Answer:
Factories were built near natural resources, as the transportation of raw materials for production was limited.
Explanation:
Transportation raw materials from the source into the factories require cost of distribution (from the purchase of vehicles, labors, and gas). In order to cut down this cost, factories often built their buildings as close to the source of materials as close as possible.
This principle still exist even until today.
For example, many factories that require the use of a lot of steel that exist in United States were built in Indiana because that state has high reserve of metals.
