Final answer:
The relationship between population growth towards the end of the Middle Ages and a movement to colonize new lands was driven by the need for more space to relieve urban overcrowding and more resources to supply a growing economy.
Step-by-step explanation:
The relationship between population growth towards the end of the Middle Ages and a movement to colonize new lands can be attributed to the need for more space to relieve urban overcrowding, as well as the need for more resources to supply a growing economy.
As the population of Europe grew during this time period, the limited resources and overcrowding in urban areas created the desire to explore and settle in new lands.
Additionally, the colonization of new lands provided an opportunity for the European powers to access untapped resources and expand their economies.
