10 Curiosities About the Oceans That You Still Do Not Know

We call the large expanses of water on planet Earth oceans, especially those that separate two or more continents. The oceans are classified into three great oceans: Atlantic, Indian and Pacific; and two smaller Arctic and the Antarctic, partially delimited by the shape of the continents and archipelagos. We present you 10 curious facts about the Oceans:

1. The largest surface on the planet
The oceans make up most of the planet’s surface. Water covers more than 361 million square kilometers of the earth’s surface, almost 71 percent of the entire planet.

2. Composition of sodium and chlorine
The water that makes up the oceans is made up of 90% sodium and chlorine, which in their solid form combine to form sodium chloride or common salt, and magnesium, calcium, and potassium.

3. 94% of the water on planet Earth is in the sea
Most of the water on Earth, 94%, is found in the oceans, from which a greater quantity of pure water evaporates than that which returns in the form of precipitation.

4. It houses the largest mountain in the world
Under the waters of the ocean is the largest mountain in the world: the Mauna Kea volcano, in Hawaii, which measures 10,203 meters of which only 4,213 emerge from the sea.

5. Millions of cubic kilometers of liquid
It is estimated that to store all the water on Earth we would need a container with a capacity for 350 million cubic kilometers of liquid.

6. We only know 5% of the ocean
As only 5% of the oceans have been explored, so they are known as the last wilderness. In fact, we have better maps of Mars than of the seafloor.

7. Geography of the ocean is very particular
The oceans have a host of unique geographic features, such as building-size pillars or chimneys that release sulfuric acid to the surface.

8 stop global warming
The oceans are a great ecological filter and one of the great actors to stop global warming. Marine waters are estimated to absorb 2 billion tons of carbon dioxide, one of the main greenhouse gases.

9. It gives us energy
The energy generated by the tides is a source of use. The first commercial attempt was made on the English Channel, in the city of Saint Maló (France). Inaugurated in 1966, the plant is equipped with 24 reversible turbines. The potential energy of the tides in the English Channel reaches 180,000 megawatts.

10. Receive 8 million tons of plastic per year
Every year, eight million tons of plastic reach the oceans. It is estimated that in 2,050 there will be more plastics than fish. Ecologists, inventors, scientists, and politicians are trying to put a stop to this catastrophe.
