The ocean is home to nearly 95% of life: The ocean covers 70% of the Earth’s surface and about 95% of the life on Earth exists here.
The longest mountain range in the world lies under the sea: The longest mountain range on the planet Mid-Ocean Ridge is almost entirely under the sea, stretching 65,000 km, 10 times longer than the Andes.
Oceans also have rivers and lakes: These rivers and lakes are formed when seawater seeps through thick layers of salt on the seafloor, causing them to collapse and form subsidence zones. The dissolved salts cause the water to be denser than the water above it and thus settle to form rivers and lakes. They even have riverbanks, mudflats and waves.
We have discovered less than 5% of the planet’s oceans. That’s why the map of Mars is more detailed than the map of the oceans on Earth.
More than 90% of life forms on the planet have not been discovered: Very few oceans have been discovered and most organisms live in the water. It is estimated that 91% of marine species are undiscovered.
There are about 3 million wrecks in the ocean. So there are even more artifacts under the ocean than all the museums in the world put together.
More than 70% of the oxygen on the planet is produced by the oceans.
Most of our planet is in darkness: Since the oceans have an average depth of nearly 3,700 meters, but light waves only penetrate 91 meters of water, everything below this depth is dark.
Most of the volcanic activity on Earth takes place in the oceans. The place with the most volcanoes on Earth is in the Pacific Ocean with 1,133 volcanoes.
Tsunamis can travel over the oceans at a speed of 805km/h when the ocean depth is 6km. When they are in the deep sea, they are usually only a few centimeters above sea level, but as they approach land and shallow water, they can be much taller and move more slowly.
The Pacific Ocean is wider than the Moon: At its widest point, from Indonesia to Colombia, the Pacific Ocean is actually much wider than the Moon. This distance of the ocean is 19,794 km, more than 5 times the diameter of the Moon.
Earth’s largest waterfall is located under the sea: The highest waterfall on land is Angel Falls in Venezuela when it falls nearly 1,000 meters but it is still nothing compared to the Denmark Strait Cataract – an underwater waterfall located between Greenland and Iceland when it fell more than 3,500 meters.
Undersea pressure can crush us in an instant: At the Mariana Trench, which is nearly 11,000 meters deep, we will find the deepest point on the planet with enough water pressure to crush us in an instant.
More people have set foot on the Moon than in the Mariana Trench: Dozens of people have set foot on the Moon, but only 3 people have reached the Mariana Trench because of the harsh conditions here.
The water on the ocean floor is extremely hot: While in many of the deepest places in the ocean, the temperature is only about 2-4 degrees Celsius, the water in the hydrothermal vents on the seafloor, the temperature can be up to 400 degrees Celsius. What’s keeping the water from boiling here is thought to be the overwhelming pressure at these deep points.
Sharks have their own “cafe” under the sea: In 2002, scientists discovered a remote area in the Pacific Ocean between Baja California and Hawaii, where sharks come here to chat. then back to his own sea.
