Answers
Answer:
1. Three Types of movement of ocean water are waves, tides and currents.
2. Waves are caused by the action of winds.
3. Indian ocean Tsunami took place on December 26, 2004.
4. The alternative rise and fall in the level of sea water is called a tide.
5. The continuous movement of ocean water in a definite direction is called ocean current.
Answer:
1) (a) Waves
(b) Tides
(c) Ocean currents
2) Waves
Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest.
3) Sunday, 26 December 2004
Indian Ocean earthquake and tsunami.
4) Tides
Tides are the daily rise and fall of sea level at any given place. The pull of the Moon’s gravity on Earth is the primarily cause of tides and the pull of the Sun’s gravity on Earth is the secondary cause . The Moon has a greater effect because, although it is much smaller than the Sun, it is much closer. The Moon’s pull is about twice that of the Sun’s.
5) Ocean Currents
Ocean water moves in predictable ways along the ocean surface. Surface currents can flow for thousands of kilometers and can reach depths of hundreds of meters. These surface currents do not depend on weather; they remain unchanged even in large storms because they depend on factors that do not change.
