What is a sandbar that sticks up above the water and is connected to the shoreline?
A long narrow island that forms parallel to the shoreline is called
What do continental glaciers do to the land they pass over?
They flatten and smooth the land
What do alpine glaciers do to the land they move through?
They create sharp, rugged landscapes
What are two (2) ways glaciers can move?
SLIDE on land and FLOAT on water
What is formed when waves cut completely through the rock in a sea cave?
What is a large hole in a weak rock near a sea cliff called?
A depression scooped out by the wind in the desert is called (type of deflation)?
What is a rock surface consisting of pebbles and small broken rocks left behind after finer material has blown away called (type of deflation)?
What is the most common type of landslide?
What is the steepest angle at which loose material will
slide down a slope?
Angle of repose
What type of glacier forms in a mountainous area?
Dunes usually move in what direction?
Same direction the wind is blowing
What kind of pattern does a longshore current make?
What do waves make when they break rock into smaller pieces?
A landform created by offshore deposits which is made up of sand, gravel and shells is called
What kind of landscape feature might have been carved by a glacier to form a waterfall?
The wearing away of rock surfaces by other rock or sand is called
The skipping and bouncing of small particles in the direction that the wind is blowing is called
What is an example of a till deposit?
Why are some areas more affected by wind erosion than others?
Some areas are not covered with plants/vegetation so the sediment/soil is easily blown away (i.e., deserts and shorelines)
Describe how dunes form
1st barriers slow down the wind which deposits sand. Next, sand builds up over time becoming a mound of sand which becomes a dune
What is the difference between erosion and deposition?
Erosion is the removeal/wearing away of material/sediment
Deposition is the addition of sediment to an area
A place where land and water meet is called
Waves in a wave train are separated by a period of time called
The flow of a large amount of mud or rock and soil mixed with water is called
The slow downhill movement of rock material is called
A group of loose rocks falling down a slope is called
The sudden rapid movement of rock and soil down a slope is called
The blowing of millions of sharp sand grains that erod, smooth and polish rocks is called
Mounds of sand deposited by the wind are called
The process in which wind blows away soil is called
Identify the 3 step process of glacial formation
1. snow builds up year after year
2. top layer pushes down on lower layer (becomes more dense/compact)
3. bottom layer turns to ice and movement begins
The movement of any section of land down a slope is called
What is an example of stratified drift?
Thick deposits of windblown, fine-graines sediment that are carried great distances are called
Name the 5 types of mass movement
a type of rapid mass movement?
What is the steep side of a dune called?
