3. explain how the silk road led to diffusion

Explanation:

Answer:

1. Global trade facilitates movement of goods, ideas, technologies, and cultural practices between regions, as merchants and travelers carry these elements across borders, spreading them to new populations and causing diffusion.
2. For Europe: It brought new staple crops like potatoes and corn, boosting food production and population growth; precious metals from Americas increased wealth and fueled mercantilism. For North America: European crops (wheat, grapes) and livestock (cattle, horses) were introduced, transforming agriculture and transportation; European diseases devastated Indigenous populations.
3. The Silk Road connected Eurasian civilizations, allowing merchants, missionaries, and travelers to exchange goods (silk, spices), technologies (paper-making, gunpowder), religions (Buddhism, Islam), and cultural practices between East Asia, Central Asia, the Middle East, and Europe, driving widespread diffusion.
