The Mariana trench is the deepest trench in the WORLD
The Seafloor :)

Barrier Islands can be ''re-shaped'' by hurricanes because of the damaging winds and heavy rain fall
Brown and green are the colors of the Estuary. It's here that rivers meet the sea in shallow, protected bays
Long-shore currents can sweep swimmers and surfers into rip currents, piers, jetties, and other hazardous areas. In many cases, the long-shore current is strong enough to prevent swimmers from being able to keep their feet on the bottom, making it difficult to return to shore.
The turbid water then rushes downward like an avalanche, picking up sediment and increasing in speed as it flows. Sometimes eroding features (example: Monterrey Bay)
There is a mountain range that extends 10,000 miles along the Atlantic Ocean. It is called the Mid-Atlantic Range and it goes all over the world. (Its like the seems of a baseball)
People who swim at the beach sometimes get sick because the water is polluted. In addition, beaches that aren’t well protected or are overused can be altered or destroyed.
Continental margins constitute about 28% of the oceanic area.
New estimates suggest that, taken together, seamounts encompass about 28.8 million square kilometers of the Earth's surface. That's larger than deserts, tundra, or any other single land-based global habitat on the planet.
Lying generally between the foot of a continental rise and a mid-ocean ridge, abyssal plains cover more than 50% of the Earth’s surface.
The world’s combined continental slope has a total length of approximately 300,000 km (200,000 miles) and descends at an average angle in excess of 4 from the shelf break at the edge of the continental shelf to the beginning of the ocean basins at depths of 100 to 3,200 metres (330 to 10,500 feet).
1. The origin of longshore bars is related to the convergence
of the undertow and the landward flux of material
associated with Stokes drift. Komar calls this the breakpoint hypothesis.
2. Progressive edge waves push sediment out of their path
and form a ‘wall’ at the location of their maximum
3. Longshore bars are a result of reflected wave energy,
forming standing waves and causing the formation of
newer, offshore bars.
The waves at Jaws actually peak near the 30 ft depth contour line near the middle of the ridge.
The width of the shelf varies from place to place; off the coast of southern California in the United States, for example, the shelf is less than 1km wide, whereas off South America, between Argentina and the Falkland Islands, it is more than 500km wide.
This feature can be found all around the world, and it represents the final stage in the boundary between continents and the deepest part of the ocean.
