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
How do metamorphic rock type forms?
Metamorphic rock is made from a large amount of heat and pressure. Under the serface of the earth this usually takes place very close to the core of the earth, so it is very hot. that creates the heat. Pressure from layers and layers of sediment pileing up, combined with heat, makes a metamorphic rock.
How do volcanoes explode lava?
The molten rock under a volcano, called magma, is under enormous pressure due to the amount of rock on top of it. In many cases there is gas trapped in the magma in a dissolved state. When the magma is exposed to the much lower pressure at or near the surface the gases come out of solution and form bubbles that expand very rapidly, creating an explosion that can pulverize the rock.
Is diamond a metamorphic rock why?
Garnet is a non-hydrous mineral, meaning it will form in environments where there is very little water. During the metamorphosis of a rock, as it's being squeezed and compacted by high pressures and heated by high temperatures, the water is driven out and the minerals that contain water are transformed to minerals with a different chemical composition that do not contain water, such as garnet.
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.

Does shale form from gneiss?
It can, indirectly. Shale is a sedimentary rock. Like many rocks, gneiss can be weathered down to very fine particles to the point that it becomes clay or silt. Those particles can then settle on the bottom of a body of water as mud. Under the pressure of burial, that mud can become shale. However, gneiss can also form from shale. Under long exposure to enormous heat and pressure shale will becomes slate, further heating and pressure will turn slate into phyllite, phyllite into schist, and schist into gneiss.
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.

Under the serface of the earth this usually takes place very close to the core of the earth, so it is very hot. that creates the heat.

What happens to rock when it is exposed to very high temperature?
Rock exposed to very high temperature and pressure will soften or melt.

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.
