Final answer:
Improvements in technology on the Great Plains, such as the steel plow, barbed wire fence, and railroads, had significant impacts on settlers.
Step-by-step explanation:
Improvements in technology had a significant impact on settlers on the Great Plains. One major advancement was the development of the steel plow, which made it easier for settlers to cultivate the tough prairie soil. This allowed them to grow crops like wheat, contributing to the region's agricultural success.
Another important technological improvement was the introduction of the barbed wire fence. This helped settlers to protect their land and livestock from encroachment by other settlers and roaming cattle, leading to greater stability and security on the Great Plains.
The expansion of the railroad network was also a crucial technological development. Railroads connected the Great Plains to markets in the East and allowed for the transportation of goods and people. This facilitated the growth of towns and cities, as well as the export of agricultural products.
