The document discusses various topics related to oceans including waves, tsunamis, sea creatures in the Indian Ocean, and oceanography. It provides details on how winds cause ocean waves and how tsunamis are typically caused by underwater earthquakes. It also describes some common sea life found in the Indian Ocean like whales, turtles, sailfish, and bottle nose dolphins. The document notes that oceanography is the interdisciplinary study of oceans and seas and explains why it is an important field of research.

3. About the world ocean
 The oceans that make up three-
quarters of the Earth's surface are
realms of boundless energy.

4.  Oceans have been a source of food,
the birthplace of weather systems
that effect the continents, pathways
for commerce, and fields of battle.

5. The winds cause waves on the
surface of the ocean (and on lakes).
The wind transfers some of its
energy to the water, through friction
between the air molecules and the
water molecules.
 Stronger winds (like storm surges)
cause larger waves.

6.  You can make your own miniature waves
by blowing across the surface of a pan of
water.
 Waves of water do not move horizontally,
they only move up and down (a wave does
not represent a flow of water).
 You can see a demonstration of this by
watching a floating buoy bob up and down
with a wave; it does not, however, move
horizontally with the wave.

7. TSUNAMIES

8.  A tsunami (pronounced sue-nahm-ee) is a
series of huge waves that can cause great
devastation and loss of life when they strike a
coast.
 Tsunamis are caused by an underwater
earthquake, a volcanic eruption, an sub-
marine rockslide, or, more rarely, by
an asteroid or meteoroid crashing into in the
water from space.

9.  Mosta tsunamis are caused by underwater
earthquakes, but not all underwater
earthquakes cause tsunamis - an
earthquake has to be over about
magnitude 6.75 on the Richter scale for it
to cause a tsunami.
 About 90 percent of all tsunamis occur in
the Pacific Ocean.

10. It is more than 28 million
square miles in size and covers
almost one fifth of the world’s
surface

12.  The National Oceanic and Atmospheric
Administration (NOAA)

13.  Fact check for Andrew Gliks on –
Ocean heat has paused too | Watts
1199 x 972

14.  The ocean is home to creatures that survive in
saltwater
 And there are a lot kind of water plants also

15. From the large
BALEENWHALE to
the small GREENTARTLE ,
the Indian ocean has a plethora of sea life.

16. Which is the FASTEST Animal
in the ocean ?
 The SAILFISH (BAYONET FISH)is the
FASTEST animal in the ocean.
 The sailfish has been clocked at over 68 miles
per hour over short bursts of speed , because
of its long bill .
 It is common in warm waters in medium
depths but can dive deeply in pursuit of prey.

17. Bottle nose DOLPHIN
 The bottle nose DOLPHIN in habits the
warm tropical oceans , in particular the
north region of Indian ocean
 It can grow up to 14feet & weigh as
much 1100lbs.

18. Studies about OCEAN
 It is called
 Oceanography is the study of
the deep sea and shallow coastal
oceans: biology, chemistry,
geology and physics together
make oceanography a richly
interdisciplinary science

19. Why is Oceanography
important?
 Perhaps the most important
observation is that
oceanography gives you a world
view, ...an understanding of the
global system that is our
environment, which can inspire
your work, wherever it leads.

20.  Humans first acquired knowledge of the
waves and currents of the seas and oceans in
pre-historic times.
 Observations on tides were recorded
by Aristotle and Strabo.
 Early modern exploration of the oceans was
primarily for cartography and mainly limited
to its surfaces and of the creatures that
fishermen brought up in nets, though depth
soundings by lead line were taken.
