There are several different issues that cause disagreement between Republicans and Democrats including:
1) Size of the federal government- Republicans prefer a smaller, less involved government while Democrats favor a large, more involved federal government.
2) Taxes- Republicans favor a low tax rate on individuals, corporations, and businesses. Democrats prefer a higher tax rate on wealthier companies and individuals and a lower tax rate for poorer citizens.
It depends on what time period you are referencing with African immigrants. Back in the 1500s, African people came to the Americas because of Slave Trade, but later on, they came to the United States under their own free will. Slave Trade forced African people on ships into the Americas, in which they stayed as slaves or did forced labor in a harsh system.
In the 1900s and later on, African immigrants came to America to seek asylum or safety in the United States because of problems going on in their countries. For example, in Rwanda, in the 1990s, there was some major problems going on such as genocide (mass killing of people) and some people came over to America to escape these hardships.
Also, another way they are different would be their culture that they brought. Their influence of music and African culture was very different as compared to other cultures from Europe.
The three ways in which geography was effected by these voyages are:
- they finally proved that the Earth is round;
- the discovery of new continents and islands;
- mapping;
The voyages of this period of time were extremely important for the geography as a science, as well as for the whole human kind. With them, it was finally proved that our planet is round, and thus those questions and debates were finally given the answer that everyone was looking for for so long. Four new continents and thousands of islands were discovered, and that gave a whole new perspective to the world, its shape, land masses, and water bodies. Since lot of new discoveries were made, and there was an ever-growing number of places discovered, the mapping was crucial, and there was a lot of focus on it that contributed in its development and new techniques of mapping.
