Question

Why does cold water sink down below the warm water?​

Answer 1

Answer:

When fluids (liquids and gases) are heated, they expand and therefore become less dense. Any object or

substance that is less dense than a fluid will float in that fluid, so hot water rises (floats) in colder water.

When fluids are cooled, they contract and therefore become more dense. Any object or substance that is

more dense than a fluid will sink in that fluid, so cold water sinks in warmer water. Hot air rises and cold

air descends for exactly the same reason

Answer 2

Explanation:

Cold, salty water is dense and sinks to the bottom of the ocean while warm water is less dense and remains on the surface. Cold water has a higher density than warm water. ... While this geothermal energy is transferred to ocean water along the seafloor, the effect is so small that it's immeasurable by direct means.
