What are the three processes that occur as a river flows from its source to the mouth?

• erosion, attrition and abrasion

• erosion, transportation and deposition

• erosion, transportation and solution

• erosion, attrition and corrosion

There are four main types of erosion for rivers. Which answer is correct.

• Hydraulic Action, Attrition, Rubbing, Silting
• Hydraulic Action, Abrasion, Deposition, Solution
• Hydraulic Action, Abrasion, Silting, Solution
• Hydraulic Action, Solution, Abrasion, Attrition

Attrition is when ..

• large rocks smash against each other.

• small rocks rub against the river bed.

• sand and other fine particles float.

• water flows into the rocks.

"When rocks scrape along the river bank and bed" is what type of erosion?

• Attrition
• Abrasion
• Solution
