How does the rock cycle continuously recycle Earth's materials?
The rock gets reused over, and over again, for instance: Rock gets formed into sand, then sand can get pressed hard, and form sandstone, then the stone would weather down and form sand again. BOOM!
How can sedimentary rock become metamorphic?
Heating and pressure
Is diamond a metamorphic rock why?
Diamond is not a metamorphic rock. It is a mineral composed of carbon that forms under high pressure and temperature in the Earth's mantle. Diamonds are then brought to the surface through volcanic activity.
Is helium a liqiud or a solid or gas?
Helium is a gas at room temperature and pressure. It can be liquefied at very low temperatures (-269°C) and becomes a liquid at that point. Helium does not exist in a solid state under normal conditions.
What type of rock was slate rock before it was slate rock?
Slate is fine sedimentary mud that has been subjected to immense pressure over a very long time.
Can rocks be recycled?
Any rock can become a sedimentary rock (even another sedimentary rock) is it is broken down by erosion, and the resulting sediment is then redeposited, undergoes compaction and consolidation and then lithification (lithification is just the process of becoming a rock)Any rock can become a metamorphic rock if it is subject to sufficient pressure and temperature as a result of deep burial (which will result in both high heat and high pressure) or mostly pressure e.g from the pressure of two continental plates colliding.examples - mudstone under high pressure becomes slateLimestone under moderately high temperature and pressure becomes marble.Granite under intense pressure and Temperature short of actual remelting becomes a gneiss, if the greiss undergoes even greater pressure and temperature it can become a schist.Finally, any rock subject to sufficient temperature as a result of very deep burial will melt, become magma, and ofthe magma them eventually cools enough to crystallise you have a new igneous rock
Does an increase in pressure make magma cool?
Pressure does not change the temperature of rocks, but it does change the melting point. A rock that is under a lot of pressure, even if it is very hot, will stay solid, even if that same rock at the same temperature under lower pressure would be melted. This happens because intense pressure can hold the structure of the minerals together more easily, in a more solid form.So, with an increase in pressure, the melting point of a rock also increases.

What is the process by which new rock forms from old rocks?
There are several ways by which old rocks can become "new" rocks, all of which are described by the rock cycle. A rock, no matter what class it falls under, can become igneous, metamorphic, or sedimentary. When melted and then re-cooled, a rock become igneous. When exposed to very high temperature and pressure, the rock becomes metamorphic. When weather or eroded by wind, water, etc., and then lithified (cemented together), the rock becomes sedimentary. Again, any rock can go from one class to the other, or in some cases become a new rock of the same class.
Can metamorphic rock become sedimentary rock?
by heat and very great pressure
How can sedimentary rock become metamorphic?
Heating and pressure
Is obsidian a sedimentary rock igneous rock or a metamorphic rock?
obsidian is an igneous rock, it is not formed from sediment, or a rock going under heat and pressure for the second time it is formed when a volcano erupts and it cools very quickly giving it a smooth glossy surface like glass.
What happens to rock when it is exposed to very high temperature?
Rock exposed to very high temperature and pressure will soften or melt.
What happens when rock and water under the crust become very hot?
When rock and water under the crust become very hot, the water can turn into steam, creating pressure. This can lead to volcanic activity, such as eruptions and geysers. The heat may also cause the rock to melt and form magma, which can rise to the surface and create volcanic eruptions.
How can one type of rock be changed to another type of rock very quickly?
Very quick (depending on one's definition) metamorphism of rock would only occur under extreme and near instantaneous changes to a rock's environment. An example would be the effects on surface rock from a large meteor impact, with the metamorphism occuring from the accompanying high temperature and pressure.
Why would sedimentary rock have to become metamorphic rock before it becomes magma?
It wouldn't have to in the case of an instant melting from a meteor impact. Normally though, the evolution of a magma from sedimentary rock would include a very long process involving the gradual introduction of heat and/or pressure, causing the sedimentary rock to first metamorophose into a different type of rock.
Is diamond a metamorphic rock why?
Diamond is not a metamorphic rock. It is a mineral composed of carbon that forms under high pressure and temperature in the Earth's mantle. Diamonds are then brought to the surface through volcanic activity.
