Oceans lay claim to about 70 percent of the surface of the earth, and ocean life accounts for 94 percent of living things. Despite this, scientists have yet to explore most of the ocean, as its average depth surpasses 12,400 feet and is mostly cloaked in darkness.
There is only one ocean on the planet, but it is divided into five sections or five oceans. The five sections of the ocean are the Atlantic, Pacific, Southern, Arctic and Indian oceans.
The ocean covers 321,003,271 cubic miles, or 70 percent of the Earth's surface, according to the National Oceanic and Atmosphere Administration. A cubic mile is the volume of a cube that measures 1 mile on each side. The ocean makes up 96 percent of the Earth's water.
The ocean is important to life on Earth because of the role it plays in both the hydrologic cycle and the carbon cycle. The hydrologic cycle, also known as the water cycle or H2O cycle, refers to the relationship that exists between the circulation, evaporation and precipitation of water on the plan
Octopuses, jellyfish, sharks, sea stars and sea turtles are a few of the numerous animal species that inhabit the oceans. Since most plants need sunlight to carry out photosynthesis, many underwater plants make their homes close to the shore. Phytoplankton is one of the most common plant types.
Oceans cover the majority of the Earth's surface, which is why the Earth appears blue from outer space. Oceans cover over 129 million square miles of Earth, which is about 65.7 percent of the Earth's surface. The deepest part of the oceans can reach a depth of over 6 miles, and the ocean contains 97
The earth's five oceans are the Indian, Arctic, Southern Antarctic, Atlantic and Pacific. Historically, countries around the world recognized four of the five oceans, excluding the Southern Antarctic Ocean from the count. The International Hydrographic Organization recognizes this ocean, which exten
The ocean is home to many different species of plankton, marine invertebrates, cephalopods, marine mammals and sea turtles. Other creatures that live in the ocean include numerous types of fish, sharks and corals.
Earth's oceans are the Pacific Ocean, the Atlantic Ocean, the Arctic Ocean, the Southern Ocean and the Indian Ocean. The Pacific is Earth's largest ocean at over 60 million square miles.
Nearly 3.8 billion years ago, temperatures on Earth cooled below 100 degrees Celsius for the first time, allowing water, which existed on the planet in gaseous form, to condense into rain and collect on the planet's surface, according to the American Museum of Natural History. This water collected i
