What are some of the ways that the physical and natural environment put limits on the directions and locations of trade routes in premodern times? 150 words at least pls

Before the invention of cars or trains there was the issue of transportation throughout the world.

The terrain defined which areas  could get which resources and not the independent people of the region who would wish for something but could not have it because the place where that thing would be is across a mountain range.

This is the reason why ancient trade routes exist that were tried and tested and were known to be easy to walk on.

the crusades are one of the most significant events in the history of europe and the middle east.   they were a series of religious wars carried out by christian crusaders from europe during the timeframe of the middle ages.   beginning in 1095 ce, the crusades saw european knights and noblemen travel to the middle east in an attempt to capture the holy land away from muslim people that had controlled the region for the previous centuries.   the term crusade means ‘cross’.   therefore, the europeans that became crusaders viewed themselves as ‘taking up the cross’.   in fact, many of the crusaders wore crosses on their clothing and armor as they made their pilgrimage to the holy land.
