Which term describes the material being carried by the river that hits the sides and bed of the channel?

• Abrasion

• Attrition

• Hydraulic action

• Corrosion

What happens during attrition in river erosion?

• Rocks and stones bang against each other, chipping bits off

• The force of water pushes into cracks in the rock

• Rocks are dissolved in the river water

• Material is carried along fine, light particles

What is corrosion in the context of river erosion?

• Rocks such as chalk and limestone are dissolved in the river water
