100
The breakdown of rocks.
What is weathering?
100
The number one agent of erosion.
What is running water?
100
The four agents of erosion drop the rock and soil sediment that they are carrying.
What is deposition?
100
A curve in a river.
What is a meander?
100
Rain, sleet, snow and hail
What is precipitation?
200
Disintegration of rocks into smaller pieces of the same stuff.
What is mechanical weathering?
200
This type of erosion is common in a hot, dry climate.
What is wind?
200
A large deposit of sand by the wind.
What is a sand dune?
200
Running water over millions of years creates it.
What is a canyon?
200
Water turning into water vapor.
What is evaporation?
300
Decomposition of rocks into different substances.
What is chemical weathering?
300
Rocks and sediment moving down slope.
What is gravity?
300
Where most running water eventually deposits sediment.
What is the ocean floor?
300
Fan shaped deposits at the mouth of a river.
What is a delta?
300
Water vapor turning into water.
What is condensation?
400
When oxygen reacts with minerals changing them into iron oxide.
What is oxidation?
400
This agent of erosion produces U-shaped valleys.
What are valley glaciers?
400
This is where deposition occurs within a stream.
What is the inside of the curve or point bar?
400
Why the outside of the curve or cut bank is deeper.
What is because of faster water?
400
How many sides a snowflake has.
What is 6?
500
Water that has seeped into cracks in rocks will exert pressure on the rock when the temperature drops and the water changes into ice. When the ice thaws, more water enters the cracks. Repeated freezing and thawing of this water will eventually result in the rock breaking apart.
What is frost wedging?
500
In a stream this is where erosion occurs.
What is the outside curve or cut bank?
500
The erosional depositional interface.
What is the area in between the point bar and the cut bank?
500
Blue
