Which explanation most accurately describes convection within the ocean

Answer

Convection also known as ocean current is a phenomena which takes place within the ocean it takes place due to variation of temperature of oceanic water and due to wind on the surface of water. When temperature of oceanic waters increased that time density of water decreases. Less density water than reached above the cool water and due to wind which blows on the surface water it becomes cool or in other words we can say that water released  its heat to the surrounding environment. when water becomes cool it again shifted in downward direction and less density water  will moves upward. In this way this process will continue.

the gas collects in coils that then becomes a liquid that then flows through the coils inside the refrigerator

their crystal patterns have been disrupted by stress
