River Processes

The diagram shows the river process of erosion. In a fast-flowing rive, water is forced into cracks in the bank. Over time this breaks the bank up. It is called _______________ .

• Attrition

• Hydraulic action

• Solution

• Abrasion

In the process of river transport, when small stones and pebbles are leaped or skipped along by the river current, this is called _____________ .

• Suspension

• Solution

• Saltation

• Traction

In the last river process of deposition, boulders, cobbles, pebbles, sand, silt and clay are deposited in that order because ____________________

• it is in alphabetical order, and they have to follow their turn when getting of the river transporter.

• bigger stones are less heavy than smaller pebbles

• the river transporter has had enough of these hard cases.

• the heaviest material are deposited out first, followed by the less heavy material and lastly the lightest material.

Looking at the long profile of the river's course, where does most erosion occur?

• Upper course

• Middle course

• Lower course

• The mouth

Looking at the river process of transport, when soluble material and minerals are dissolved into the water and carried along, this is called _______________ .

• Saltation

• Solution

• Traction

• Suspension

In the river process of erosion, when rocks and stones in the water act like sandpaper and scrape the river bed and bank, wearing them away, this is called ____________ .

• Solution

• Attrition

• Hydraulic action

• Abrasion

In which part of the river does water flow the fastest?

• Upper course

• Middle course

• Lower course

What name is given to the bottom of the river?

• River Bank

• River Bed

• Delta

When rocks bang together becoming rounder, smaller  and smoother.

• Hydraulic Action
• Attrition
• Abrasion
• Corrosion

Which of these is the odd one out?

• Traction
• Saltation
• Suspension
• Abrasion
