Neptune has six known rings. Voyager 2's observations confirmed that these unusual rings are not uniform but have four thick regions (clumps of dust) called arcs. The rings are thought to be relatively young and short-lived. Neptune has 13 known moons, six of which were discovered by Voyager 2.
Why was slavery introduced to the English colonies? Slavery was introduced to the English colonies because people were  in need of labor to develop the lands. There was a lot of work to  be done, and there was little money toâ¦ pay for labor. The human  trade was a solution to the issue. Although, this was not a humane  practice.
The history of slavery in Texas began slowly, as the Spanish did not rely on it for labor during their years of control. The use of slavery expanded in the mid-nineteenth century as British-American settlers from the Southeastern United States crossed the Mississippi River and brought slaves with them.he governors feared the growth in the Anglo-American population in Texas, and for various reasons, by the early 19th century, they and their superiors in Mexico City disapproved of expanding slavery.
