WHO ORIGINATED THE THEARY OF PANGAEA?

In 1912, Alfred Wegener noticed how the continents fit together like a puzzle. He then figured that all continents were compressed into a single protocontinent which he called Pangaea, which means “All lands”.

He believed that Pangaea was intact until about 300 million years ago.

What Earth time period did Pangaea Exist?

Pangaea existed in the Carboniferous time period. The Carboniferous Time Period was a time of low sea level and mountain building. Carboniferous Time Period Carboniferous Time Period.

Alfred Wegener

Something that could have helped Alfred Wegener was that he was also a paleontologist. A paleontologist is a scientist that studies prehistoric life, including organisms' evolution and interactions with each other and their environments.

This related to his discovery because Paleontology studies prehistoric life, and since Pangaea was prehistoric, it was easier to find out for him than just a geologist.

Convergent Boundary

A Convergent Boundary, also known as a destructive plate boundary is an actively deforming region where two or more tectonic plates or fragments of lithosphere move toward one another and collide.

One hazard that has happened are earthquakes, mud/landslides, and trenches, and volcanoes.

One example of a Convergent Boundary is the Himalayas.

Divergent Boundary

A Divergent Boundary or divergent plate boundary is a linear feature that exists between two tectonic plates that are moving away from each other.

Some Example of a Divergent Boundary is The Red Sea Rift, Mid-Atlantic Ridge, and The Gakkel Ridge.

Transform Boundary

A transform Boundary is a fault which runs along the boundary of a tectonic plate.

A few examples if a Transform Boundary are North America’s Queen Charlotte fault, Pakistan’s Chaman fault, and New Zealand’s alpine fault.

What plate do we live on?

We live on the North American Plate, but some of California and Alaska sit on the Pacific Plate.

The North American plate has had many shakes by earthquakes, but not around Ohio. The quakes are mostly around the top of the San Andreas Fault.

Potential Problems thatcould happen in the distant future are the plates moving to adifferent location.
