Which invention resulted in an increase in the demand for coal? a) iron plow b) cotton gin c) steam engine d) internal combustion engine

The correct answer is option C) Steam Engine

Steam Engines were developed in the 1st Industrial Revolution in England. They led to the development of trains which provided fast travel throughout the country.

Steam Engines require the burning of coal to make steam and push machinery. This meant that the Steam Engine and Coal were perfect complimentary products and the increase in demand for one, would automatically increase the demand for the other.

Railway lines completely transformed countries as more and more goods and people could be transported cheaply and quickly.

From England, steam engines and trains spread to Europe, the US and other parts of the world and for the next 150 years, trains became the preferred mode of transport.
