Melt and recrystallize
When long-buried igneous rock is exposed to high temperatures and pressures, it can undergo a process called metamorphism. This transformation alters the mineral composition and texture of the rock without melting it, resulting in a metamorphic rock. The heat and pressure can cause recrystallization of minerals, foliation, and the development of new minerals, depending on the original rock type and the specific conditions of metamorphism. If the temperatures become extreme enough, the rock may eventually melt and form magma.
If exposed to high enough temperatures and pressures, long-buried igneous rock could undergo metamorphism, transforming into a metamorphic rock. This process involves the recrystallization of minerals and the alteration of the rock's texture and composition without melting. The resulting metamorphic rock may exhibit new characteristics, such as increased density and the formation of foliation or banding, depending on the conditions of pressure and temperature.
Melt and recrystallize
Metamorphic rocks form when existing rocks, such as sedimentary or igneous rocks, are subjected to high temperatures and pressures within the Earth's crust. This can occur due to tectonic activity, such as mountain-building processes, or by being buried deep within the Earth's crust.

Melt and recrystallize
If a metamorphic rock is buried deeply in the earths' crust it comes under great pressures and temperatures. If these are great enough to re-melt the rock it ceases to be metamorphic and when it cools, it re-crystallizes into an igneous rock.
Sedimentary rock can be turned into lave or magma by contact with either of the substances or exposure to extreme heat. When the lava or magma cools, it becomes igneous rock.Students who are using wiki.answers.com could be advised that copying word for word is plagerizm.
Sedimentary rock melts, then it cools to form Igneous rock. Hoped this helped. :)

Metamorphic rocks are formed underground through the process of heat and pressure altering existing rocks. When rocks are buried deep in the Earth's crust, they are subjected to high temperatures and pressures that cause their mineral composition and texture to change. This results in the formation of metamorphic rocks from pre-existing igneous, sedimentary, or other metamorphic rocks.
Crude oil is a complex mixture of hydrocarbons that are formed from the remains of ancient marine organisms being buried and subjected to high temperatures and pressures over millions of years.
Oil does not come from rock but is formed when living organisms (lots of them) are buried under high pressures and temperatures under the ground. So oil, is basically, recycled dead animals.
