WORLD HISTORY

Detailed explanation-1: -Early mills had run successfully with water power, but by using a steam engine a factory could be located anywhere, not just near water. Water power varied with the seasons, and was not available at times due to freezing, floods and dry spells.

Detailed explanation-2: -The steam engines were being used to run machines in factories instead of water power. Now factories could be built farther away from water sources. A steam engine could be built to be used anywhere. As time passed, more and more people left farms to work in factories that were located in cities.

Detailed explanation-3: -The first steam engines, like the engine invented by Thomas Newcomen, were used to pump water from coal mines. Later engines, such as the engine of James Watt, created in 1765, increased the efficiency and convenience of the steam engine.

Detailed explanation-4: -The steam engine, either used on its own or as part of a train, is the iconic invention of the industrial revolution. Experiments in the seventeenth century turned, by the middle of the nineteenth, into a technology which powered huge factories, allowed deeper mines and moved a transport network.
