what is the difference between???

Question

what is the difference between the ocean and the sea andd why dose the tide go out and then come back in dose it do it with both ocean and the sea

Answer 1

Geologically, an ocean is an area of oceanic crust covered by water. Oceanic crust is the thin layer of solidified volcanic basalt that covers the Earth's mantle where there are no continents.

sea is a large expanse of saline water connected with an ocean, or a large, usually saline, lake that lacks a natural outlet such as the Caspian Sea and the Dead Sea. The Sea of Galilee is a small freshwater lake with a natural outlet, but the term was applied to it anyway. The term is used colloquially as synonymous with ocean, as in the tropical sea or down to the sea shore, or even sea water referring to water of the ocean. Large lakes are sometimes referred to as inland seas, such as the Great Lakes. Many seas are marginal seas.

The tide is the cyclic rising and falling of Earth's ocean surface caused by the tidal forces of the Moon and the Sun acting on the Earth. Tides cause changes in the depth of the sea, and also produce oscillating currents known as tidal streams, making prediction of tides important for coastal navigation (see Tides and navigation, below). The strip of seashore that is submerged at high tide and exposed at low tide, the intertidal zone, is an important ecological product of ocean tides.

The changing tide produced at a given location on the Earth is the result of the changing positions of the Moon and Sun relative to the Earth coupled with the effects of the rotation of the Earth and the local bathymetry (the underwater equivalent to topography). Though the gravitational force exerted by the Sun on the Earth is almost 200 times stronger than that exerted by the Moon, the tidal force produced by the Moon is about twice as strong as that produced by the Sun. The reason for this is that the tidal force is related not to the strength of a gravitational field, but to its gradient. The field gradient decreases with distance from the source more rapidly than does the field strength; as the Sun is about 400 times further from the Earth than is the Moon, the gradient of the Sun's field, and thus the tidal force produced by the Sun, is weaker

Answer 2

First of all (just to be picky) , it's does, not dose.

Both sea and ocean are comprised of salt water. A sea is a division of an ocean - and directly connected to one - that is partially surrounded by land.

The tides come and go due to the gravitational influence of the moon. All bodies of water are affected by the moon - some are just more noticeable than others.

Hope that helps.

Answer 3

No difference. Just how some people who had nothing better to do classified it. Tides are due to the gravitational pull of the moon. The sun affects it somewhat too. Seas, oceans, bays, straits, huge lakes are all affected by tides.

Answer 4

Sea dont crash onto the beach, and ocean does. So ocean is right at the beach its whereever the lands are. Sea is where you cant see lands around.
