Answer:
Before mountain building occurred, the area was underwater.
Explanation:
Through excavation, fossils that are of marine animals are often found high on mountain ranges. This seems weird from today's perspective, as marine animals can only be found in ocean waters, and there is no way they can travel on land and upon the mountains. Earth has changed a lot throughout history though, so such occurances are actually not that weird.
The mountains in Pennsylvania are such a place, with an abundance of marine fossils. When we look at the geological past of what is now Pennsylvania we can easily see why this is the case. The whole area was actually underwater for millions of years. This was the case before mountain building occurred here when part of the ocean floor raised high above the surface of the water and created land. As the crust was going up, the fossils on it went up as well.

Explanation:
Mongolia has very little arable land, which means historically they have not been able to grow enough crops to support a large population. Until the 20th century Mongolians were largely a herding people, and that just doesn't support dense populations.

Population would go down drastically and there would be no next generation x
Answer:
According to Google, Nunavut has the lowest population density in Canada. This might occur because it's made up of islands and the area is a tundra so it's very cold and doesn't support agriculture. The islands are also accessible only by plane or boat so it's hard for people to move to the area.
