Explain how transportation innovations of the time period affected migration patterns in the united states. 99 points ; ]

With the expansion of transportation, it was easier for people to travel westward, allowing the western-population to expand.

In the beginning, during the "Frontier" times, many people did not travel west, because it was dangerous, with diseases, Indian attacks, starvation, etc. However, with the creation of better transportation systems, more people moved westward to start a new life, and, if possible, strike it rich.

    racial conflict and discrimination has existed ever since man learned to kill with rocks and bones. these conflicts arose from disputes between territory, power, wealth, religion, or simple difference. some of the most infamous racial disputes include slavery, the holocaust, and the civil rights movement.

    these listed disputes often resulted in casualties from all sides. riots, wars, imprisonment, and lynching are all commonly associated with racial conflict on severe levels.

      however, racism is an improving issue in recent decades. people are being more accepting and welcoming of diverse populations. though, the world isn't perfect and it will take much more time, if ever, until the world is rid of racism.
