<span>most Southerners saw Lincoln's election as a threat to their way of life and the end of slavery</span>
Well, once the Americas were discovered and the colonist found that the soil was agreeable to grow different crops such as tobacco and cotton the colonists realized that they needed people to pick the crops. Originally indentured servants did the hard labor but then when they found that they could get labor by trading goods with African tribal leaders they resorted to importing Africans to the Americas as labor. The tribes in Africa were constantly fighting and whichever side won the losers became the slaves of the winning tribe. However, as Europeans brought valuable things to the continent of Africa such as weapons, salt, gold, and other things the leaders of the winning tribe would give their slaves to the Europeans. There were cases when Blacks captured other Blacks in Africa for the sole purpose of giving them to the European traders. Hopefully this helps. If you haven't see the movie La Amistad, it will explain in more detail what I have written. I learned a lot from that movie. I must warn you the first 5 to 10 minutes are a bit gory. I had a hard time watching that part.
Newton's second law is that every object will move in a straight line and in one direction unless acted on by an outside force.
Hope this helps!
<u>Answer:</u>
(B) “Production and demand decreased with increased oil usage”
This was one of the factors for the decrease in demand for coal.
<u>Explanation:</u>
In 1930s, during the Great Depression period, the market saw a massive decline in the production of coal and a small steady increase in that of oil. One of the major reasons was the availability and price of oil and other natural fuels. The supply rate was higher than the demand rate which kept the prices of oil and other natural fuels low. Cost of mining and producing coal was very high. Lower prices and increased production of oil helped the producers to gain profit. This is one of the factors that helped oil to succeed ahead of coal.
