Type of Erosion Control<span> </span>Pros of Using this Control
- Jetties - protect buildings on beaches from losing sand
- Breakwaters - Stop the waves from hitting the beach
- Beach Renourishment - easy way to prevent sand erosion
- Planting of dune grasses and plants - roots hold sand together and make it more difficult to wash away
Cons of Using this Control
- can seriously affect the tidal circulation and the health of wetlands
- changes profile of the beach
- can cause bottom organisms and habitats to e smothered by muddy water
- can make the beaches difficult to use for recreation
<span>Paragraph:
</span> I think that Breakwaters<span> are the best to use. One reason is the only major con that is has is changing the profile of the beach instead of harming wildlife and taking away funding (recreational use.) Another reason is that the rocks used provide great climbing tools for beachgoers and might entertain them. A third reason is that breakwaters can be underground as well, not damaging the beach very much. Finally, they save millions of dollars in replacing sand.</span>
In the mid-twentieth century and corroborated ever since, researchers dredging the seafloor could not find any materials older than 180 million years.

What do you understand by seafloor ?</h3>
The surface of an ocean or sea: seafloor According to this theory, the Earth's crust is divided into a number of enormous plates that together form the continents and ocean floors and are supported by a warm, plastic "mantle" beneath the surface. Mr. Walter Sullivan
Deposits of common minerals like copper, zinc, nickel, gold, silver, and phosphorus can be found on the seafloor. These deposits are nodules on silt from the abyssal plain that are typically 3 to 10 centimeters (1 to 4 inches) in diameter and appear as crusts on volcanic and other rocks.
