When looking at a map, the continents look stationary and stalwart. The theory of plate tectonics however, shows our planet is dynamic and ever-changing.

Geology, according to geology.com, is the study of the Earth, the materials that make it, the structure of these materials, and the processes that act upon them.
A geologist may study floods, earthquakes, volcanic eruptions, and rock layers of the Earth.
What is underlying all of these fields of study though, is the dynamics of a global system known as plate tectonics.
One of the most famous advocates for the theory of plate tectonics was German scientist, geophysicist and meterologist named Alfred Wagner. (Wikipedia)
He hypothesized that the continents of the Earth were slowly moving about the globe but could not come up with a defined mechanism of how it worked.
Wagner died in 1930 and his hypothesis of what he called “continental drift” seemed to die with him.
