An
ocean is an enormous body of salt water. The oceans are spread on more
than 70 % of Earth's surface. The water is contained in the oceans is
about 98 percent of all the water on Earth. Only 2 percent of water
is found in well pond rivers etc.
There
are five oceans in the world.
1.The
Pacific,
2.The
Atlantic,
3.The
Indian,
4.The
Arctic, and
5.The
Southern, or Antarctic.
When
you see the map of the world, you would not find any genuine
boundary to limit the oceans because there is only one vast ocean. We
(human beings) have divided it into five for our convenience. We have
named the different regions of the ocean by various names.
In
addition to the fact that the oceans provide a home for a large number of
plants and creatures, however, they likewise help in regulating the
world's climate and temperature. The oceans keep the earth hotter in
the winter and cooler in the late spring.
The
5 Oceans by Size

Indian
(70,560,000 sq km)
Southern
(21,960,000 sq km)
Arctic

In places, the Pacific ocean is very deep. At Marina Trench, it is found
35,827 ft deep. Which is incredible.
Ocean
life
The
ocean is the house of about one million species of animals. Most of
them are invertebrates. They are without the backbone. Some of the
ocean animals are so small that cannot be seen with naked eyes. They
are the microscopic sea animals. Small fishes like bristlemouth and
big fishes like white sharks are also found in the sea. The oceans
are really big. From the smallest animals like zooplankton to the
biggest animal-like blue whales are found in the oceans.
The
sea overflows with vegetation. Most are little green growth called
phytoplankton. They produce most of the oxygen for marine animals.
Big algae for instance seaweed provide food and shelter for sea
animals.
Why
should we care about the ocean?
The
ocean produces over half of the world's oxygen and absorbs carbon
dioxide largely.
It
is one of the cheapest and very effective ways of transportation.
Oceans
help in regulating the world's climate and temperature.
We
get a lot of seafood from the ocean.
The
medicine of cancer, arthritis, Alzheimer's disease is prepared from
sea plants and animals.
