Chapter 17 – Plate Tectonics (aka Putting the Pieces Together!)
BFRB Pages 229-239. In order to study Plate Tectonics, we must first reorganize our layering system for the Earth: Old System – 4 layers Crust (rigid)
Dynamic Earth This unit will cover: layers of the earth, plate tectonics, volcanoes, earthquakes.
Introducing Geology. What is Geology? Geology - the scientific study of Earth. –Physical Geology is the study of: Earth Materials –Minerals –Rocks.
Earth Science Chapter 1 – The Nature of Science. Earth Science OBJECTIVES Differentiate among the four major branches of Earth Science. Contrast the four.
Ch. 4.2 The Theory of Plate Tectonics. The theory of plate tectonics explains the what, how and why of continental movement. Two types of earth’s crust:

Essential Questions How does the movement of Earth’s tectonic plates result in many geologic features? What are the three types of plate boundaries and.
17.1 Drifting Continents. Early Observations In the late 1500s, mapmakers noticed the apparent “fit” of the continents on either side of the Atlantic.

Physical Science Review: Earth Science. Earth’s Interior The layers of the Earth are the crust, the mantle, and the core. Crust- top layer, made up of.
What we know… Wegener collected evidence and proposed the theory of Continental Drift. Hess found the “mechanism” to support the idea with his theory.
