3-1 Changing Earth's Surface
3-2 Water Erosion
3-3 Wind and Waves
3-4 Glaciers
100
The process by which water, wind, ice, or gravity moves weathered rock or soil.
What is erosion?
100
The major agent of erosion.
What is water running downhill (or rivers/streams)?
100
This is the major force that allows waves to form?
What is wind?
100
A large mass of ice that moves slowly over land and forms when more snow falls than melts.
What is a glacier?
200
This type of mass movement causes rock and soil to rapidly separate from the main slope.
What is a slump?
200
A waterform that has been cut off from a meander.
What is an oxbow lake?
200
This is one way that wind polishes rock, but causes little erosion.
What is abrasion?
200
This is the major force that allows glaciers to move.
What is gravity?
300
This is any one of the several processes that moves sediment downhill.
What is mass movement?
300
A wide sloping deposit of sediment formed where a stream leaves a steep mountain and fans out.
What is an alluvial fan?
300
This is a part of the shore that sticks out into the ocean and are made of harder rock that resists erosion by the waves.
What is the headland?
300
The two ways in which glaciers erode at Earth's surface.
What are plucking and abrasion?
400
These are four of the five agents of erosion.
What are wind, running water, waves, glaciers, and gravity?
400
Sediment deposited where a river flows into an ocean or lake.
What is a delta?
400
The process by which wind removes surface materials and it is the main way that wind causes erosion.
What is deflation?
400
This is where a glacier deposits mounds or ridges of till.
What is a moraine?
500
This is a small depression that forms when a chunk of ice is left from a glacier.
What is a kettle or kettle lake?
500
These form where a river meets an area of rock that is very hard and erodes slowly. The river instead moves across a path of softer rock.
What are waterfalls?
500
This is a wind-deposited sediment that is finer than sand and helps to form fertile soil.
What is loess?
500
This is when a glacier melts, it deposits the sediment it eroded from the land, creating different types of landforms.
What is glacial deposition?
