Miscellaneous
100
This is the general process by which rocks and minerals are broken down into smaller pieces called sediments.
What is weathering?
100
This process involves the transportation of weathered materials from one location to another by agents like water, ice, wind, or gravity
What is erosion?
100
Glaciers transform V-shaped river valleys into this specific shape as they erode the landscape
What is a U-shaped valley?
100
This is the process by which sediments are released or "dropped" by their transporting agents
What is deposition?
100
In a situation where larger particles settle on the bottom and smaller particles settle toward the top, it is known as this
What is vertical sorting?
200
This type of weathering involves the physical breakdown of rocks into smaller fragments without changing their chemical composition
What is mechanical (physical) weathering?
200
This agent of erosion is responsible for the formation of V-shaped valleys
What is running water?
200
These parallel scratches in bedrock are created as a glacier carries rocks across the land
What are glacial striations?
200
Deposition is primarily caused by this change in the agent of erosion
What is slowing down?
200
According to this graph, if a stream is flowing at 100 cm/s, this is the largest diameter particle it can transport
What is 1.0 cm?
300
This specific mechanical process occurs when water seeps into cracks in a rock, freezes, and expands to break the rock apart
What is frost wedging?
300
These two forces are involved in all mass movements
What is gravity and friction?
300
Wind erosion is most common in these types of areas where there is little to no vegetation
What are dry areas (or deserts/recently plowed farmland)?
300
Most deposition occurs in these types of water bodies.
What are standing or still bodies of water? Lakes, oceans
300
This mineral is often more resistant to weathering, allowing it to stick out and form steep cliffs
What is dolostone?
400
Chemical weathering is most likely to occur rapidly in this type of climate
What is warm and humid?
400
This extremely slow downhill movement of rock and soil is a type of mass movement
What is creep?
400
This historic 1930s environmental disaster in the United States was a direct result of severe wind erosion
What was the Dust Bowl?
400
On a curving (meandering) river, deposition normally occurs in this location
What is inside the curve?
400
Cleopatra’s Needle lasted for centuries in Egypt but was quickly damaged in NYC due to this type of precipitation
What is acid rain?
500
This chemical process involves the reaction of minerals with oxygen, often causing iron-rich rocks to turn a reddish color
What is oxidation?
500
This specific process must occur before erosion can happen
What is weathering?
500
Glaciers can carve these bowl-shaped depressions along mountainsides
What are cirques?
500
This type of sorting occurs when a stream enters a still body of water slowly, leaving larger particles closer to the shore
What is horizontal sorting?
500
The rate at which particles are deposited by a stream is least affected by this stream characteristic
What is the stream's elevation above sea level?
