Question
Differentiate between the three movements of ocean water-waves, tides, and currents.
Solution
Waves are oscillatory movement in the water, manifested by an alternate rise and fall of the sea surface. Every wave has a wavelength, velocity, height, and wave period. The rise and fall of seawater due to gravitational forces of the sun and the moon are called tides. The sea waves produced by tides are called tidal waves. Ocean currents are large masses of surface water that circulate in regular patterns around the ocean. It is of two types warm and cold.
