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