Final answer:
Advances in steam power and water travel, such as steamboats and improved river transportation, enabled the South to rapidly transport its growing cotton exports from 1793 to 1830.
Step-by-step explanation:
The new technology that enabled the south to transport rapidly growing cotton exports between 1793 and 1830 was advances in steam power and water travel, such as steamboats and improved river transportation.
Steam power allowed for faster and more efficient transportation of cotton from inland areas to the ports along the Atlantic seaboard, where it could be shipped to markets all over the world.
This technological advancement revolutionized the ability of Southern farmers and planters to move their cotton harvests to the global market, contributing to the significant increase in cotton production during that time period.
