Step-by-step explanation:
The inventions during the Westward Expansion played a crucial role in the development of the United States.
First, the steamboat revolutionized transportation by enabling faster and more efficient travel on the large rivers. This helped connect different regions of the country and facilitated the movement of goods and people.
The telegraph, on the other hand, transformed communication by allowing messages to be sent quickly across long distances. This improved coordination and information sharing throughout the expanding nation.
Furthermore, the sewing machine revolutionized the textile industry. With the ability to mass produce clothing, the United States became a major center for textile manufacturing, contributing to its economic growth and development.
