What is before?

The process in which fast moving water can slow down and adds earth sediment to a new location.
What is deposition?
100

What is a meander?
200
When water travels over a less steep slope, its speed __________________ (increases or decreases)

A deposit near the mouth of a river.
What is a delta?
300
The main force behind erosion.
What is gravity?
300
Flat land near a river formed by deposition during floods.
What is a floodplain?
300
The lines on a topographic map which show changes in elevation.
What are contour lines?
300
The building of a dam changes the flow of a river in this way.
What is the dam slows down the flow of a river?
400
A crescent shaped lake formed when a river cuts off a look to form a more direct path.

What is an alluvial fan?
500
The location along a river where erosion is likely to be the greatest.
What is at the place with the fastest flow?
500
The word used to describe deltas and floodplains because sediment is deposited in these areas making them good for farming.
What is fertile?
500
