What is meant by carbonisation? |
| Answer» Carbonisation is the slow process of conversion of dead vegetation into coal. Scientists believe that about 300 million years ago, dead vegetation was overrun by soil. As more soil got deposited over the it, more pressure was exerted on this humus. Humus, at this stage, is called peat, the inferior quality of coal. As this went deeper and deeper (due to the weight from above), the peat began to experience more and more pressure from above and higher temperature from under. This compressed the peat and better varieties of coal were produced i.e. lignite and bituminous to anthracite (best) coal. | |
