What is bituminous coal in geography?

Bituminous coal or black coal is a relatively soft coal containing a tarlike substance called bitumen or asphalt. … Bituminous coal is an organic sedimentary rock formed by diagenetic and sub metamorphic compression of peat bog material.

There are four stages in coal formation: peat, lignite, bituminous, and anthracite.

Why is coal bad for the environment?

The burning of fossil fuels releases greenhouse gases into the atmosphere, increasing levels of CO2 and other gasses, trapping heat, and contributing to global climate change. Coal combustion releases the greenhouse gases carbon dioxide (CO2) and nitrous oxide (N2O) during combustion.
