1

What is deposition?

Process by which eroded material is dropped.

2

What is Gradient?

The measure of change in elevation over a certain distance

3

What is a load?

Materials carried by a stream.

4

What is discharge?

The amount of water that a stream carries in a given amount of time.

5

What is a path that a stream follows?

Channel

6

What is a floodplain?

Many layers of deposited sediment that forms a flat area.

7

What is a meander?

Curves and bends that form a twisting, looping pattern in a stream channel.

8

What is a delta?

A fan-shaped pattern that streams deposit their loads.

9

What is an alluvial fan?

A fan-shaped deposit that forms on dry land.

10

What is water that is located within the rocks below earth's surface?

Groundwater

11

What is a place where land and a body of water meet?

Shoreline

12

First parts of a shoreline that waves meet is what?

Headlands

13

When water travels almost parallel to the shoreline very near shore what is the current called?

Longshore current

14

What forms when waves erode and undercut rock to make steep slopes?

A Sea Cliff

15

As a sea cliff erodes above the waterline, a bench of rock usually remains beneath the water at the cliff's base. What is this bench called?

Wave-cut platform.

16

Waves can cut deeply into the cracks and form large holes. As the holes continue to erode they become what?

Sea caves.
