Warm air is less dense (lighter) than cold air..that is why warm air rises and cold air settles
Ice is a solid less dense than the liquid
No. Molten rock expands due to heat as the molecules get excited, therefore it is less dense than solid rock.
cold ocean waer has more dense than warm water.
No. Magma varies in density, but it will be less dense than a solid rock of the same composition.
Yes.
yes
it rises
Crustal rock is normally less dense than mantle rock.
Warm air is less dense then cold air. But moist air is actually less dense than dry air because water vapor has a lower molecular weight than the oxygen and nitrogen that make up most of the atmosphere.
Hot air is less dense than the surrounding air and therefore it rises. Cold air, on the other hand, is the opposite. It is more dense than surrounding air and sinks.
True... warm water is less dense than cold water.
