A sea is smaller than an ocean. Seas are located where the land and ocean meet. The sea is a part of the ocean that is partially enclosed by land.
Oceans, seas and sea channels are all saline bodies of water distinguished by their relative sizes, with oceans being the largest, followed by seas and sea channels. Seas and sea channels also are defined by their relationship to land. Oceans, on the other hand, are so large that their relationship
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.
Africa, the world's second-largest continent, is bounded by the Atlantic, Indian and Southern oceans, as well as by the Red and Mediterranean seas. The continent straddles the equator and sits between the landforms of southern Europe and Asia, giving it a complex coastal geography and a wide range o
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
As a system of interconnected bodies of salt water, oceans cover 70 percent of the earth's surface and hold 97 percent of the planet's water supply. The five major oceans of the world are the Pacific Ocean, the Atlantic Ocean, the Indian Ocean, the Southern Ocean and the Arctic Ocean.
Only about 30 percent of the Earth's surface is dry land, oceans make up the remaining 70 percent. Earth's oceans are home to hundreds of thousands of marine life forms, but because most of the ocean depths remain unexplored, hundreds of thousands or even millions of unclassified life forms may exis
The Red Sea is an inlet of the Indian Ocean that separates northeastern Africa from Asia minor. Specifically, the Red Sea borders Saudi Arabia and Yemen on its eastern shore and Egypt, Sudan, Eritrea and Djibouti on its western shore. The Red Sea has one of the highest salt concentrations of any bod
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.
The Strait of Gibraltar links the Mediterranean Sea to the Atlantic Ocean. It takes its name from the Rock of Gibraltar, which comes from the Arabic words "Jebel Tariq," or "Tariq's Mountain." The strait is bordered by Spain, Morocco and Gibraltar, a British colony.
