Wind & Gravity Erosion
100
occurs when water soaks into cracks in a rock and freezes; expansion of the ice as it freezes can split the rock
What is ice wedging?
100
The main agent of chemical weathering.
What is water?
100
Created by erosion beneath the earth's surface.
What are caves?
100
A thick ice sheet that slowly moves under its own weight.
What is a glacier?
100
A very slow downslope movement of soil and rock fragments.
What is soil creep?
200
The breaking or peeling away of rock in layers.
What is exfoliation?
200
The reaction of oxygen with minerals to form new compounds.
What is oxidation?
200
This is the process by which water removes a thin sheet of topsoil from the surface of land.
What is sheet erosion?
200
The part of the glacier that is moving the fastest.
What is the center (or the surface)?
200
A type of mass wasting consisting of rapid movements of loose, water-saturated soil.
What is a mudflow?
300
The piles of broken fragments at the base of a mountain.
What is talus?
300
This type of rock is very resistant to chemical weathering.
What is granite?
300
This force of erosion has the greatest effect on the earth's surface.
What is running water?
300
This is formed when a glacier overruns it old moraines.
What is a drumlin?
300
Occurs when a mass of ice and snow breaks loose from a mountain face.
What is an avalanche?
400
A park known for its exfoliation domes.
What is Yosemite National Park.
400
The acid found in rainwater and groundwater that promotes chemical weathering.
What is carbonic acid?
400
Usually a high ridge, this separates two adjoining drainage basins.
What is a drainage divide?
400
The sediment left by melting glaciers that is NOT sorted according to size.
What is till?
400
Occurs when a huge mass of rock or soil suddenly slides down a slope.
What is a landslide?
500
Mechanical weathering does not change this.
What is the chemical composition of rock?
500
Produced in soil by mosses and lichens and by decaying plants and animals.
What is acid?
500
This is one of the states with the highest occurrence of sinkholes.
What is Florida, Texas, Alabama, Missouri, or Kentucky?
500
This is formed when a large hole left from melted glacial ice fills with water.
What is a kettle lake?
500
Occurs when rock fragments break off the sides of steep cliffs.
What are rockfalls?
