Answer:
The North was an industrial economy by 1860 and the South continued to be an agricultural economy producing cotton, tobacco, sugar and other things. The southern economy relied heavily on slave labor, which was not the case of the North.
In the decades previous to the Civil War (1861-1865), the different administrations imposed high tariffs to foreign products to protect the American- made northern products. This meant that northern products had usually a high price southerners had to pay for; this originated many claims of a preferential treatment which was damaging for the South and disatisfaction.
And of course, there were the rising tensions over the issue of slavery and whether new states should join the Union as free or slavery states.
Explanation:
From lakes and grasslands with hippos and giraffes to a vast desert, North Africa's sudden geographical transformation 5,000 years ago was one of the planet's most dramatic climate shifts.
The transformation took place nearly simultaneously across the continent's northern half, a new study finds. The results will appear in an upcoming issue of the journal Earth and Planetary Science Letters.

Answer and Explanation:
Archaeologists and historians believed that human beings ceased to be nomads and began to settle in permanent homes after the agricultural revolution. This made human beings realize that it would be better to live in one place and plant their own food, than to hunt. This proved to be very useful for the civilization that was beginning to establish itself, however, in order to practice productive agriculture it was important to establish the division of labor, where each member of the community would be responsible for a certain function that would work in harmony with the other members.
This division of labor promoted rapid agricultural production, allowing the food produced to feed the community and be left over, promoting a surplus of food. This generated the first steps of the trade and a somewhat rudimentary economy, but very efficient to follow the human evolution over the years.
