A sea is a large body of salty water. There are particular seas and the sea. The sea commonly refers to the ocean, the wider body of seawater . Particular seas are either marginal seas, second-order sections of the oceanic sea (e.g. the Mediterranean Sea ), or certain large, nearly landlocked bodies of water. The salinity of water bodies varies ...
Nowadays, we of course know that there are more than seven seas on our blue planet. Let’s see a list of major seas of the world with a small description for each of them! Philippine Sea – 5.695 million km2. Coral Sea- 4.791 million km2. American Mediterranean Sea – 4.200 million km2. Arabian Sea – 3.862 million km2.
Because sea ice is less dense than water, it floats on the ocean's surface (as does fresh water ice, which has an even lower density). Sea ice covers about 7% of the Earth's surface and about 12% of the world's oceans. Sea ice usually starts to freeze at the very surface, initially as a very thin ice film. As further freezing takes place, this ice film thickens and can form ice sheets. The ice formed ...
Jun 14, 2024 · Ocean, continuous body of salt water held in enormous basins on Earth’s surface. There is one ‘world ocean,’ but researchers often separate it into the Pacific, Atlantic, Indian, Southern, and Arctic oceans. Covering nearly 71 percent of Earth’s surface, the oceans have an average depth of 3,688 metres (12,100 feet).
Oct 19, 2023 · A sea can be more than 2.6 million square kilometers (1 million square miles) in area, such as the Caribbean Sea. Or, it can be as tiny as the Sea of Marmara, which is less than 12,950 square kilometers (5,000 square miles) in area. This tiny Turkish sea connects the Aegean Sea and the Black Sea. A sea can also be very warm for most of the year. The Red Sea, for instance, has an average temperature of around 30 degrees Celsius (86 degrees Fahrenheit).

Jul 11, 2024 · Seawater, water that makes up the oceans and seas, covering more than 70 percent of Earth’s surface. Seawater is a complex mixture of 96.5 percent water, 2.5 percent salts, and smaller amounts of other substances, including dissolved inorganic and organic materials, particulates, and a few atmospheric gases.
Mar 5, 2024 · Sea animals are harmed by the plastic either by getting tangled in it or by eating it. An example of marine pollution consisting mainly of plastics is the Great Pacific Garbage Patch. The Great Pacific Garbage Patch is a floating dump in the North Pacific. It’s about twice the size of Texas and probably contains about 100 million tons of debris. Most of this debris comes from the western coast of North America (the U.S. and Canada) and the eastern coast of Asia (Japan, China, Russia, North ...
Jun 25, 2024 · The ocean is a huge body of saltwater that covers about 71 percent of Earth’s surface. The planet has one global ocean, though oceanographers and the countries of the world have traditionally divided it into five distinct regions: the Pacific, Atlantic, Indian, and Arctic oceans. Beginning in the 20th century, some oceanographers labeled the seas around Antarctica the Southern Ocean, and in 2021 National Geographic officially recognized this fifth ocean.
Sea animals like zooplankton are so small you can see them only with a microscope. Big fish swim through these waters too, such as great white sharks, manta rays, and ocean sunfish. The largest animal ever to live on Earth is an ocean mammal called the blue whale. It’s as long as two school buses! Dolphins, porpoises, and sea lions are also ocean-dwelling mammals.
