Where cool dense water sinks does it become more dense?
In the Mediterranean Sea the cool dense water sinks under less dense water which is called density current.
Why do the layers of atmosphere become less dense as you go higher?
because the air mass decreases
Is molten rock more dense than solid rock?
No. Molten rock expands due to heat as the molecules get excited, therefore it is less dense than solid rock.
Warm air rises because it is?
Warm air rises because it is less dense than colder air. As gases get warmer they expand that the molecules become farther apart causing it to become less dense and therefore, lighter per unit squared, this is why it rises.
Magma tends to rise toward Earth's surface principally because?
Magma tends to rise towards Earth's surface primarily because rocks become less dense when they melt. The hotter the magma, the more the rocks are likely to "float," if you will.
When heat loses its heat does it become less dense and sink?
When air loses its heat it actually becomes more dense and sinks which starts a convection current
When air loses its heat becomes less dense and sinks?
no
Do diamonds become less dense when heat is added?
Yes. They do become less dense provided that the diamond melts. The particles in liquid are less close to each other as compared to in a solid.
Do plates become more dense or less dense when they become cooler?
Cooler material is more dense and hotter material is less. This means that plates become more dense as they cool.
Do convection currents form in the mantle when heated materials become more dense?
Actually, heated materials are less dense. When heat is applied to a substance such as liquid, it becomes less dense. It is this less dense and heated material that rises because it weighs less. The part of the mantle that is more dense would be any substance that is cooling and is sinking down.
Does polar water diluted by meltings ice become more or less dense?
less denser than
If the mass of a fixed volume of air increases does the density become more or less dense?
less dense
Would the density in liquid become more dense or less dense when thermal energy is added?
"less"
What does heat makes air do?
Heat makes air less dense and therefore rise.
How does heating or cooling a substance affect density?
For most substances over all temperatures as you heat a substance it will become less dense and as you cool it the substance will become less dense. But as with any law there exceptions. Liquid sulphur for example will become less dense as it is heated up to a certain point and then as you continue to heat it the sulphur becomes more dense. But the most noteable exception is water. As water cools from a vapour to a liquid and is then further cooled as a liquid it becomes more and more dense until it reaches 2 degrees C. Then as water cools below this point it becomes less and less dense until it starts to solidify. At this point it becomes less dense. Water is one of very few substances whose density as a solid is less than when it is in a liquid state. It is a good thing to or we would never have invented hockey if the ice had been on the bottom of the pond.
Are rocks changed by metamorphism less dense?
That depends on the rock and the type of metamorphism is underwent. Some rocks become more dense, some become less.
How do bones become less dense?
by drinking less milk or a calcium defficency
