Question
In order to preserve their beaches, landowners located along a coast will often build groins that protrude into the sea. What is the result of this process?
1.Sediment is deposited on the side of the groin facing into the current, resulting in deposition in the desired location.
2.More sediment is made available to areas downshore, so they also benefit from this engineering process.
3.Less sediment is available to areas downshore, so their beaches begin to erode.
4.both 1 and 2
5.both 1 and 3 Reset Selection
Explanation / Answer
Answer: Both 1 and 3
Reason: In order to preserve their beaches, landowners located along a coast will build groins that protrude into the sea. During this process less amount of sediments are available at areas of down shore and sediments are deposited on the side of the groin facing into the current, resulting in deposition in the desired location.
