Geothermal energy is the energy drawn from the earth (geo) by way of the hot rocks that are found there. It is created as a result of the tremendous heating caused by the fission of radioactive elements in the earth's core.
Nobody has even gotten close to directly examining the interior of the Earth. So there is disagreement among geophysicists as to how heated the Earth's core is. However, the speed at which earthquake waves, sometimes known as "seismic waves," move can reveal a lot to scientists about the composition of the Earth.
It is thought that the Earth's core temperature ranges between 5,000 to 7,000 degrees Celsius. That is far colder than the sun's inside, yet roughly as heated as the sun's surface.

The most common method of extracting coal from mines are:
- The most common method of surface mining is open pit mining. This technique is most appropriate for areas with flat terrain, exposing coal while removing soil above the coal layer in batch system. When all the soil above the coal layer is removed, the underlying coal block is exposed and can then be drilled and blown. This process is performed successively, block by block.
- The contour mining method is the most commonly used surface mining technique in steep terrain areas. This method involves removing the soil above the charcoal layer in a standardized way, following the surroundings of a hill or a mountain, for example. This method requires great safety precautions, as it can cause large landslides and serious soil erosion problems. To solve these problems, a variety of methods have been developed over the years to establish limits for mining work.
- The method of mountain mine clearance involves the removal of mountains to expose coal shafts, eliminating sterile areas from mining sites. This practice combines the technology of mining of surroundings with the one of mining in the open sky.
A local or regional level marketing wherein mostly vegetables are cultivated on a large scale with the focus on surrounding markets, is known as truck farming.
