Question

Which type of coal is formed from exposure to the lowest temperatures and pressures?

peat

anthracite

lignite

bituminous

Answer 1

lignite

Step-by-step explanation:

Burial and accumulation can occur for several thousands of years, producing several meters of partially decayed plant matter known as peat. When this peat is deeply buried, water and other compounds is squeezed out from the increasing pressure and the lowest quality of coal, lignite, begins for form.
