Pangea was a huge super continent more than 200 million years ago that combined all the continents we have today into one huge continent. The theory of Pangea and continental drift was originated by Alfred Wegener in 1915. The idea of Pangea was not accepted by scientists until the 1960’s. Alfred Wegener not only was a geologist, he studied weather as well and this helped him produce his theory. http://www.enchantedlearning.com/subj ects/astronomy/planets/earth/Continent s.shtml http://www.ucmp.berkeley.edu/history/wegener.html

A convergent boundary is when 2 plates meet and one plate slides under the other which sometimes creates volcanic eruptions, earthquakes, and crustal deformation which creates land and mudslides. One example of a convergent boundary is the Washington-Oregon coastline. http://geology.com/nsta/convergent- plate-boundaries.shtml

A Divergent Boundary is when 2 plates meet and push upward to form a ridge. Some effects of divergent boundaries are; mild earthquake activity, mountains, and volcanic fissure eruptions. One example of a divergent boundary is the Mid-Atlantic ridge. http://geology.com/nsta/convergent- plate-boundaries.shtml
5
Transform Boundaries are where 2 plates slide against each other which creates transform faults. These faults create earthquakes repetitively. A famous example of a transform fault is the San Andreas fault which is between the Pacific, and N.A. plates http://geology.com/nsta/transform-plate- boundaries.shtml

We live on the North American plate with the Eurasian plate to the East, the Pacific plate to the West, and the South American plate to the South. Ohio does not usually have disasters relating to the tectonic plates, however the West coast is always in danger because of the San Andreas fault.
7
In the very distant future Ohio may be in some danger because the South American plate will have moved up and a fault will be right to the South of Southern Ohio.
