Question	Ans.	Explanation
9210	C	Sediments are the product of a river basin system.
9417	C
9223	C	There is a negative relationship between the slope gradient and infiltration rate.
9515	B	X is evaporation.
9925	D	There are only 2 main routes for rainwater reaching the ground surface: infiltration and runoff. Therefore, these two should have a negative relationship.
9317	C
9216	B	The steepness of the slope can only affect the velocity of the river.
9726	D	S has the fastest flow because it has the least friction.
9215	C	The volume of the flow in upper course should be lower because it has fewer tributaries.
9416	C	X is the concave back of meander while Y is the convex bank.
9506	C	The sediment load should be the greatest in the lower course.

9525	B	Potholes are mainly formed by abrasion.
9612	B	The base of the waterfall is also cut. This shows that the base is also made up of less resistant rocks.
9921	C
9923	B	Prevailing wind can only increase the erosive power of waves.
9922	B
