Weathering and Erosion Flashcards
The process of breaking down rock
Weathering
Types of weathering:
Mechanical and Chemical
The process of breaking down rocks into smaller pieces
Mechanical weathering
Frost wedging, frost heaving, pressure release, exfoliation, abrasion, hoodoo
Mechanical weathering
Oxidation, reaction of acids, lichens and mosses
Chemical weathering
Changes the rock into a different substance
Chemical weathering
Limestone caves and caverns are formed by:
Chemical weathering
Stalactites, stalagmites, columns
Cave formations
People who enjoy exploring caves
Spelunkers
When weathered material moves from one location to another
Erosion
When wind, water, or ice drops sediments and rocks in a new location
Deposition
As the rain washes across the surface of the earth, it carries sediment into streams
Stream erosion
As the rocks weather and erode, the ocean waves move the sediment to new locations
Wave erosion
Strong wind can carry tons of sediment at a time
Wind erosion
When glaciers erode huge amounts of all kinds of sediments and rocks
Ice erosion
