Four changes that were ocurring in the U.S cities between 1850 and 1900 were:
1. There was a lot of <u>migration</u> to big cities. Cities grew enormously because of migration. For example, after the Civil War, Afro Americans migrated to northern cities trying to avoid extreme racism in the south.
2. Development of <u>railroads</u> and trains, there were new railroad lines. There was a development of steel mining, steel was used to construct the new railroads.
3. <u>Architecture</u> changed because most new structures were made out of steel. The city's landscape changed considerably, many new buildings were built.
4. Development of <u>industry</u>, particularly steel. Cities started being populated by industrial workers.
Nice one :)) shame I can't ask them myself. Or can I?
The king and queen of Spain were very much interested in learning more about India and would like spices and jewels, so they funded Christopher Columbus's voyages, but as we all know he ended up in North America, not India.
