Question

Sand at the bottom of a ship channel is dredged and removed to a nearby island's beach. Without this removal process, which of the following would happen?

A) The beaches would narrow and the channel would become shallower.

B) The island would sink as the channel becomes deeper.

C)The island will move inland as the channel becomes deeper

Answer 1

Answer:

[a.] The beaches would narrow as channels become shallower.

Explanation:

According to NOAA, sedimentation can naturally deposit silt by washing it downstream. Dredging helps remove these excess sediments by helping the channels keep their shape. This also helps islands maintain a shoreline.
