What geologic feature is this?
Cirque
Arete

How does a cirque form
When the head of a glacier plucks and erodes rock leaving behind the start of a valley
When glacier erode 3 or more aretes leaving behind a shaped edge peak.
formed when the lower valley has a greater rate of erosion than an upper cashing two valleys formed with a drop in elevation between.
It is typically formed when two glaciers erode parallel U-shaped valleys.

What type of coastline is this?
Submergent
Emergent
What will be different between a submergent and emergent coastline?
Submergent coastline has steep cliffs where the land uplifted high above water
Emergent coastline has steep cliffs where the land uplifted high above water.
Submergent coastline are flat and water seems to be taking over the land as sea levels rise.
emergent coastlines are flat and water seems to be taking over the land as sea levels rise.

Horn
How does this form?
It is typically formed when two glaciers erode parallel U-shaped valleys.
It generally results from erosion beneath the bergschrund (head) of a glacier.
when the lower valley has a greater rate of erosion than an upper cashing two valleys formed with a drop in elevation between
glaciers erode three or more arêtes, usually forming a sharp-edged peak.
Where would you expect a U shaped and V shaped Valley to form?

How does this lake form?
These lakes may form when end moraines, particularly a series of recessional moraines, dam meltwater flowing out from a glacier.
buried block of ice, left behind by a retreating glacier, melts.
when a wide meander of a river is cut off, creating a free-standing body of water.
glaciers eroded bedrock, carving basins that are now filled with rainwater.

Both are sorted
What feature is this?
Delta
Esker
Valley
Floodplain
What feature is this?
Arete
Hanging Valley
Esker
Horn
How does this feature form?
glaciers erode three or more arêtes, usually forming a sharp-edged peak.
can be formed when the lower valley has a greater rate of erosion than an upper cashing two valleys formed with a drop in elevation between.
formed within ice-walled tunnels by streams that flowed within and under glaciers.
form as a result of the movement and resulting stress associated with the shear stress generated when two semi-rigid pieces above a plastic substrate have different rates of movement
What type of lakes are these?
Kettle
Scored
Paternoster
How does a Kettle Lake form?
These lakes may form when end moraines, particularly a series of recessional moraines, dam meltwater flowing out from a glacier.
formed when glaciers eroded bedrock, carving basins that are now filled with rainwater.
abrasion and plucking of bedrock on the bottom of a cirque.
when a buried block of ice, left behind by a retreating glacier, melts.
What type of lake are the Great Lakes considered?

What type of lake is this?
Kettle
Tarn
Scorned
Paternoster
How do you know this is a tarn lake?
The lake is in a floodplain
The lake is in a cirque
The lake is in an outwash plain
The lake is connected to other lakes by a river
What feature is this?
Kettle Lake
Sinkhole
Tarn Lake
how do you know this is a sink hole?
The topo lines show they going down in elevation to the water
The topo lines show they are staying flat by the water
The topo lines show they are going up to the water
What type of moraine is this?
Medial
Lateral
Terminal
What type of moraine is this?
Medial
Lateral
Terminal (end)
how is a moraine formed?
Glaciers cutting deep into the bedrock
formed within ice-walled tunnels by streams that flowed within and under glaciers.
debris that has accumulated by plucking and abrasion from a glacier
What is the difference between glacial outwash and till?
Outwash is formed by running water, Till is formed by motion of glaciers
Outwash is formed by motion of glaciers, till is formed by running water
Both are formed by running water
Both are formed by glaciers
