Tag: oceanic salinity and oceanic temperature

Precipitation is the main source of potable water available of the earth. Snow, hailstones, rainfall, are the major forms of precipitation.

Oceans provided abundant food resources like fish and salt.

Temperate is one of the major property of seawater. It always varies from region to region. The surface temperature of the sea water decreases from the equatorial area towards the poles. Some factors which effects the temperature of sea water are:-

• Cyclone
• Rainfall
• Salinity
• ocean currents
• pollution

As the salinity of the landlocked seas is more, the temperature of these landlocked seas is higher than the open seas. Aral sea is landlocked sea.

Crude oil and natural gas occur in 'pockets' under the ground. Sometimes the deposits are found under the sea bed. Like other deposits, they are extracted by drilling a hole down through the rocks into the oil or gas. For undersea deposits, the drills are mounted on a platform called a drilling rig.

The movement of ocean waters or ocean currents takes place due to the effect of earth's rotation, wind difference, salinity and density of seawater, etc. The current in the ocean is originated due to the combined effect of all these factors acting internally as well as externally. 

After 2000m, the temperature of the seawater is uniform everywhere. It is around $4 ^oC$ according to depth. And therefore, the water of greater depths does not freeze.

Temperate is one of the major property of seawater. It always varies from region to region. The surface temperature of the sea water decreases from the equatorial area towards the poles.

In mid-latitudinal zones, rainfall is less and the supply of freshwater from various rivers is also low. This zone has the hot deserts of the world.
