Final answer:
After settlers were granted full ownership of their land, they could purchase additional land from the government or through homestead grants.
Step-by-step explanation:
After settlers were granted full ownership of their land, they could purchase additional land through various means. For example, if settlers had the financial means, they could buy land directly from the government, usually near a navigable river or railroad. They would need to pay the price set by the government, which was typically a minimum of one dollar per acre. Additionally, homesteaders could acquire additional land through homestead grants until the 1880s, although these lands were generally of marginal value and isolated.
