WHAT IF PANGAEA NEVER BROKE APART??? Like this…

[object Object],[object Object],[object Object]

Dinosaurs went extinct from a 5-mile wide asteroid that hit Mexico, which caused dirt and debris to rise into the air and block out the sun. As you can see, if Pangaea didn’t separate, it would have hit the water and some dinosaurs would still be alive. This is where the asteroid hit during the time of the dinosaurs. This is where the asteroid would’ve hit if Pangaea was still a Super-Continent This is because…

Pangaea drifted apart because the tectonic plates under the land moved apart due to convection in the magma. Just to make things simpler, the magma in Earth’s core moves, bringing the land above with it. ,[object Object],Hot spots are formed when magma pushes its way through the middle of a tectonic plate. They create shield volcanoes which are one of the least deadliest volcanoes in the world. They have Basilic lava which is just liquidly lava. Examples of a shield volcanoes are the ones in Hawaii. Also, we wouldn’t have any volcano archipelagos like Hawaii. Hawaii was formed by an undersea volcano. The lava from the volcano created the land of Hawaii. The island is a archipelago because while the volcano was in the middle of creating an island, it shifted away from the island because the tectonic plate below it was moving. It then created another island. Then the island got cut off again because the volcano moved away. The volcano created more and more islands this way which then became an archipelago. But there would have been just one big volcano if it hadn’t moved from tectonic plates.

Here is an animation (it’s a bit crappy though)

[object Object],Without tectonic plates though, earthquakes will never exist. Other disasters caused by earthquakes such as tsunamis and land slides will never happen as well. Without that much natural disasters, the population of people would probably be larger. (If we ignore the fact that the human race would've never existed since nothing happened to the dinosaurs.)
