Movements of Ocean Water

In the NCERT Geography book Fundamentals of Physical Geography (Class 11, Chapter — “Movements of Ocean Water”), you explore the different types of movements that occur in ocean waters and how they influence the Earth's climate and coastal environments.

You learn about three major movements of ocean water — waves, tides, and ocean currents. Waves are generated mainly by the wind blowing across the ocean surface, while tides are caused by the gravitational pull of the Moon and the Sun.

The chapter also explains ocean currents, which are large streams of moving ocean water. You study warm currents and cold currents, and how they affect climate, weather patterns, and marine ecosystems around the world.
