Go to Slide 23. Jetties can be installed to prevent sand erosion. Where is the location where these jetties have been installed? Country/Province/State: In which direction is the current moving the sand? How can you tell? (Use the images and the description in Slide 22 to help you answer this question).

Hello. You did not present the images to which this question refers, which makes it impossible for it to be answered, but I will try to help you in the best possible way.

Jetties are usually installed on the shoreline of water bodies, allowing for a barrier that blocks the flow of water capable of causing erosion, which occurs when water drags sand from the beach along the coast.
