Water On The Land

Front 1

Attrition

Back 1

Rocks get smaller when knocked together.

Front 2

Abrasion

Back 2

Erosion by pebbles wearing away the bed and banks of the river channel

Front 3

Channel

Back 3

Where the river flows

Front 4

Corrosion

Back 4

Erosion by by chemical action- chalk, limestone

Front 5

Deposition

Back 5

The process where the river no longer has the energy to carry its load

Front 6

Erosion

Back 6

The wearing away of the bed and banks of the river channel

Front 7

Gorge

Back 7

A narrow, steep-sided valley.

Front 8

Hydraulic action

Back 8

The force of the water erodes the bed and banks

Front 9

Lateral erosion

Back 9

Eroding against the banks of a river.

Front 10

Lower course

Back 10

Lower part of the river that has high volume and large discharge

Front 14

Plunge pool

Back 14

Base of a waterfall, where the water lands.

Front 15

Saltation

Back 15

Smaller pebbles are bounced along the river bed, picked up and then dropped.

Front 16

Slip-off slope

Back 16

Created on the inside of a meander from slow-flowing water

Front 17

Solution

Back 17

Minerals, such as limestone and chalk, are dissolved in the water and carried along in the flow.

Front 18

Source

Back 18

Where a river begins.

Front 19

Suspension

Back 19

The finer sand and silt-sized particles are carried along in the flow.
