<span>Saturated fats are solid at room temperature, while unsaturated fats are liquid at room temperature. This is because saturated and unsaturated fats differ in their chemical structures. Saturated fats have no double bond between molecules, which means there are no gaps and the fat is saturated with hydrogen molecules.</span>
The lower density water occurs in the deep zone of the ocean.
This region of water is cold and stable. Cold water has a higher density as the water molecules are packed more closely together, so they occupy less volume. The difference in density of the regions of ocean is responsible for convection currents.
Yes it is true that m<span>ovement of water where density increases underwater causes deep currents.
TRUE. :)</span>
