Answer : OCEAN
ocean – n
a large body of water constituting a principal part of the hydrosphere
ocean, continuous body of salt water that is contained in enormous basins on Earth’s surface.
When viewed from space, the predominance of Earth’s oceans is readily apparent. The oceans and their marginal seas cover nearly 71 percent of Earth’s surface, with an average depth of 3,688 metres (12,100 feet). The exposed land occupies the remaining 29 percent of the planetary surface and has a mean elevation of about 840 metres (approximately 2,755 feet). Actually, all the elevated land could be hidden under the oceans and Earth reduced to a smooth sphere that would be completely covered by a continuous layer of seawater more than 2,600 metres (8,530 feet) deep. This is known as the sphere depth of the oceans and serves to underscore the abundance of water on Earth’s surface.
Earth is unique in the solar system because of its distance from the Sun and its period of rotation. These combine to subject Earth to a solar radiation level that maintains the planet at a mean surface temperature of about 14–15 °C (57.2–59 °F). Mean surface temperature varies little over annual and night-day cycles. This mean temperature allows water to exist on Earth in all three of its phases—solid, liquid, and gaseous. No other planet in the solar system has this feature. The liquid phase predominates on Earth. By volume, 97.957 percent of the water on the planet exists as oceanic water and associated sea ice. The gaseous phase and droplet water in the atmosphere constitute 0.001 percent. Fresh water in lakes and streams makes up 0.036 percent, while groundwater is 10 times more abundant at 0.365 percent. Glaciers and ice caps constitute 1.641 percent of Earth’s total water volume.
