, where gravity slowly pulls soil, rock, and other debris downslope. It's a very slow process, often only moving a few centimeters or inches per year.
* Causes: Creep is caused by:
* Freezing and thawing: Water expands when it freezes, pushing soil particles apart. When it thaws, the soil particles settle, causing them to move downhill slightly.
* Wetting and drying: Similar to freezing and thawing, the expansion and contraction of soil due to wetting and drying can also cause slow downslope movement.
* Animal activity: Burrowing animals and even plant roots can disrupt the soil structure and contribute to creep.
Signs of creep:
* Tilted fence posts or trees
* Curved or bent retaining walls
* Terraced slopes
While creep is slow, it can have significant long-term impacts on the landscape, causing landslides and other forms of mass wasting over time.
