You think that you have some imaginations of how deep the ocean is? In our opinion your vision will be changed after watching the video which is explaining and exploring how deep the ocean actually is.
In this video the author explored just how deep the ocean actually is while discussing some of the strange life down there.
An ocean is a body of saline water that composes much of a planet’s hydrosphere. On Earth, an ocean is one of the major conventional divisions of the World Ocean. These are, in descending order by area, the Pacific, Atlantic, Indian, Southern (Antarctic). The word sea is often used interchangeably with “ocean” in American English but, a sea is a body of saline water.
Saline water covers approximately 360,000,000 km2 (140,000,000 sq mi) and is customarily divided into several principal oceans and smaller seas. The ocean contains 97% of Earth’s water, and oceanographers have stated that less than 5% of the World Ocean has been explored. The total volume is approximately 1.35 billion cubic kilometers with an average depth of nearly 3,700 meters.
As the world ocean is the principal component of Earth’s hydrosphere, it is integral to life, forms part of the carbon cycle, and influences climate and weather patterns. The world ocean is the habitat of 230,000 known species, but because much of it is unexplored, the number of species that exist in the ocean is much larger, possibly over two million. The origin of Earth’s oceans is unknown; oceans are thought to have formed in the Hadean eon and may have been the impetus for the emergence of life.
The word « ocean » comes from the figure in classical antiquity. The elder of the Titans in classical Greek mythology is the divine personification of the sea, an enormous river encircling the world.
