Respuesta :
Both are hard structures that reduce erosion causes by waves.
Answer: Option C
Explanation:
Jetties and sea walls are constructed near the beach to reduce erosion caused by waves. Sea wall is a hard wall construction built on the beach to protect the nearby land structures from being affected by waves. It is built very high to protect from wave topping.
Jetty is normally a wooden construction built to berth the ships. It is constructed to artificially increase the beach size which can be used for recreational purposes. Both are constructed using stones, cement and it provides as a protection from coastal flooding.
Both the jetties and seawalls are the hard structures, which diminish erosion resulting due to waves.
The management of beach erosion:
The phenomenon of beach erosion takes place when the supply of sand to the beach fails to match up with the loss of sand to the sea. To curb the issue, the sea walls and jetties are created close to the beach to minimize the erosion resulting due to waves.
The hard wall constructed on the beach to safeguard the adjacent land compositions from getting influenced by the waves is known as a sea wall. On the other hand, a wooden construction developed to berth the ships is known as a jetty. It is developed to enhance the size of the beach artificially that can be used for recreational purposes. Both the constructions provides protection from the coastal flooding.
Thus, the correct statement is that both are hard structures, which reduce erosion resulting due to waves.
