Final answer:
The land, climate, and people who settled the southern colonies all contributed to the development of the plantation system.
Step-by-step explanation:
The development of the plantation system in the southern colonies was influenced by three main factors: the land, the climate, and the people who settled there.
The land in the southern colonies was suitable for growing cash crops like tobacco, sugarcane, and cotton. The fertile soil and warm climate provided ideal conditions for these crops to thrive.
The settlers in the southern colonies, mainly wealthy Europeans, established large plantations and relied on enslaved Africans for labor. The high demand for labor at peak planting and harvest times led to the establishment of the plantation system.
