imperial expansion in the period circa 1450-1750.

Knowledge of the environment stimulated the quest to colonize regions that could provide many natural resources capable of stimulating the empire's economy.

Explanation:

The imperial expansion between 1450 and 1750, refers to the political, economic and social process, which allowed European nations to take over other nations with the intent of promoting the European empire in the economic and even cultural spheres. In that case, European nations exploited the resources that the nations dominated by them could provide.

The knowledge of the environment, allowed the imperial expansion to search for nations in regions that could provide a vast amount of natural resources that would supply the European nation and that would allow a profitable trade between countries.
