What is one possible reason why there was a lower rate of long-distances exchanges in the Americas?

The geography and environment affected the way people of this time period traded and who they traded with. Geography played a part in who these countries or civilizations traded with. Some didn't have the right goods or domestication. An example would be the Americas. Geography played a part by putting obstacles in trader's ways. Rivers, oceans, mountains, thick forest/jungles, etc. These all affected how widely they could trade. The environment played a role by helping transport goods. Such as the monsoons which where seasonal winds in the Indian ocean that blew eastward in the summer months, and westward in the winter months. This helped with overseas travel and trade.

In the Americas, they had trouble trading due to several conditions. First was that the Americas had trouble domesticating animals. They couldn't domesticate animals and animals were a major way in which goods where traded by land. Americas where also limited to who they talked and traded with. They had little contact with further countries thus not trading. They didn't have a clear writing system. They couldn't contact these far away countries because they had no writing system and no way of getting it there do to their absence of domestication.

In Afro-Eurasia, all agrarian civilizations were linked together into a vast interconnected network by the beginning of the Common Era. This network involved not only the trading of material goods, but also the trading of social, religious, and philosophical ideas, languages, new technologies, and disease. The most important exchange system that existed anywhere during the Common Era is known today as the Silk Roads, but significant smaller connections developed much earlier between many of the agrarian civilizations.

Not all these connections were based on trade. Warfare is common to all agrarian civilizations, so conflict was also a powerful way of connecting civilizations. It was through warfare that the Romans eventually connected many of the peoples of Afro-Eurasia. Centuries later, Muslim armies quickly constructed a vast Islamic realm that stretched from Europe to the borders of the Tang dynasty's empire, deep in central Asia. Although these military relationships were important in establishing connections, the most influential connections of the era were built through trade.

Trade was important from the beginning. As early as 2300 BCE, civilizations in Mesopotamia, Egypt, and the Indus Valley were involved in commercial relationships. The Silk Roads enabled these early small-scale exchanges to expand dramatically, leading to even more significant changes in human history, and to intensive collective learning.

The Silk Roads are the supreme example of the interconnectedness of civilizations during the Era of Agrarian Civilizations. Along these often difficult routes, through some of the harshest geography on Earth, traveled merchants and adventurers, diplomats and missionaries, carrying their commodities and ideas enormous distances across the Afro-Eurasian world zone. Each category of exchange was important, and, as a result of this interaction, Afro-Eurasia has preserved a certain underlying unity, expressed in common technologies, artistic styles, cultures and religions, and even in disease and immunity patterns.

Other world zones also had their early exchange networks, but none on the scale of the Silk Roads. American trade networks happened over long distances, crossing diverse geographic regions — from the Andes through Mesoamerica and up into North America. But American networks were much smaller and less varied than those of the Silk Roads, probably because the jungles of the equatorial region acted as a barrier. Because of the Silk Roads, Afro-Eurasia was much larger in population, much more technologically dynamic, and also much more interlinked through trade and exchange than the other three world zones were. This is a particularly important distinction because, when the different zones finally collided after 1492, the societies of Afro-Eurasia were quickly able to dominate the rest of the world. And that in turn explains why the modern revolution that followed was destined to be led by Afro-Eurasian peoples, not those from the Americas.
