The Arctic Ocean is the coldest ocean and has average temperatures of about 28 degrees Fahrenheit. The ocean measures 5.4 million square miles making it the smallest of the world's oceans.
The Challenger Deep in the Mariana Trench is the deepest known point in Earth's oceans. In 2010 the United States Center for Coastal & Ocean Mapping measured the depth of the Challenger Deep at 10,994 meters (36,070 feet) below sea level with an estimated vertical accuracy of ± 40 meters.
The deepest point ever reached by man is 35,858 feet below the surface of the ocean, which happens to be as deep as water gets on earth. To go deeper, you'll have to travel to the bottom of the Challenger Deep, a section of the Mariana Trench under the Pacific Ocean 200 miles southwest of Guam.
Definition of Shallow area. Shallow area means portions of a pool or spa with water depths five feet or less.
Invertebrates like sponges, molluscs, sea fans, worms, crabs, and echinoderms are common too. While different species are found in different areas of the shallow ocean, the general types of animals, algae, and plants that you will find in different places can be similar.
However, in terms of average depth, the Pacific Ocean is the deepest. Though calculations vary, it is estimated that the entire ocean floor averages about 4,280 meters (14,042 ft), which is over 500 m (1640 ft) deeper than the global average of 3,700 meters (12,100 ft).

As of 2016, the warmest ocean in the world is the Indian Ocean.
O. megalodon was not only the biggest shark in the world, but one of the largest fish ever to exist. Estimates suggest it grew to between 15 and 18 meters in length, three times longer than the largest recorded great white shark.
It has therefor been close to 500 years that it has been known that there is essentially no end to the ocean, just as there is no obvious end to a line drawn on the surface of a smooth ball. You can also learn the answer to your question by looking at, and examining, an ordinary globe of the Earth.
The Atlantic Ocean ranks the second in the catalogue of the most dangerous ocean waters in the world. This ocean water is usually affected by coastal winds, temperature of the water surface and the water currents. Sometimes the Atlantic is dangerous, sometimes the Pacific more so.
Continents & Oceans Lesson - Elementary Social Studies - My Schoolhouse - Online Learning. The seven continents are North America, South America, Europe, Asia, Africa, Australia, and Antarctica. The five oceans are the Pacific Ocean, the Atlantic Ocean, the Indian Ocean, the Arctic Ocean and the Southern Ocean.
While the South Pole lies on a continental land mass, the North Pole is located in the middle of the Arctic Ocean amid waters that are almost permanently covered with constantly shifting sea ice.
The temperature of the surface of the Arctic Ocean is fairly constant, near the freezing point of seawater. Because the Arctic Ocean consists of saltwater, the temperature must reach −1.8 °C (28.8 °F) before freezing occurs. Much of the Arctic ice pack is also covered in snow for about 10 months of the year.
Salt in the ocean comes from rocks on land. The rain that falls on the land contains some dissolved carbon dioxide from the surrounding air. Together, they make up over 90 percent of all dissolved ions in the ocean. Sodium and Chloride are 'salty.
The name arctic originates from the word 'arktos' which is a Greek word that means bear. The name originates from ursa major and ursa minor constellations that represent the great and little bear respectively. They are seen in the northern hemisphere where they point the north star, hence the name Arctic.
First off, here are the average depths of the earth's oceans; the Arctic Ocean is 1,038 meters (3,407 feet) deep, the Indian Ocean is 3,960 meters (12,990 feet) deep, the Atlantic Ocean is 3,339 meters (10,955 feet) deep and the Pacific Ocean is 4,188 meters (13,740 feet) deep.
Arctic Sea ice melts in the summer, and more of the sun is being absorbed by the ocean. The fast rate of the sea ice melting is resulting in the oceans absorbing and heating up the Arctic. The decline in sea ice does have a notable potential to significantly speed up global warming and the climate changes.
A recent census estimates there to be about 240 fish species in the Arctic, mostly sculpins, snailfishes, eelpouts, and cods. Probably one of the most numerous fish species in the Arctic is the Arctic cod, which takes a central role in linking the sea ice-associated and water column food webs to higher level consumers.
Arctic icebergs. Most Arctic icebergs originate from the fast-flowing glaciers that descend from the Greenland Ice Sheet. Many glaciers are funneled through gaps in the chain of coastal mountains. The Arctic Ocean's equivalent of the classic tabular iceberg of Antarctic waters is the ice island.
Average January temperatures range from about −34 °C to 0 °C (−29 to +32 °F), and winter temperatures can drop below −50 °C (−58 °F) over large parts of the Arctic. Average July temperatures range from about −10 to +10 °C (14 to 50 °F), with some land areas occasionally exceeding 30 °C (86 °F) in summer.
The North Pole sits in the middle of the Arctic Ocean, on water that is almost always covered with ice. The ice is about 2-3 meters (6-10 feet) thick. The depth of the ocean at the North Pole is more than 4,000 meters (13,123 feet).
The Arctic (/ˈ?ːrkt?k/ or /ˈ?ːrt?k/) is a polar region located at the northernmost part of Earth. The Arctic consists of the Arctic Ocean, adjacent seas, and parts of Alaska (United States), Finland, Greenland (Denmark), Iceland, Northern Canada, Norway, Russia and Sweden.
So the Arctic Ocean has a layer of cold, fresh water near the surface with warmer, saltier water below. This cold, fresh water layer typically allows more ice growth in the Arctic than the Antarctic.
The Arctic Ocean is the coldest ocean and has average temperatures of about 28 degrees Fahrenheit. The ocean measures 5.4 million square miles making it the smallest of the world's oceans.
Although the Arctic Ocean is by far the smallest of the Earth's oceans, having only a little more than one-sixth the area of the next largest, the Indian Ocean, its area of 5,440,000 square miles (14,090,000 square km) is five times larger than that of the largest sea, the Mediterranean.
Both the Arctic (North Pole) and the Antarctic (South Pole) are cold because they don't get any direct sunlight. The Sun is always low on the horizon, even in the middle of summer. In winter, the Sun is so far below the horizon that it doesn't come up at all for months at a time. The Arctic is ocean surrounded by land.
