Answer: The Industrial Revolution sparked a greater need for cheap raw materials
Explanation:
The Industrial Revolution was the improvement of production processes in Europe such that goods were being produced way more efficiently than before. This meant that industrial goods could be mass produced in higher quantities.
To produce manufactured goods however requires raw materials which was lacking in Europe at the time so they sought to get these materials from other places and cheaply if they could. They therefore colonized areas rich in raw materials such as Africa to get these materials at low low prices.
