Which of the following are types of erosion?

• Hydraulic action, abrasion, solution and longshore drift

• Hydraulic action, abrasion, solution and suspension

• Hydraulic action, abrasion, solution and attrition

• Hydraulic action, abrasion, solution and traction

What is hydraulic action?

• Boulders and stones wearing away the river banks and bed

• Sediment particles knock against the bed or each other and become smaller and more rounded

• Fast-flowing water hits the bed and banks and forces water and air into cracks in the bedrock. The repeated changes in air pressure cause the river bed to weaken

• Acidic water dissolves rocks such as chalk or limestone

What is attrition?
