sink below the surface
What else can I help you with?
What does air do when it cools?
It becomes more dense and heavier.
When rock cools it becomes more dense and becomes to?
sink below the surface.
When rock cools it becomes more dense and trends to?
sink below the surface.
Does air lose density when it heats or when it cools?
Air loses density when it heats up because the air molecules become more energetic and spread out, resulting in a decrease in density. Conversely, air becomes more dense when it cools down because the molecules lose energy and come closer together.
Is it true that as oceanic crust moves away from the mid-ocean ridge. it cools and becomes more dense?
True.
Is it true oceanic crust moves away from the mid ocean ridge it cools and becomes more dense?
yes
Why does ocean crust from a mid-ocean ridge subside?
It becomes more dense as it cools, until its density is greater than the asthenosphere below it.
What to do when all the goo goes to the top of a lava lamp?
Turn the lamp off. As it cools, the wax (goo) becomes more dense and will fall to the bottom.
How does a gas change back to a liquid?
Usually this happens when a gas cools. It becomes more dense as the gas particles move more slowly. Eventually it condenses and so it changes back to a liquid.
Why does covection take place?
It takes place in the mantle and moves away and back from the heat of the core. The fluid in the mantle moves away from the core and becomes less dense. Once it cools it comes down and becomes more dense and so on. The tremendous heat inside the core is the is causing the movement.
Is a lava lamp an example of density?
Yes. The bubbles of fluid heat up and expand causing them to be less dense than the clear liquid. That is why it floats. When it gets to the top it cools and shrinks and becomes more dense than the clear liquid.
What forces causes natural convection currents?
Natural convection currents are caused by density differences in a fluid due to variations in temperature. When a fluid is heated, it becomes less dense and rises, creating a current. As the fluid cools, it becomes more dense and sinks, completing the convection cycle.
