The Ocean is Much Deeper Than You Think, and This Video Shows It

According to recent estimates by oceanographers, less than 5% of the World Ocean has been explored.

Did you know that the oceans cover up to 70% of the Earth’s surface and 90% of the Earth’s biosphere? Our planet’s oceans are so vast, they contain roughly 97% of the Earth’s water supply.

And our planet’s oceans are the reason why our planet is so unique. There are no oceans like those on Earth anywhere else in our solar system.

In fact, there isn’t a planet in our Solar System that has liquid water on its surface (however, it is noteworthy to mention that recent discoveries on Mars indicate that the red planet may have great amounts of surface liquid in the recent past).

It is firmly believed that life on Earth arose from the ocean, and while countless species have developed and move away from the ocean, our planet’s oceans continue to be home to countless lifeforms, some of which are still waiting to be discovered.

The ocean is divided into three zones based on depth and light level. Although some sea creatures depend on light to live, others can do without it. Image Credit: NOAA.

The largest ocean on our planet is the Pacific Ocean, covering up to 30% of the Earth’s surface. The second largest ocean on our planet is the Atlantic Ocean, it covers up to 21% of the Earth’s surface. The third largest ocean on our planet is the Indian Ocean which covers up to 14% of the Earth’s surface.

And with that much water existing on Earth, you have got to ask why is our planet even called Earth? It should have been named water, don’t you think?

Anyway, the total volume of the ocean is believed to be at around approximately 1.35 billion cubic kilometers (320 million cu mi) with an average depth of nearly 3,700 meters (12,100 ft).

Earth’s oceans also have a number of functions, and their existence greatly affects the weather and temperature on the surface of the planet.

The Oceans on Earth moderate our planet’s temperature by absorbing incoming solar radiation (stored as heat energy).

Continuously moving ocean currents distribute heat energy around the globe. This process is what heats the land and air on Earth during winter, and cools it during summer, helping our planet remain stable for life to exist.
