Step-by-step explanation:
The pros of living in America's frontier lands included opportunities for economic growth and land ownership. Settlers had access to vast amounts of land which they could cultivate for farming or use for other purposes. They also had the potential to acquire wealth through mining and other natural resources.
However, there were also cons to living in the frontier lands. Settlers faced hardships such as harsh weather conditions, isolation from established settlements, and conflicts with Native American tribes. They had to build their own homes, provide their own food, and handle other challenges that came with living in remote areas.
