Web26 apr. 2024 · Answer: attrition. Explanation: Attrition is a type of force that is present when two surfaces come into contact. An example of this can be seen when rocks carried by a river break and break into smaller pieces, this is because the river causes contact between the rock surfaces that eventually tear them apart and cause them to break.
