Answers
Explanation:
7- Erosion is the process that wears away the river bed and banks. Abrasion - When pebbles grind along the river bank and bed in a sand-papering effect. Attrition - When rocks that the river is carrying knock against each.
8-A concurrent process called lateral erosion refers to the widening of a stream channel or valley. When a stream is high above its base level, downcutting will take place faster than lateral erosion; but as the level of the stream approaches its base level, the rate of lateral erosion increases.
