Erosional Landforms
Depositional Landforms
Weathering
Erosion
Changes in Energy
100
This landform is created when limestone rock layers are dissolved by groundwater.
Limetone Caves/Caverns
100
These are large mountains of sand sized particles that are deposited and migrate via the wind
What are Dunes?
100
The physical breakdown of rock into smaller pieces
What is mechanical weathering?
100
This agent of change creates most of the landforms on Earth's surface.
What is water?
100
What has to happen to the energy of river for a delta to form?
Energy decreases
200
These flat topped mountains are taller than they are wide.
What is a Butte?
200
These are triangular areas of sediment are deposited when a river meets an ocean or a lake.
What is a delta?
200
This agent of change weathers landforms the fastest and most dramatically.
What is water
200
This agent of change can transport very large particles, even though it moves very slowly.
What are glaciers/glacial ice?
200
Which agent of change has the greatest energy:
Thunder and Lightning
Floodwaters
Strong Winds
Floodwaters
300
These form when caves collapse exposing them to the surface.
What is a sinkhole?
300
These are usually large boulders that do not match the surrounding rock types deposited by glaciers.
What are erratics?
300
Weathering results in increased surface area, which allows for weathering of a larger area. What kind of feedback loop does this illustrate?
Positive Feedback Loop
300
What is the largest size particle that wind can typically erode?
Sand
300
What is a Jetty preventing?
Beach erosion
400
These are slowly weathered into cliff faces by either wind or waves.
What are Arches?
400
Madison, WI sits on this kind of depositional landform.
What is an isthmus?
400
This acid is created when water dissolves limestone
What is Carbonic Acid?
400
Barrier Islands are deposits of sand that gather parallel to a shore line. How would a barrier island affect the wave erosion that happens on the shoreline?
Decreases erosion
400
At which number(s) is/are deposition occuring?
1 & 4
500
These are extremely sharp mountain ridges that have been carved out by glacial movement.
What is an arete?
500
Which letter(s) is/are associated with moraine(s)?
C and D
500
This climate variable has the greatest impact on rate of weathering. The more of this, the faster weathering will occur.
What is humidity
500
Sorting describes the degree to which sediment sizes are mixed. Well sorted sediment is a single size and poorly sorted sediment has lots of sizes mixed together. Which agent of change would produce the most poorly sorted sediment?
Glaciers
500
This happens when a glacier experiences snow falling in the accumulation zone that is equal to the melting in the ablation zone
What is Equilibrium?
