The ocean may be a continuous body of salt water that's contained in enormous basins on surface. Once viewed from area, the predominance of the oceans on Earth is instantly apparent. The oceans and their marginal seas cover nearly 71% of surface, with a mean depth of 3,795 meters (12,450 feet). The exposed land occupies the remaining 29% of the planetary surface and encompasses a mean elevation of only 840 meters (2,756 feet). Actually, all the elevated land might be hidden below the oceans and Earth reduced to a smooth sphere that may be completely coated by endless layer of seawater 2,686 meters (8,812 feet) deep. This can be referred to as the sphere depth of the oceans and serves to underscore the abundance of water on surface. Earth is exclusive within the scheme attributable to its distance from the Sun and its amount of rotation. These mix to subject Earth to a radiation level that maintains the earth at a mean surface temperature of 17°C (62.6°F) which varies very little over annual and night-day cycles. This mean temperature permits water to exist on Earth altogether 3 of its phases - solid, liquid, and gaseous. No alternative planet within the scheme has this feature. The liquid part predominates on Earth. By volume, 97.957% of the water on the world exists as oceanic water and associated ocean ice. The gaseous part and droplet water within the atmosphere represent 0.001%. Water in lakes and streams makes up0.036 %, whereas groundwater is 10 times more abundant to 0.365 percent. Glaciers and ice caps represent 1.641% of Earth's total water volume.
Water unendingly circulates between these reservoirs in what's referred to as the hydrologic cycle that is driven by energy from the Sun. Evaporation, precipitation, movement of the atmosphere, and also the downhill flow of river water, glaciers, and groundwater keep water in motion between the reservoirs and maintain the hydrologic cycle. The large range of volumes in these reservoirs and also the rates at that water cycles between them mix to create necessary conditions on Earth. If little changes occur within the rate at that water is cycled into or out of a reservoir, the amount of a reservoir changes. These volume changes could also be comparatively massive and speedy in a little reservoir or little and slow in a large reservoir. A little proportion modification within the volume of the oceans might produce an outsized proportional modification within the landice reservoir, thereby promoting glacial and interglacial stages. The speed at that water enters or leaves a reservoir divided into the reservoir volume determines the duration of water within the reservoir. The duration of water in a reservoir, in turn, governs several of the properties of that reservoir.
The distribution of oceanic extent with 5° increments of latitude shows that the distribution of land and water on surface is markedly totally different within the Northern and Southern hemispheres. The hemisphere could also be known as the water hemisphere, whereas the Northern hemisphere is that the land hemisphere. This is often very true in the temperate latitudes.
This spatial property of land and water distribution between the Northern and Southern hemispheres makes the 2 hemispheres behave differently otherwise in response to the annual variation in radiation received by Earth. The Southern hemisphere shows only little amendment in surface temperature from summer to winter at temperate latitudes. This variation is controlled primarily by the ocean's response to seasonal changes in heating and cooling. The Northern hemisphere has one change in surface temperature controlled by its oceanic space and land areas.
