The world's oceans cover almost three-quarters of the Earth's surface. Over 97 percent of the Earth's water is salt water. The oceans may seem mysterious and inaccessible, but scientists explore the oceanic zone using numerous tools. As the oceans' secrets are discovered, scientists describe ...
The Ocean Twilight Zone Project is a group of scientists trying to understand this oceanic zone’s secrets. The twilight zone showcases nature’s ingenuity. Since there is so little light, many creatures create their own light to attract food, like inFinding Nemo. While others use bioluminescenc...
Viperfish are fierce predators Viperfish are one of the fiercest predators living in the deep ocean that attract their prey with a “fishing lure”Four major oceanic zones Oceanographers divide the oceans into oceanic zones. Most plant and animal life live in one specific zone....
The average depth of the oceans is about 3,500 m/ 11,482 ft. However, the depth of the oceans varies widely depending on the location on the tectonic plates. Ocean trenches are deep depressions on the ocean floor that are found in all ocean basins and the places where tectonic plates me...
Down in the South Pacific Ocean, far below the equator, there's a place called Point Nemo, also known as the "Oceanic Pole of Inaccessibility." At this location, you're literally as far away from dry land as a person can get anywhere on the planet. You'd have to travel more than ...
This feature, though of tremendous proportions, is but the Atlantic portion of the world-encircling oceanic ridge. Elements of the continental margin(more) In some places the Mid-Atlantic Ridge reaches above sea level to form islands. Iceland, which rises from its crest, is rent by an ...
As the rift widened with time, it led to the expansion or the spreading of the sea floor. Magma welled up along this rift and formed a new oceanic crust, ultimately forming the Red Sea. The Gulf of Suez is an extension of the Red Sea and gradually took shape due to rifting and seafl...
The shape of the oceans and seas of the world has changed significantly throughout the past 600 million years. According to the theory of plate tectonics, the crust of the Earth is made up of many dynamic plates. There are two types of plates—oceanic and continental—which float on the ...
Phytoplankton, seagrass, and kelp that grow here make up the basis of most oceanic food webs. The next zone down is the Twilight Zone, from around 700 feet to 3280 feet (200 to 700 meters). This area receives a lot less sunlight and supports a smaller variety of fish and no plants. ...
