Explain how huma activity has increased the rate of beach & shoreline erosion.?

Question

~*Science Warm-Up!~

Answer 1

Beach and foreshore areas are dynamic zones. That means that they are always changing. The problem is when people build houses on them. Houses don't move, but the beach front does. People see this as a concern and want to stop the erosion that is naturally occurring to stop their investments ending up in the sea.

One way that humans have increased beach erosion is by building break walls. This does not allow the wave energy to dissipate along a wide area like a beach. Instead waves hit the wall with a greater energy and bounce back out to sea only to be met with another wave. The resulting energy moves up and down (big splash) instead of out to sea removing sediments along to bottom and transporting them up current causing erosion.

Answer 2

New Orleans used to have pine barrens that protected us from hurricanes, for one thing. But no, rich people wanted a view from their homes, so they built houses instead...
and the shoreline has decreased, and think of all the extra silt and dirt and cement pebbles that went with all the water they had to pump out...

Answer 3

ok think of approximately it. As interest will advance, which skill you get off your chair and run around, respiratory (velocity which you breathe)will advance (velocity up) or shrink (decelerate) or stay consistent. nicely, i'm going to tell you this... I unquestionably have been sitting right here awhile, so all of the interest it would take for me could be to arise and stroll downstairs to alter the laundry and that i might initiate respiratory heavy! the respond is A. it would advance. i did not choose to in basic terms answer it for you, i wished to describe it, too.
