What is sediment?
These are curves or bends in a streambed.
What is meander?
Cracks in rocks widen when water freezes inside them.
What is water weathering?

What is physical weathering?
When sediment drops out of the water and settles to the bottom, this occurs.
What is deposition?
A broad, flat area around a stream that experiences occasional flooding.
What is a floodplain?
Rocks crumble when the iron in them reacts with oxygen.
What is oxidation?

What is an alluvial fan?
Moss growing on a rock causes the rock to crack and break.
What is vegetation weathering?
This term describes the process where rocks break down, react to other substances, and are weakened.
What is chemical weathering?
Out of clay, sand, or gravel, this material settles the fastest due to its weight.
What is gravel or sand?
These are long narrow islands that lie close to the mainland, which protects the mainland from erosion.
What are barrier islands?
Weathering from extreme hot and cold temperatures.
What is temperature weathering?
