What is it?
Four causes of erosion
What are water, wind, glaciers, gravity
The process that breaks rocks down into smaller pieces
What is Weathering
The process the carries away rock particles
What is Erosion
Deflation
What happens when the wind removes surface particles
Three types of mass movement caused by gravity that happen very quickly
What are landslides; mudflows; slumps
This is what happens after erosion moves (or deposits) sediment
What is Deposition
Two destructive forces
What is are weather and erosion?
When rocks get broken up without changing their chemical composition
What is mechanical weathering
Two examples of land forms that are formed by wave erosion
What are sea caves, sea arches, sea stacks
Abrasion
What happens when wind carries particles that rub or scrape against rocks
The speed of glaciers
What is verrrrrry, verrry, slow
Two examples of how wind deposition builds up earth’s surface
What are Sand dunes, Loess deposits
Constructive force
What is Deposition
When rocks break down because of changes in their chemical composition
What is Chemical weathering
This type of water erosion breaks down coastal rocks
What is Wave Erosion
These can help hold the soil in a strong wind
What are plants
Four examples of how gravity can move sediment
What are land slides, mud flows, slumps, creeps
Two examples of water deposition
What are Deltas, flood plains, sand bars, barrier islands
The earth’s spheres that are related to water and ice
What are the hydrosphere and cryosphere
Three examples of causes of mechanical weathering
What are Freeze/thaw; plant growth; actions of animals; human activities; abrasion; release of pressure
Moving water causes this
What is run off
These are created when sand builds up after strong winds blow
What are sand dunes
When a glacier picks up rocks as it moves over the land
What is Plucking
The water deposits that look like icicles hanging down from the top of caves and or building up from the bottom of caves.
What are Stalactites and stalagmites
These land forms interact with the cryosphere, geosphere AND hydrosphere
What are Glaciers
Three elements that cause chemical weathering
What are water, oxygen, carbon dioxide, living organisms, acid rain
This type of water creates erosion by chemical weathering underground
What is Groundwater
Loess deposits
What are the organic particles that have been deposited by the wind that result in fertile soil
When a glaciers drags rocks across the land.
What is Abrasion
Tills, moraines and kettles
What are New land forms that glaciers cause by their slow movement over land
