Sand dunes are made from sand dropping out of the wind. Is this process mainly weathering and erosion, or deposition?
Deposition

What does 'Meander' mean when we use it to describe a river?
turning, twisting, curving, bending
100
Caves are mainly made by acidic water dissolving limestone and being eroded away. What other event/landform is caused by a similar process of rock dissolving, then things falling into that space?
A sinkhole

A river delta is mainly made by what process?
Deposition

Which point here is going to experience the most deposition?
Point C

What is it called when the wind weathers something? (like a sculpted rock)
Abrasion
200
If erosion is occurring more than deposition on a beach, what will happen to the beach?
It will shrink/get smaller
200
If deposition is occurring more than erosion on a beach, what will happen to the beach?
It will get bigger/grow

What is the rock/soil/sand that glaciers carry and drop off called?
Till
300
How many peaks are present here?
2
300
What causes rivers to meander?
Both erosion and deposition.
300
Which point here is going to experience the most erosion?
Point D

Will wind or Water weather a rock faster?
Water
300
Give the definition of Deposition
Putting sediment down
300
A pile of till that is left where the glacier ends is called this.
Moraine

Two hikers are on this mountain, one is starting at point B, one is starting at point A. Which hiker is traveling along a steeper route to reach the peak at point C?
Hiker B
400
What is the term used to describe erosion and deposition caused by gravity? like landslides, avalanches, or slumps
Mass Movement
400
This image shows the formation of what landform?
An Oxbow Lake
400
How does ice cause weathering (describe the process, don't just name it)
Ice freezes in cracks or rocks and splits the rock apart
or
Glaciers wear down rocks and pick them up.
400
What will vegetation do to the rate of erosion on a landscape?
Slow/decrease
400
Wind dropping sand into piles in a desert/beach will cause this landform to form.
Dunes
400
What are these called (at Kelly's Island)
Glacial striations / Glacial Grooves
500
If you were traveling from point C to point D, what landform would you be walking through?
A Valley

Describe one way to increase erosion on a stream table.
Lift the top higher
Pour more water down
Pour the water faster
500
This rock was weathered by what?
Acid Rain / Chemical weathering
500
What agent of erosion caused the Great lakes to form?
Ice / Glaciers
500
Why is water deposited on the inside of a river bend?
The water is moving slower and sediment drops out
