100
This is the direction that streams always flow.
What is downhill?
100
This is a glacier.
What is a massive river of ice?
100
This kind of change in a river's speed causes deposition.
What is slowing down?
100
This creates sinkholes.
What is erosion from groundwater?
100
An older stream will have more of these two features than a younger stream.
What are meanders and oxbow lakes?
200
This is a smaller stream that connects to a larger stream.
What is a tributary?
200
This is the reason glaciers move/slide down the side of a mountain.
What is gravity?
200
These are groundwater depositional features found in caves.
What are stalactites and stalagmites?
200
Removing trees from a hillside might make this more likely.
What is slump/creep/mass movement/erosion by gravity?
200
This process created this shape.
What is erosion by wind?
300
When water is very close to the surface and water flows out of the ground it forms this.
What is a spring?
300
The presence of this is proof glacial deposition in New England.
What are moraines/outwash/till?
300
This is a feature created by water deposition at the mouth of a river.
What is a delta?
300
During a stream's lifetime, this is the period when it will cause the most erosion.
What is when it's young?
300
This is a feature created by wind deposition that often forms in deserts.
What is a dune?
400
A decrease in this causes the level of groundwater (the water table) to drop.
What is rain?
400
These kinds of valleys in New England prove that glaciers were present here many many years ago.
What is U-shaped?
400
This is the difference between stalactites and stalagmites.
What is stalactites grow from the ceiling and stalagmites grow from the ground?
400
Slump, creep, and other forms of erosion by gravity can be a result of this.
What is removing trees, OR digging to build houses/highways, OR earthquakes?
400
This is when sand is blown against a rock face and eventually weathers it into a new shape.
What is abrasion?
500
Water that soaks into empty spaces between rocks and soil is called this.
What is groundwater?
500
Most of the Earth's freshwater is found in this form.
What is frozen?
500
This is another name for an alluvial fan.
What is a delta?
500
Aretes and cirques are erosion caused by this.
What is a glacier?
500
This a pile of loose soil piled up by the wind
What is loess?
