Explain the impact of the westward expansion of the white settlers in the USA.

The story of agrarian expansion is closely connected to the westward movement of the white settlers who took over the land. After the American War of Independence (1775 to 1783) and the formation of the United States of America, the white Americans began to move westward. The impact of westward expansion were as follows:
The settlers slashed and burnt forests, pulled out the stumps, cleared the land for cultivation, and built log cabins in the forest clearings. Then they cleared larger areas, and erected fences around the fields’ They ploughed the land and sowed corn and wheat.
In the early years, the fertile soil produced good crops. when the soil became impoverished and exhausted in one place, the migrants would move further west, to explore new lands and raise a new crop. After the 1860s, the settlers swept into the Great Plains across the River Mississippi. Thereafter, this region became a major wheat-producing area of America’
