The fossil fuel, Coal and the gemstone, jet are formed from ancient plant materials. Jet is a type of lignite.
Rock
Diamond is a mineral form of carbon. It is not a metamorphic rock, but a mineral formed from extreme heat and pressure.
The rock would be limestone, the mineral would be calcite.
One of the softest rocks is Talc. Talc is a mineral not a rock!Minerals are pure, rocks can be formed from one or more minerals. A piece of talc is a rock formed of a single mineral.Clays, are rocks and can be very soft.
Gypsum is a mineral that was formed by layers of sediment , fine particles, that were deposited over a period of time, and then subjected to geologic forces.
No, halite is not an organic rock. It is a mineral composed of sodium chloride (NaCl) and forms through the evaporation of salty water. Organic rocks are formed from the accumulation of organic materials, such as plant or animal remains.
Rock
Sedimentary rock
This is the mineral (not rock) halite.
None, it is a plant.
Diamond is a mineral form of carbon. It is not a metamorphic rock, but a mineral formed from extreme heat and pressure.
You say it as ' Igneous ROCK ' and ask whether it is a rock..
COAL
A naturally occurring solid mass of mineral or mineral-like matter is known as a rock. Rocks are composed of minerals or mineraloids and can vary in composition and characteristics depending on how they were formed.
Igneous (formed from molten rock), metamorphic (formed from metamorphism of preexisting rock), sedimentary (formed from cementation or compaction of sediments, mineral precipitation, or organic material).
Two types of rock formed by conduction of energy are igneous rock, which is created from the cooling and solidification of molten magma, and metamorphic rock, which forms when existing rocks are subjected to high temperatures and pressures. A mineral formed through this process is garnet, which often forms in metamorphic rocks and can indicate the conditions under which the rock was formed.
The word that rhymes with "role" and means black burnable mineral is "coal." Coal is a combustible black or dark brown rock consisting mainly of carbonized plant matter, found mainly in underground deposits and widely used as fuel.
