Our Changing Earth. What is a Theory? In science, its almost the same as a fact Must be some sort of evidence to support a theory Even with evidence there.
Plate Tectonics 6.E.2.2 Explain how crustal plates and ocean basins are formed, move and interact using earthquakes, heat flow and volcanoes to reflect.

Theory of Plate Tectonics Plate Tectonics Plate Boundaries Causes of Plate Tectonics.
Continents change position over time. Alfred Wegener Evidence Hypothesis – continental drift Earths continents were once joined Super Continent called.
The Theory of Plate Tectonics. The lithosphere is divided into separate sections called plates. The plates carry continents and ocean crust or both.
Topic: Earth’s Features Essential Question: What crustal features are created by the movement of Earth’s plates?
Earths Crust Convection currents Continental drift – idea that continents have moved slowly to their current positions due to convection currents in.
Birth of a Theory Continental Drift and Plate Tectonics.
Continental Drift Chapter 10 Section 1. Continental Puzzle Do the continents fit together perfectly? What continents fit the best? What other information.
Plate Tectonics. Brief Structure of the Earth Divided into layers: –Core, mantle, crust.
UNIT 4 THE RESTLESS EARTH PART I LESSONS 1, 2, & 3 The Big Idea: The movement of tectonic plates accounts for important features of Earth’s surface and.

Ch 7: Plate Tectonics A work in progress …. Animation of Continental Drift pangea moving Pangea w/ labels PANGAEA: – Name of a supercontinent. – All continents.
Warm Up 11/ What hypothesis states that the continents were once joined to form a single supercontinent? a. continental driftc. plate tectonics.
Plate Tectonics What evidence do scientists have to support the fact that the Earths crust is continuously moving?
Plate Tectonics Lynn Hahn. Tectonic Plate Theory Theory that explains the movement of continents across the globe. It explains why some earthquakes occur.
Chapter 8: Plate TectonicsChapter 8: Plate Tectonics 8.1: Earth has several layers 8.2: Continents change position over time 8.3: Plates move apart 8.4:
The Theory of Plate Tectonics. Plate Tectonics Plate tectonics is the theory that explains why and how continents move. By the 1960s evidence supported.
Geology - is the study of rocks and materials that make up Earth and the processes that shape it.
Continental Drift Chapter 10, Section 1. Continental Drift Theory that states that all continents slowly move through time. –Suggests that all continents.
Plate Tectonics. The Earth's surface is made up of a series of large plates (like pieces of a giant jigsaw puzzle). These plates are in constant motion.
