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.
Slavery was known in civilizations as old as Sumer, as well as almost every other ancient civilization. The ByzantineâOttoman wars and the Ottoman wars in Europe resulted in the taking of large numbers of Christian slaves. Slavery became common within the British Isles during the Middle Ages. Britain played a prominent role in the Atlantic slave trade, especially after 1600. Slavery was a legal institution in all of the 13 American colonies and Canada (acquired by Britain in 1763).
