Final answer:
The Cumberland Gap was formed by water erosion, creating a natural pathway through the Appalachian Mountains. Daniel Boone was the first European-American to go through the gap, opening up westward expansion.
Step-by-step explanation:
The Cumberland Gap was formed by water erosion. Over millions of years, the force of flowing water carved out a narrow passage through the Appalachian Mountains. This process created a natural pathway in the region, making it easier for people to travel across the mountain range.
During the European-American settlement, Daniel Boone became the first to traverse the Cumberland Gap in 1775. He blazed a trail known as the Wilderness Road, which allowed for westward expansion and increased migration into Kentucky and other parts of the western frontier.
