Question

What motivated new world colonies to trade goods with each other

Answer 1

Hello! 

Different colonies had different land. So they could grow different crops, which motivated them to trade so that they could have more of different items. They wanted to have a variety of items to please everyone. So I would say it would be because they wanted new items/choices of crops/materials. 

I hope this helped!
