What term describes the exchange of crops, livestock, and diseases between the Americas and Europe after 1492?

• A. Silk Road
• B. Mercantilism
• C. Columbian Exchange
• D. Commercial Revolution

Answer: (C)

The exchange of crops, livestock, and diseases between the Americas and Europe after 1492 is known as the Columbian Exchange. After Columbus’s voyages, crops native to the Americas such as maize, potatoes, tomatoes, and cacao spread to Europe, Africa, and Asia, while Old World crops like wheat, sugarcane, and grapes moved to the Americas. Animals such as horses, cattle, pigs, and chickens also crossed the Atlantic, transforming agriculture, transportation, and everyday life on both sides. At the same time, diseases like smallpox, measles, and influenza spread to Native American populations with devastating consequences, while other pathogens or ideas moved in the opposite direction. This term captures the broad, intercontinental transfer that fundamentally altered ecosystems, diets, and societies worldwide following contact in 1492. The other terms refer to different concepts: the Silk Road is an ancient trade network between Europe and Asia; mercantilism is an economic policy focus on accumulating wealth; and the Commercial Revolution describes broader European economic changes, not this specific cross-Atlantic exchange.
