"The intertidal zone is the area where the ocean meets the beach, and the neritic zone is the area of the ocean that extends up to a depth of 200 m. This area receives a lot of sunlight. Consequently, is an area rich in life and nutrients."

The intertidal zone is the area that is exposed to the air at low tide and underwater at high tide. It is the area of the beach where the water pulls farther away at low tide exposing the tide pools, rocks and small creatures. At high tide, the water covers this area again until the next low tide. This intertidal zone can vary in depth from less than a foot to several feet deep, depending upon the local topography. The area of the intertidal zone can be a narrow strip, as found in Pacific islands that have only a narrow tidal range, or can include many meters of shoreline where shallow beach slope interacts with high tidal excursion. The movement of the water is callled tidal action. Tides are the rise and fall of sea levels caused by the combined effects of the rotation of the Earth and the gravitational forces exerted by the Moon and the Sun. Most coastal areas experience two daily high and two low tides. This is because at the point right "under" the Moon or what is called the sub-lunar point, the water is at its closest to the Moon, so it experiences stronger gravity and rises. On the opposite side of the Earth or what is called the antipodal point, the water is at its farthest from the moon, so it is pulled less, and at this point the Earth moves more toward the Moon than the water does—causing that water to "rise" relative to the Earth.

The depth of the intertidal zone (the differece in height between low and high tide) varies enormously depending on what part of the globe you live on, the local geography and even the time of year. The average for most of the world is about 1 meter (roughly, 3 feet). However, the tidal reach in the Bay of Fundy is around 16 meters (52 feet).
