Earth Science Lecture Chapter 4 - Plate Tectonics

Natural disasters and other geologic changes to our planet’s topography can be traced to the same source, and are the growing pains of a still-forming Earth. The consequences of a changing planet have their origins in the drifting motion of the Earth’s crust. Earth’s geologic story begins with the Theory of Continental Drift and later described in Plate Tectonics. Earth’s internal structure is investigated for the source of the driving energy behind plate tectonics and presented with numerous examples of the consequences of plate movement, including Earthquakes, Volcanoes & Mountains.
