Coal belongs to the mineral group called organic minerals because it is primarily made up of organic matter, mainly carbon along with small amounts of other elements.
Coal forms from the remains of plants that have been buried in Earth's crust for millions of years. Over time, heat and pressure from the layers of rock above it compress the plant material, forming coal. This process of transformation from plant material to coal is part of the rock cycle, as coal is a type of sedimentary rock.
Coal is classified as an organic sedimentary rock. It is primarily composed of carbon-containing compounds formed from plant material that has been preserved over millions of years through geological processes.
Coal is not a rock; it is a black or brown sedimentary rock that forms from partially decayed plant matter. It is classified as an organic sedimentary rock rather than an igneous or metamorphic rock.
The origin of diamonds is rock, specifically kimberlite and lamproite volcanic rocks that form deep within the Earth's mantle. Coal is a completely different type of sedimentary rock formed from plant material.
Sedimentary rock.
Obsidian is in the Igneous rock group.
A schist rock belongs in the metamorphic rock group.
Obsidian is in the Igneous rock group.
the answer to the is sedementary
Diamond belong to the Igneous rock group!!
It is a sedimentary rock.
Igneous
Slate is a low-grade metamorphic rock.
I believe it belongs to the group Halides.
Sedimentary Rocks because chalk is pretty much limestone.
Metaconglomerate is a "metamorphic" rock whose parent rock type was a sedimentary rock.
