2. What is Pangaea?
Pangaea was a theory that was created by Alfred Wegener, that all of the continents were once combined into a super continent which he called, “Pangaea”. Originally scientists dismissed his theory because he couldn’t explain how the continents would move, or drift, from their original location.

3. Pangaea
The name “Pangaea” literally means “entire Earth” from the Greek roots pan- meaning entire and Gaea- meaning Earth. It is believed that Pangaea was intact until the late Carboniferous period which was about 300 million years ago. Before Wegener's idea of Pangaea the only y other theory of continental placement is that the continents never moved, but throughout time, land bridges have formed and disappered, Allowing animals to move across to other continents.

4. Alfred Wegener
Alfred Wegener was born on November 1, 1880 in Berlin. He earned his PhD In astronomy at the University of Berlin in During his life he made several contributions to meteorology. Another major thing that he had done during his life was write a book that eventually became a standard in germany. He died a few days after celebrating his 50th birthday.

5. Arthur Holmes
Arthur Holmes was a man that elaborated and did more reasearch on one of Alfred Wegeners many hypothieses. This hyptothesis was that the matntel undergoes thermal convection. With thermal convection, when something heats up towards the bottom of something it rises until it cools down and sinks until it is heated up again. A great example of this is a lava lamp. These ideas related to wegeners findings because that was exactly what he was trying to prove to show that his “super continent” idea was in fact, correct.

6. Convergent boundaries
A convergent boundary is when two plates ,that are going in opposite directions meet and one plate is forced under the other one. A convergent boundary is usually charaterized by hazardous characteristics such as eartquakes, volacnoes, and sometimes even mountains or deep ocean trenches. Eartquakes can also cause tsunamis and landslides.

7. Real life examples
A real life example of a convergent boundary involves the Juan de Fuca plate and the North America plate. The Juan de Fuca plate is slowly moving underneath the North America plate.

8. Divergent boundaries
A divergent boundary is when two plates that are next to each other slowly pull apart. The pulling apart of these plaes causes “”sea-floor spreading”. Some of the hazads involved with these boundaries is that there are earthwuakes, and volcanoes bcasue oof the magma that is rising upwarfd.

9. More real life examples
A real life example of a divergent boundary involves the African plate and the Arabian plate. Saudi Arabia (located on the Arabian plate) is slowly moving away from Africa (located on the Africa plate). Between the two plates is the Red Sea which has formed since the two plates have moved farther and farther away.

10. Transform boundary
A transform boundary is when one plate slides horizantily past another one. One of the bst known examples s the San Andres fault. It is the border between the North American plates and the Pacific plates. Some of the most common hazards of a transform boudary are earthquakes. Tsunamies and landslides can also be caused by eartquakes.

11. Real world connections
If you live in the US then you probably know that we live on the North America plate. Anther thing you probably know is that there are many plates surounding us. Some of the are Juan de Fuca plate to the west, the Pacific plate to the southwest, the Cocos and Carribean plate to the south, the South America plate to the southeast, the African and Eurasian plate to the east, and finally the Antarctic plate to the north.

12. More real world connections
Is the united states in any hazards from plate tectonics? Actually the only place that is in any danger from plate tectonics is probably Califonia because of San Andres fault. San Andres fault is a very large transform boundary between the Pacific plate and the North America plate.

13. The Future
There are a lot of great things in store for the future of this world. Maybe someone will invent a car that runs of water, maybe someone will invent a cure for cancer. No one knows for sure. Although one thing that I do predict is that all of the conitinents will be joined again and ultimately, create another Pangaea. If this were to happen it wouldn’t happen for a very long time, it would take millons of years for the continents to rejoin.
