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 changes did not stop forced labor in the Spanish colonies on the mainland, which took on a new guise under the repartimiento. In addition, in the West Indies, the colonists needed a new source of labor and began to import African slaves, joining the transatlantic slave trade.he Spanish colonies in the Caribbean were among the last to abolish slavery. While the British colonies abolished slavery completely by 1834, Spain abolished slavery in Puerto Rico in 1873 and in Cuba in 1866. On the mainland of Central and South America, Spain ended African slavery in the eighteenth century.
