Fewer slaves and better conditions--The British were typically more lenient on slave laws and there were not as many slaves during the colonial period.
Prior to the American Revolution, slavery was mostly limited to the Southern colonies in particular the Carolinas and Virginia. Slavery under British law was not as strict as it will become and there were often ways to buy freedom. Also slaves were expensive and production was slow. Slavery will increase in the newly formed US after the cotton gin is invented in 1794. This will increase numbers and make the laws more severe leading to more uprisings.
Answer:
Permian - Triassic
Cretaceous - Tertiary
Explanation:
There are two extinction events that influenced greatly the evolution of dinosaurs. The first one was the Permian -Triassic mass extinction, where 95% of the species went extinct. This mass extinction ended the reign of the sinapsids, thus it opened up space for the reptilians, including the ancestors of the dinosaurs. Once the majority of ecological niches were free for taking, the dinosaur ancestors quickly started to evolve and soon after gave rise to the first true dinosaurs. As they were the ones that managed to exploit the environment the fastest, they became the dominant animals on the planet. That lasted until the Cretaceous -Tertiary mass extinction. The dinosaurs died out during this extinction, so their reign was over. Only one branch of the dinosaurs lineage managed to survive, the birds. The birds initially managed to dominate around the world, but with so many empty niches the mammals quickly evolved and managed to out-compete them.
Answer:
Antoine de Cadillac
Explanation:
Antoine de Cadillac was a French explorer who is known as the founder of the American city of Detroit. The word "Detroit" means "strait" in French, and this is the name of the short river that connects Lake St. Clair and Erie (today, this river is exactly on the border between the United States and Canada).
I believe it was the telegraph. This technology was instrumental in spreading news and communicating other information during the civil war.
