Weathering & Erosion Flash Cards
What is Erosion??
Erosion is a deconstructive force in which sediments are moved by water, wind, or moving ice.
What is Weathering??
Weathering is a deconstructive force that breaks down rocks into smaller pieces.
What is Deposition??
Deposition is a constructive force in which sentiments that have been moved from one place and dropped or released in another place.
What is a Delta??
A delta is an island formed at the mouth of a river.
Give examples of Weathering & Erosion
Examples:
Explain the difference between chemical and mechanical Erosion
Chemical Erosion uses acids.
Mechanical erosion uses natural sources to erode items.
Give examples of Erosion
Examples:
What type of weathering does water, wind, & ice effect??
Mechanical Weathering
What type of weathering does acid rain, & rust cause??
Chemical Weathering
How does water erode the earth’s surface??
Waves chip sediments off of the earth’s surface.
How does wind effect erosion??
Wind carries sediments away
How does ice effect erosion??
Ice causes erosion by moving glaciers, which carry sediments and drops the sediments when it’s melting.
List fast changes & slow changes during the process of weathering & erosion
Fast Changes-landslides, sinkholes, etc. Slow Changes-caves, canyons, etc.
Define Crust
The thin/rocky layer of the earth’s surface
Define topographic map
A map that shows the shape of the surface features & their elevations
