The Presidential Election map showed that The deep political divisions in the United States created a fractured electorate.
<h3 /><h3>What was shown by the 1860 election map?</h3>
The Democrats supported slavery in 1860 which was why they won the votes in the South. This was because the South supported slavery as their main economic industries such as cash crops, relied on enslaved labor.
The Republicans led by Abraham Lincoln were against slavery and were able to win in the North. This was because the North were against slavery for a mix of reasons with one of them being that they didn't like how cheap labor was in the South.
This showed that the political divisions in the U.S. led to a fractured electorate.

Explanation:
Pangea was a super-continent on the earth which formed about 330 million years ago during the Paleozoic and began breaking up during the early Mesozoic, about 175 million years ago.
Most of the present day continents formed as a result of the separation of the Pangea in the early Mesozoic.
The first scientist to propose the existence of this super-continent was Alfred Wegener in 1912. He suggested the continental drift hypothesis to explain the separation of the land masses.
Today, the theory has been revised to the theory of plate tectonics which provides a better mechanism to understand the drifting of the continents.
Here are some of the evidences to support the existence of Pangea;
- Using fossil evidences: Mesosaurus, a reptile animal that lived during the Permian, was found in both South America and Southern Africa. Since this animal could not swim nor fly, only a jointed landmass could have made them present in both continents.
- Similar rock lithologies at the edges of continents: rock formations at the Western edge of Africa and South - Eastern part of Brazil matches with one another and have been believed to be once joined together.
- Climatic clues such as glacial tills that are confined to temperate and polar regions have been found in tropical regions.
- Wegener fitted the present day continent into a giant supercontinent and this provided a visual support for his claim.
- Evidences from sea floor spreading revealing magnetic reversals at divergent margins suggests the prevalence of plate tectonics i.e moving plates on earth.
This among many other evidences underscores the existence of a supercontinent called Pangea.
The two largest metropolitan in Canada are Toronto and
Montreal. Toronto lies in the province of Ontario and Montreal lies in the
province of Quebec. These are huge metropolitan cities having great amount of
population. Canada is a country that has got a huge number of immigrants coming
in to the country. This process has been going on for the last 30 years. This
did have a direct impact on the culture of the society. Many metropolitans like
Toronto and Montreal have seen the highest amount of people coming in.
