Please don't just copy my answer :) Please just use it as inspiration for your own response.
The 13th amendment not only banned slavery, but had a lot to do, with the economy. There have been many job opportunities that became available due to slave shortages.Any farmer who was unable to afford paying employees had to sell any or all of their land. There were many jobs available, but none were openly available to African Americans. African Americans began finding employment very difficult due to the southern hate for their race.

Latitude and longitude are used to measure how north/south a place is (latitude) and how east/west a place is (longitude.) time zones are very important because the sun sets at different times around the world. For example, the time zone between the United States and Africa is different because when it is day in the United States, it is actually night time in Africa.
