Final answer:
The Atlantic slave trade increased the Americas' role in triangular trade by providing a cheap labor force for plantations, leading to increased production of cash crops like sugar, tobacco, and cotton.
Step-by-step explanation:
The Atlantic slave trade had a significant impact on the Americas' role in the triangular trade. The triangular trade was a system of trade routes between Europe, Africa, and the Americas. The arrival of enslaved Africans in the Americas during the Atlantic slave trade provided a cheap and abundant labor force for the plantations, which greatly increased the production of crops like sugar, tobacco, and cotton. As a result, the Americas became the primary source of these cash crops, which were then sent to Europe as part of the triangular trade.
