makes the Earth blue…
When you look at a globe, 70% of our planet
is covered with oceans. Humans are the most intelligent form of life on Earth,
but we can only live in 30% of it! The ocean is a mystery to us; there is still
so much about it that we need to discover. In fact, we know more about outer
space than what’s going on underneath the deep blue seas.
The ocean is where life started. There are
so many species that we are only starting to discover. At first, we thought
that there can be no life deep beneath the sea, since sunlight cannot reach it.
We were wrong. There are all kinds of life beneath the ocean! Life that doesn’t
require sunlight like we do. Fish and animals that live in environments where
we can’t go.
Facts about Earth
It’s wonderful to know that Life can exist
in different environments! Thousands of miles below the sea, it’s a different
world. It’s as alien to us as another planet… and yet, what happens to our
oceans affect those of us who live on land.

- There are 4 major Oceans: The
largest ocean on Earth is the Pacific Ocean. It covers 30% of the planet’s

other oceans combined. The Atlantic Ocean is the 2nd largest,
covering 21% of the Earth’s surface. The 3rd largest ocean is the
Indian Ocean. It covers around 14% of the planet and it is the warmest. The

Facts about the Ocean
- The fish living 3000 meters
below the ocean have their own lights! Well, it is very dark down there.
- The Dead Sea in the Indian
Ocean is the saltiest. It’s so salty that nothing can live in its waters. The
large amounts of salt exert an upward push and you will float in the water
without any effort.
- Coral Reefs are made by billions of small sea
animals. When they die, they leave their skeletons behind and this forms the
coral reefs very very slowly.
are Coral Reefs in Danger?
- 25% of marine animals live in
the coral reefs… and 90% of sea life relies on the reefs for one reason or
- The largest coral reef is
located in Australia –The Great Barrier Reef.
- The deepest on Earth can be
found in the Pacific Ocean. It’s called the Mariana Trench. It is around 10,900
- The ocean is responsible for
the weather. The currents distribute heat around the planet and temperature
above the oceans creates clouds and winds.
- The ocean tides rise and fall
twice a day. It is caused by the gravitational pull of the Moon.
are our Oceans today?
Our beautiful life giving ocean has a lot
of problems today… We are polluting it, global warming is causing the sea
levels to rise and the ocean is getting warmer. Some marine animals are in
danger of going extinct, such as the blue fin tuna and the whales.
