Question

Which is usually colder, a deep current or a surface current?

Note: I asked Which is usually colder...Not Which is usually warmer!

Answer 1

it all depends. in large bodies of water exist thermoclines. a thermocline is a mass distiction between two layers of water. temperature differences can range sometimes 20 to 30 degrees between layers. In a warmer climate, however, the surface current should be warmer because water absorbs the sun's energy. In colder climates, the water will be warmer at a deeper area because water is an insulator and will get colder at the surface first.

Answer 2

Deep ocean currents are brought about by employing variations in water temperature and salinity. The currents are generated from the forces appearing upon the water like the earth's rotation, the wind, the temperature and salinity variations and the gravitation of the moon. The intensity contours, the coastline and different currents effect the present's path and power. Deep ocean currents are pushed by employing density and temperature gradients. Thermohaline flow, additionally usual via fact the sea's conveyor belt, refers back to the deep ocean density-pushed ocean basin currents. those currents, which pass below the exterior of the sea and are for this reason hidden from instantaneous detection, are referred to as submarine rivers. Ocean currents are measured in Sverdrup with the emblem Sv, the place a million Sv is resembling a quantity pass cost of 106 cubic meters consistent with 2nd

Answer 3

Well, its a matter of relationships. Cold water drops below warm water and thus you get currents. Look at a map of ocean currents and try to predict the temperatures and consider what else could cause upwelling currents, i.e. geography.

Answer 4

surface because its closer to the sun

Answer 5

deep
