2. Section 1: Pangean History
Alfred Wegener developed a theory of continental drift and all the continents being together one at one time, in 1915.
Originally, this theory was not accepted by scientists, because of lack of solid evidence.
Pangaea means “all lands” in Greek, and was together in the Paleozoic and Mesozoic eras about 250 million years ago
There was a theory of sunken land bridges, connecting the continents, during Wegeners time.
Alfred Wegener was an accomplished graduate in geology and meteorology. This graduate in these sciences would have had a relation with the weather patterns of Pangaea 250 million years ago.
Arthur Holmes’ ideas later assisted Wegeners theory by proposing the idea of convection cells under the earths mantle.

3. Section 2: Convergent Boundaries
A convergent boundary is a Destructive area of where two or more tectonic plates collide and cause earthquakes, volcanoes, mountains, and trenches.
Examples of convergent boundaries are the collision between the Eurasian plate and the Indian plate that forms the himilayas, or the Mariana Trench. Also the collision of the Nazca Plate beneath the South American Plate that forms the andes Mountains.
Trench, Earthquake, Volcanoe, Mountain, convergent boundary.

4. Section 3: Divergent Boundaries
A divergent boundary is when two plates move apart from each other and the space that this creates is filled with new crust material from molten Magma that forms below.
Divergent boundaries can cause Rifts, Rises, and Ridges. These are divisions in the crust that are different heights than before the plates seperated.
One example of a divergent boundary is The East African Ridge.

5. Section 4:Transform Boundaries
A transform boundary, is a Fault which runs along the boundary of a Tectonic Plate. This moving of plates usually builds up massive amounts of energy, cuasing earthquakes,and Landslides or mudslides.
An example of a transform boundary would be the Queen charlotte fault.

6. Section 5: Real World Connections
We live on the North American Plate.
The North American Plate is bordered by the Carribean, Cocos, Pacific and Juan de Pucos plates.
We are not in any serious danger of Hazards in Ohio, but in California, a fault line runs right next to the coast and Earthquakes have happened there many times.
I can only predict Earthquakes, and Mud and landslides in the California area, because of the Transform boundaries in that region. But also, Volcanoes possibly making bigger hawaiian islands, and the Aleutian islands being destroyed by earthquakes.
