Why was the south part of Carolina more prosperous than northern part?

This statement is not accurate. Historically, prior to the American Civil War, the southern part of Carolina (referring to the state of South Carolina) was indeed more prosperous than the northern part. This was primarily due to the plantation economy based on cash crops like cotton and rice, which thrived in the warmer climate of the southern regions. However, after the Civil War, the economic dynamics changed, and the northern part of the state experienced significant growth and prosperity, particularly in industries such as textiles and manufacturing.
