The deepest known spot in the ocean is the Mariana Trench, southwest of Guam, it is 36, 198 feet below
the surface (11,033 meters).

It covers 63, 800,000 square miles (165, 200, 000 square kilometers).
The Pacific Ocean is so big it could fit all of the Earth’s continents.

The Atlantic Ocean covers about 31, 530,00 square miles (81, 662, 000 square kilometers).
Its average depth is about 14,000 feet (4,270 meters).
The deepest part of the Atlantic Ocean is the Puerto Rico Trench 28, 374 feet (8,648 meters).
is smaller than the Atlantic.
The Indian Ocean covers about 28,356,000
square miles (73,441,700 square

The deepest spot is 25,344 feet (7,725

If the ocean's total salt content were dried, it would cover the continents to a
depth of 5 feet.
The Antarctic Ice Sheet is almost twice the size of the United States.

RANDOM FACTS• The sea level has risen with an average of 10-25 cm over the
past 100 years and scientists expect this rate to increase.10,000 years ago the ocean level was about 110 m lower than it is now. If all the world's ice melted, the oceans
would rise 66 m.• Antarctica has as much ice as the Atlantic Ocean has water.• Each year, three times as much garbage is dumped into the
world's oceans as the weight of fish caught.• The record for the deepest free dive is held by Jacques Mayol.
He dove to an astounding depth of 86 m without any breathing equipment
• A mouthful of seawater may contain millions of bacterial cells, hundreds of thousands of phytoplankton and tens of
thousands of zooplankton ..• The swordfish and marlin are the fastest fish in the ocean
reaching speeds up to 121 kph in quick bursts; the bluefin may reach sustained speeds up to 90 kph.
• The oceans cover 71% of the Earth's surface and contain 97% of the Earth's water. Less than 1% is fresh water, and
2-3% is contained in glaciers and ice caps.
• 90% of all volcanic activity occurs in the oceans.
• The speed of sound in water is 1,435 m/sec - nearly five times faster than
the speed of sound in air.• The top ten feet of the ocean hold as
much heat as the entire atmosphere.• Life began in the seas 3.1 billion to 3.4
billion years ago. Land dwellers appeared 400 million years ago
