The process is always ongoing, but a complete transformation from one type to another could take millions of years or more.
the heat put so much pressure on the rocks that it gets so hot to change colour
Geology is the study of the earth. Since much of the earth is made up of rocks, most geologists spend time studying how the rocks change over time, along with their history and formation.
The temperatures are much higher. This cycle has seen about 10 degrees of warming overall since it began ten thousand years ago. All but about a half a degree of this occurred before man started banging rocks.

Normally when sedimentary rocks are squashed and heated they do indeed change, they become metamorphic rocks. e.g. mud will be turned into slate - limestone into marble etc.As the metamorphic temperature and pressure increase still further, most sedimentary rocks end up as Granulites or Banded Gneisses which look very much like igneous rocks (Granites).In the extreme, sedimentary rocks can melt, and these melts will form new magmas which will eventually harden to form new igneous rocks.

Concrete is a man-made conglomerate composed of pieces of rock in a matrix of cement, which is itself made from limestone. It is just as much part of the rock cycle as any naturally occurring rocks.
No. Moon rocks are much like the rocks on Earth.
rocks and minerals ca
2pac rocks :) 2pac rocks :)
as the plates become heavier with mountains and such, they sink slowly into th mantle where there is enormous pressure. as th mantle burns th underside of th plate, th plate becomes lighter; allowing th mantles great heat output 2lift th plate again
theres no such thing as gold rocks
