Overview

Ocean water is never static. It moves in three main ways: waves, currents, and tides. Waves are oscillatory movements that make the sea surface rise and fall, while currents are regular movements of water in a definite direction over great distances. Tides are the periodic rise and fall of sea level

Key Concepts

Ocean waves are oscillatory movements

Ocean waves are oscillatory movements in water, shown by an alternate rise and fall of the sea surface. Only the wave travels forward, while water par

The upper part of a wave

The upper part of a wave is called the crest and the lower part is called the trough. The distance between two consecutive crests or troughs is the wa

Velocity of wave (C) = Wavelength

Velocity of wave (C) = Wavelength (L) / Period (T). This formula connects the size of the wave with the time taken for its movement.

Sea is an irregular wave pattern

Sea is an irregular wave pattern formed by waves of different wavelengths moving in different directions. Swell is a more uniform pattern formed when

Ocean currents are regular movements

Ocean currents are regular movements of a mass of water in a fairly defined direction over great distances. Unlike waves, the water in currents moves
