Geomorphic Processes Flashcards
What is erosion?
Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water.
What is deposition?
Deposition is the laying down of sediment carried by wind, flowing water, the sea or ice.
It is, in simple terms, the settling of sediment.
What is weathering?
Weathering describes the breaking down or dissolving of rocks and minerals on the surface of Earth.
What is an example of erosion?
On a rainy day, you might see small streams of water cutting paths down a hill. This movement of soil and rock by water is an example of erosion.
What is an example of deposition?
One example of deposition is the process by which, in sub-freezing air, water vapour changes directly to ice without first becoming a liquid.
What is an example of weathering?
When the ice melts, more water can get into the larger crack; if it freezes again it expands and can make the crack even bigger.
