Which process is anthracite coal formed from bituminous coal?
metamorphism
How is black and brown coal produced?
Coal is formed by the burial and heating of large quantities of organic matter. Brown coal is a low-grade form of coal, formed by moderate burial and pressure. Black coal is formed by increasing pressure and temperature, removing more of the volatiles and resulting in a more carbon-rich coal.
How coal are formed by layer to layer?
what coal is is layers of ancient dead plants so for every layer of dead plants is another layer of coal that is formed
What phases does coal go through before it forms a diamond?
A diamond is not formed from coal. Diamond and coal are both allotropes of carbon, and are formed by different processes.

What are the four stages of coal formation.?
The materials formed at each step of the process are 1) Peat 2) Lignite 3) Sub-Bituminous and Bituminous Coal 4) Anthracite (may also form from oil) The final stage, which most coal does not reach, is graphite or pure carbon.
Was coal first formed just after pterodactyls became extinct?
Most coal formed during the Carboniferous, between 358.9 and 298.9 million years ago, however some coal has formed during most of Earth's history. Pterodactylus lived between 150.8 and 148.5 milion years ago. Thus, most coal formed 150 million years before Pterodactylus lived, but some coal was forming while and even after the existence of Pterodactylus.

A metamorphic rock formed from coal?
Anthracite, a variety of coal, is formed from the metamorphosis of bituminous coal through natural processes of heat and pressure deep underground.
