Ovidiu Iordachi Oceans are large bodies of salt water that surround Earth's continents and occupy the basins between them. The four major oceans of the world are the Atlantic, Arctic, Indian, and Pacific. These interconnected oceans are further divided into smaller regions of water called seas, gulfs, and bays.
The combined oceans cover almost 71 percent of Earth's surface, or about , square miles , square kilometers. The average depth is 12, feet 3, meters. Waves erode the land upon which they land as well as the ocean floor.

During the first one to two billion years after Earth's formation, these elemental gases rose through thousands of miles of molten and melting rock to erupt on the surface through volcanoes and fissures long narrow cracks. Within the planet and above the surface, oxygen combined with hydrogen to form water.
Enormous quantities of water shrouded the globe as an incredibly dense atmosphere of water vapor. Near the top of the atmosphere, where heat could be lost to outer space, water vapor condensed to liquid and fell back into the water vapor layer below, cooling the layer.
This atmospheric cooling process continued until the first raindrops fell to the young Earth's surface and flashed Ocean waves steam. This was the beginning of a fantastic rainstorm that, with the passage of time, gradually filled the ocean basins.
Words to Know Continental margin: Underwater plains connected to continents, separating them from the deep ocean floor. Faults in the ocean floor that form at nearly right angles to the ocean's major ridges. An extinct, submarine volcano with a flat top. Very long underwater mountain ranges created as a by-product of seafloor spreading.
Crevice that runs down the middle of a ridge. Process whereby new oceanic crust is created at ridges. Active or inactive submarine volcano. In mid, however, scientists offered a new theory on the how the oceans possibly filled in.
The National Aeronautics and Space Administration's Polar satellite, launched in earlydiscovered that small comets about 40 feet 12 meters in diameter are bombarding Earth's atmosphere at a rate of about 43, a day.
These comets break up into icy fragments at heights to 15, miles to 24, kilometers above ground. Sunlight then vaporizes these fragments into huge clouds, which condense into rain as they sink lower in the atmosphere. Scientists calculate that this cosmic rain adds one inch of water to Earth's surface every 10, to 20, years.
This amount of water could have been enough to fill the oceans if these comets have been entering Earth's atmosphere since the planet's beginning 4. Ocean basin Ocean basins are that part of Earth's surface that extends seaward from the continental margins underwater plains connected to continents, separating them from the deep ocean floor.
Basins range from an average water depth of about 6, feet 2, meters down into the deepest trenches. Ocean basins cover about 70 percent of the total ocean area. The familiar landscapes of continents are mirrored, and generally magnified, by similar features in the ocean basin.
The largest underwater mountains, for example, are higher than those on the continents. Underwater plains are flatter and more extensive than those on the continents.
All basins contain certain common features that include oceanic ridges, trenches, fracture zones, abyssal plains, and volcanic cones. Enormous mountain ranges, or oceanic ridges, cover the ocean floor. The Mid-Atlantic Ridge, for example, begins at the tip of Greenland, runs down the center of the Atlantic Ocean between the Americas on the west and Africa on the east, and ends at the southern tip of the African continent.
At that point, it stretches around the eastern edge of Africa, where it becomes the Mid-Indian Ridge. That ridge continues eastward, making connections with other ridges that eventually end along the western coastline of South and Central America.
Some scientists say this is a single oceanic ridge that encircles Earth, one that stretches a total of more than 40, miles 65, kilometers. In most locations, oceanic ridges are 6, feet 2, meters or more below the surface of the oceans.Ocean Climate.

About: Nice crisp and clean ocean wave sound effect normalized and eqd for a great 1 minute sound clip. Title: Crisp Ocean Waves Uploaded: License: Attribution Recorded by Mike Koenig File Size: MB Downloads: Waves are the forward movement of the ocean's water due to the oscillation of water particles by the frictional drag of wind over the water's surface.
Waves have crests (the peak of the wave) and troughs (the lowest point on the wave). The wavelength, or horizontal size of the wave, is determined by.
