Law of cross-cutting relationships

it is a metamorphic rock
there are 4 bill bob and jerry and the one in abi's head she likes to call a brain Igneous, Sedimentary, and Metamorphic.
Usually it is sedimentary rock that is changed into metamorphic - however it is entirely possible for igneous rock to become metamorphic as well. Metamorphic means different form, and in the geological since it mean rock that has been changed by heat and pressure. Now there isn't too much that can be done to igneous rock to change it chemically, by heat and pressure. But it can undergo physical distortions.
Sometimes magma pushes, or intrudes, into cracks in existing rocks. When the melted rock cools and solidifies, the resulting feature is called an igneous intrusion. This image shows metamorphic rock in Death Valley, California, cut by a darker igneous intrusion. The principle of cross-cutting relationships states that an igneous intrusion is always younger than the rock it cuts across.
its igneous and sedimentary and metamorphic
metamorphic because it melts the rock and forms another
the fossils would be turned into another rock if it was in a metamorphic rock or igneous rocks. it requires a blanket of sediment
igneous
gravel is a limestone which can be igneous or metamorphic but almost all is metamorphic
Graphite is a mineral, not a rock that is classified as metamorphic, igneous or sedimentary.
milky quartz is either metamorphic or igneous
It is generally igneous, but can be found in metamorphic rocks.

the three major rocks are igneous, sedimentary, and metamorphic rock. igneous- volcanic rocks sedimentary- rocks with layers on top metamorphic- rocks that formed to another rock
