First magma then there is heat and pressure which makes igneous rock then compaction, deposition, and cementation that makes sedimentary rock then more heat and pressure but not enough heat and pressure to melt it but enough to change it to metamorphic rock! and there you have it it's The Rock Cycle
Many ways, really. For example, a continental plate may be submerging underneath another continental plate (a boundary interaction often associated with volcanoes), and in the process, that continental plate that is being submerged, often the ocean floor, changes into metamorphic rock, and if subjected to enough pressure and heat, may become igneous. Or, if two continental plates collide where one plate used to be ocean floor, such as with the Himalayan Mountains, the two plates would jam together. In between these plates, there may be enough heat and pressure to change the sedimentary rock into metamorphic rock.
Metamorphic rocks are buried deep inside Earth. There is enough heat and pressure to change the rocks, but not enough to melt it into magma. Metamorphic rocks can form adjacent to layers of magma, because of the generated heat, however
because water (in massive amounts) is heavy
In short, yes! The melting point of a substance will change based on the air pressure as well as the temperature. In fact, though very unlikely, it's possible for a liquid to solidify if the pressure drops enough and it's cold enough, or if it's warm enough for the liquid to evaporate.
It would become metamorphic rock.
When granite is subjected to enough heat and pressure, it becomes a metamorphic rock called gneiss.
If enough heat and pressure is applied (40000 to 60000 times atmospheric pressure and 900 to 1300 degrees Celsius), granite or any other allotrope of carbon can be turned into diamond.
Limestone/chalk. Limestone has been subjected to heat and/or pressure, it metamorposes into marble. Both limestone and marble are calcium carbonate (CaCO3). Its just that the internal physical structure of limestone is altered.
For a solid to change into a gas, the conditions needed are high enough heat and low enough air pressure.
the heat put so much pressure on the rocks that it gets so hot to change colour
Do you mean blood pressure? Yes it does like for example when you do drugs or something

There was a change in pressure within the cabin. The pen's ink compartment was at higher pressure pressure when you boarded, but the cabin pressure must have decreased enough at altitude to cause the pen to leak.
Not enough oil was replaced. If this is not the case then oil pressure may be low.
