Answers to CE MC Questions (1992-2000)

COAST

Question	Ans.	Explanation
0029	A	The diagram shows that swash is greater than backwash. Therefore, it should be a constructive eave. Breaking wave also occurs as the wave cannot complete its oscillation in shallow water.
9414	A
9815	A	The increase in load may only reduce the wave energy.
9511	B
9412	B	X is a wave-cut platform. It is an erosional coastal feature.
9616	C	The picture is showing a geo in Shek O.
9617	D
9819	-	This item was deleted in exam.
9928	C	Stack is usually formed in a headland with concentrated energy on both sides of the headland.
9522	B	The photo is showing Po Bin Chau in Sai Kung.
9213	A	With strong prevailing wind, only erosional features can be formed on the islands.
9810	B	T is not easily eroded because it is a resistant rock while R has a sheltered location.
9715	B	A geo is an erosional coastal feature. It is formed in areas with lines of weakness.
9214	D	(1) and (2) are factors favouring wave deposition.
9413	D
9309	D
9510	C	X can extend and become attached to the other side of the coast. It encloses the sheltered bay and a bar is formed.
9310	C	When backwash is stronger than swash, destructive wave is formed. It favours erosion.
9725	A	Long fetch only favours wave erosion as wave can attack the coast without obstacles.
