River processes

Transportation in a river is ...

• ...material being deposited by a river.

• ...sediment being broken down as it is moved in different ways.

• ...sediment being moved down the river system in different ways.

Erosion in a river is ...

• ...sediment being moved down the river system in different ways

• ...sediment being broken down as it is moved in different ways.

• ...sediment being deposited on a river bed.

A form of transport in a river: Large rocks and boulders are rolled along the river bed.

A form of transport in a river: Very small particles of sand or clay that are ‘__________’ in the water. These particles will ‘settle’ if kept in a jar of water overnight and the water will look clear.

A form of transport is solution ...

• ... where large rocks and boulders are rolled along the river bed.

• ... where smaller stones are bounced along the river bed in a leap frogging motion

• ... where very small grains of sand or silt are carried along with the water

• ...where some material is dissolved and is carried downstream.

A form of transport in a river: where smaller stones are bounced along the river bed in a leap frogging motion.

 The sheer force of water hitting the banks of the river.

• Corrosion

• Hydraulic action

• Attrition

• Abrasion

Where material is moved along the bed of a river, collides with other material, and breaks up into smaller and smaller pieces.

A valley with very steep sides, found in the upper course of a river. Strong downwards erosion of the river bed causes the deep/steep shape

• A Tributary

• A gorge

• A V-shaped valley

• A U-shaped valley

A narrow valley between hills or mountains, typically with steep rocky walls and a stream or river running through it.

• A Gorge

• A V-shaped valley

• A U-shaped valley

• A watershed boundary
