Want this question answered?
A density current is where a warm current floats on top of a cold currentA density current is where a warm current floats on top of a cold currentThe movement of a mass of cold, dense ocean water as it sinks beneath warmer surface water.
upwelling
when water vapor freezes on a cold surface liquid waree forms immediately
upwelling
Upwelling.
Boiling takes place and it leads to the movement of hot water upwards and the movement of cold water downwards.
the movement of deep, cold, nutrient-rich water goes up to the surface. Up-welling can be rising of any liquid. water moving up from the benthic zone
Tropical waters are nutrient poor at the surface. When living things die at the surface they sink to the bottom where they decompose. The nutrients that are released when they decompose stay at the bottom because there's a thermocline--the deep water is cold and the surface water is warm and they don't mix. So the surface waters don't have much algae and stay clearer.
When cool nutrient rich water is driven to the surface by wind, replacing warmer and nutrient depleted water, this is known as upwelling. This stimulates the synthesis of organic compounds and helps fishing productivity.
this is one of my favorites questions because my sisters cusins dog always asked this it is idk

Water is formed as a liquid when steam meets a cold surface.
An upwelling is a current in the ocean that brings deep, cold water to the ocean surface.
When we boil water and expose the steam (water vapor) to a cold surface, it will condense into tiny drops of water on the cold surface. If you can see the 'steam'rising above the water, it has already condensed into tiny droplets of water in the cool air.
If the water is cold, that means that water molecules have small speed, in hot water, molecules have greater speed, thus greater energy, and need less energy than cold water to be kicked out through the surface.
It is called "upwelling" and occurs due to wind-induced surface motion, and often the Coriolis effect.
