2. INTRODUCTON
� Water is the unique part of Earth It includes 71%
of water and 29% of land. Because of this reason
our earth is also known as blue planet.
� We may think that from where do water
originate water originates from mountains .so
water source Is mountain and it will be mixed
with the rivers ,seas and oceans.which is known
as mouth of the river.
� Do you know the watery part of the earth is
known as Hydrosphere which includes ice sheets
from polar regions and the high mountain region
underground Water,Atmosphere and water
vapour.
3. WATER CYCLE
� Water cycle also referred as hydrological cycle is
simplified as the change of water from one form
to another.
� In water cycle water continously moves from the
surface of the earth Into the atmosphere and
reverses again in different forms this is the
formation of water cycle.
� They are overall 4 operations they are
evaporation in the form of water vapour,
condensation which is formed when the
temparature falls in and the precipitation in the
form of rain,snow,heel or sleet and the collection
which collects the water droplets.

submerged mountain is in the middle of this
range which is also known as mid range
mountain.
� They are many ports and harbours along its
coasts it is the busiest ocean in the world in
terms of transpotation the Atlantic ocean Is also
saltiest ocean and its saltinity is contributed by
the process of evaporation,precipitation and
melting and river in flow.
� This river is shaped in the letter ‘s’
9. INDIAN OCEAN
� Indian Ocean � Indian ocean is the 3
rd largest ocean in the
world its name is
given after its country
name this river Is

it remains frozen in the winters.
� This ocean encompasses an area of approximetly
35 million square kilometre
� The southernmost part in the southern ocean is

research base.
13. ARCTIC OCEAN

the south up
� Most parts are remained covered with a thick
sheet through out the year
� The arctic ocean is surrounded by 3 continents

greenland and scandivania and is connected to
the pacific ocean through the narrow bering
strait.

15. IMPORTANCE OF OCEANS
� Oceans are important because they give us
maintain temperature,food,oil and gas and water
etc…
� Ocean help to moderate the earth’s temperature
by absorbing the incoming solar radiation.
� Oceans provide us source of food it has been
estimated that as much as 10 percent of human
protein intake comes from the oceans
� Do you know water takes 1000 years to travel all
the way around the globe.
