California sea lions can be found in the waters of the cove and hauling out, temporarily leaving the water to rest on its beaches, cliffs, and ...
Tidal range is the difference in height between high tide and low tide. Tides are the rise and fall of sea levels caused by gravitational forces exerted by the Moon and Sun, by Earth's rotation and by centrifugal force caused by Earth's progression around the Earth-Moon barycenter.

It is a strong tidal flow of water within estuaries and other enclosed tidal areas. The riptides become the strongest where ...
