The motion of molecules in matter increases with temperature. Molecular collisions in a warmer state have more energy than the collisions in a cooler state, tending to increase the volume and therefore reduce the density for a fixed mass.
The water from a melted glacier is less dense than the water of the seas.
In the Mediterranean Sea the cool dense water sinks under less dense water which is called density current.
When a mass of more dense water sinks beneath less dense water, it creates a process called deep-water formation. This vertical movement helps in the redistribution of heat and nutrients in the ocean, playing a crucial role in ocean circulation and global climate regulation.
Dense
Cooler material is more dense and hotter material is less. This means that plates become more dense as they cool.

Heavy rainfall makes water less dense because an increase in salinity leads to an increase in density. Rain does not contain any salt. Therefore heavy rainfall makes ocean water less dense. =)
The water from a melted glacier is less dense than the water of the seas.
Ice is less dense than water.

El Nino waters are less dense because the waters are warmer and warm water is less dense than cool water. Also, it constantly rains over the ocean during the El Nino, and rain water is less dense than ocean water.
Warm water is less dense than cold water.
In the Mediterranean Sea the cool dense water sinks under less dense water which is called density current.
When cool dense water sinks, it becomes more dense because the cooler temperature causes the water molecules to contract and become more tightly packed together. This increased density allows the water to sink below warmer, less dense water layers.
Water is an exception to this rule as it becomes less dense when it freezes and forms ice. This is due to the unique arrangement of water molecules in ice compared to liquid water, causing it to expand and become less dense.
When a mass of more dense water sinks beneath less dense water, it creates a process called deep-water formation. This vertical movement helps in the redistribution of heat and nutrients in the ocean, playing a crucial role in ocean circulation and global climate regulation.
An iceberg floats in the ocean because it is less dense than the water it displaces. Ice has a lower density than liquid water because of its crystalline structure, which allows it to float on the surface.
