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 major cause for the expansion of slavery in the south was due  to the invention of the cotton gin by Eli Whitney.Harvesting  cotton by hand was inefficient and it seeme â¦ d that the cotton  growing industry was fading away, and thus the demand for slavery  as well.lantations required large numbers of workers, so wealthy landowners bought lots of slaves. In the northe â¦ rn colonies, the geography and climate weren't favorable for large-scale farming. Up north, there wasn't as much good farmland, and the growing season was shorter.
