Plates by Katie Lanoue and Jeanine Brown The Formation of a Theory In 1915 a German scientist named Alfred Wegner came up with the theory of continental drift His hypothesis was that all the continents were once connected to form a supercontinent called Pangaea. Structure of the Earth. The Earth is made up of 3 main layers:. Core. Mantle. Crust. Inner core. Outer core. Mantle. Crust. The Crust. This is where we live!. The Earth’s crust is made of:.

Today, you might be laughed out of a geology course for questioning whether continents move through geologic time. But 75 years ago, only skeptics believed that continents could take a hike. Talk about conventional . The Most Amazingly Radical Tectonic Area Project . M.A.R.T.A.. Skype Session . With Ranger Mike from Yellowstone National Park kicked off the project.. He spoke to students about how important what goes on inside the Earth is to Yellowstone.. 4 Layers of the earth. 7 main plates of the earth. 3 main plate boundaries. 2 types of crust. 3 main features of plate tectonics (F.E.E.D). 3 main theorists and theories. Human interaction. Structure of the Earth. Why do people live in tectonic areas and how are the possible effects being managed?. Why do people live in tectonic areas?. In pairs discuss: . Which area of the world has the highest number of people potentially affected by tectonic activity?. Volcanism is mostly focused at plate margins. Pacific Ring of Fire. This map shows the margins of the Pacific tectonic plate and surrounding region. The red dots show the location of active volcanism. Notice how the majority of the volcanism is focused in lines along the plate boundaries? For this region is the area known as the “Pacific Ring of Fire”..

For example the San Andreas Fault, a conservative plate margin. Furthermore, earthquakes also occur on the constructive plate boundaries of the Mid- Atlantic Ridge, although these are not as severe.
