Okie, so, Some new technology that helped change life in the West includes:
- rail roads
- steam power
- sewing machine
- telegraph
There's so much more than that, but those are the main ones.
Explanation:
Railroads made it much easier to transport more goods long distances in a relatively short amount of time.
Steam power made it possible for more factories to be powered, as well as exist. It also lead to inventions such as the steam boats and steam train.
Sewing machines made life on the plains easier. sewing clothes by hand took a loooooong freaking time, but with the sewing machine people (mostly women... only women?) could sew many clothes in the time it took to sew one by hand.
The telegraph enabled quick communication over long distances. It also helped America feel more connected. If something big happened in New York, it would normally take months for the news to reach, say California, but with the telegraph, people could receive news right after, or even while it was happening.
