What different things can crack a rock?
Anything as dense or more dense than the rock. Rocks, sledge hammers, chisels, etc
Why does hot coffee make you cooler on the hot summer day?
It makes you sweat more and cools your blood
What size crystals result from fast cooling?
When a magma cools down, it becomes a solid. Various atoms "prefer" to be arranged in a crystallic way. So when a magma cools down, crystals start to form and grow. Crystals only grow at their edges, so to make the crystal grow larger, it would need more time to do so. Magma's that cool slower have more time for the crystals inside them to grow, so the crystals will be larger, compared to a magma that cools quicker, or even a magma that comes out of the ground (then called a lava).
What is the difference between igneous rock that cools above and igneous rock that cools below ground?
That depends on where it cools. Igneous rock forms from magma or lava (there's a difference!) cools and hardens. Extrusive igneous rock forms above the earth's crust, like when the lava from a volcanic eruption hardens. Intrusive igneous rock cools inside the earth when conditions change and the area around the magma cools allowing the magma to cool.
What does Canada's population distribution look like?
dense at bottom of Ontario and quebec and more spread out the higher you go.
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 it tends 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.
