Question

under which conditions does coal formation take place from plant and animal remains?

a) high temperature and high pressure
b) high pressure and cold surroundings
c) low pressure and high temperature
d) low pressure and cold surroundings​

Answer 1

Answer:

High temperature and high pressure

Explanation:

Coal is fossil fuel or fuel that comes from the remains of prehistoric plants or animals. The formation of coal occurs over millions of years via a process known as carbonation. In this process, dead vegetation is converted into carbon-rich coal under very high temperature and pressure.

Answer 2

a) high temperature and high pressure are responsible for coal formation.

1. Coal is a fossil fuel and hence non renewable source of energy. The burning of coal results in release of carbon dioxide, gas responsible for global warming.
2. Dead remains are firstly converted into peat by action of anaerobic bacteria.
3. Further conditions of increasing temperature and pressure forms lignite which on further availability of such conditions forms bituminous coal and then anthracite.
