Story of Coal

3.1.1 Story of Coal

Description

Quick Overview

This section explains the formation of coal through the process of carbonisation from ancient vegetation.

Standard

The section delves into the origins of coal, tracing its formation from the remains of vegetation buried under layers of soil and transformed by heat and pressure over millions of years. It also highlights coal's various uses and its classification as a fossil fuel.

Detailed

Story of Coal

Coal, a fossil fuel, traces its origins back around 300 million years ago when dense forests flourished in wetland areas. Over time, these forests were buried under soil due to natural processes such as flooding, leading to compression and temperature rise. The remains of the vegetation underwent a slow transformation into coal through a process called carbonisation. Given its carbon content, coal is classified as a fossil fuel, alongside petroleum and natural gas, which were also formed from ancient organic matter.

Key Characteristics and Uses of Coal

Coal is primarily used as a fuel for cooking, generating electricity in thermal power plants, and supporting various industrial processes. By-products like coke, coal tar, and coal gas emerge from coal processing, each having numerous applications ranging from steel manufacturing to being a source for chemical products. However, as an exhaustible resource, its consumption raises concerns about sustainability and environmental impact, calling for responsible usage.

Key Concepts

  • Formation of Coal: Coal is formed from the remains of vegetation through the process of carbonisation.

  • Fossil Fuels: Coal is classified as a fossil fuel, along with petroleum and natural gas.

  • Uses of Coal: Coal is used in various industries, including electricity generation, cooking, and manufacturing products.
