Sedimentary, Igneous, and Metamorphic rocks are the 3 types of rocks.
All rock types can be formed from any other rock type.
River rock can be composed of any rock type, or any combination of rock types.
selenite is sedimentary. But selenite is really a mineral not a rock. It can be found in any rock type
The lava can cool in to any type of rock it depends on how it cools. And the type is igneous rock.
rock is melted to form molten rock, then as the lava hardens, it forms any type of igneous rock
Any type of color it depends on the facture of the rock..................
The protolith of a metamorphic rock can be any pre-existing rock type, such as shale, limestone, basalt, or granite. The type of metamorphic rock that forms from a protolith depends on factors like temperature, pressure, and the mineral composition of the protolith.
A metamorphic rock.
Any rock can undergo metamorphism, be it sedimentary, igneous or even the transformation of one type of metamorphic rock to another.
I don't think rocks can be any colour because a group of the same type of rock contain the same minerals which would make all that type of rock the same colour
Sandstone (any colour) is a sedimentary rock.
Nonfoliated rock
