PLATE TECTONICS

PLATE TECTONICS. Nafisa Skeie. What is plate tectonics?. The build up of plates…?. Or is it the build up of food onto a plate…?. Geographically…. Plate: Large, rigid slab of Earth’s solid rock. + Tectonics: From the Greek root “to build”. Plate Tectonics =

Topics of Discussion. Layers of EarthContinental DriftSeafloor Spreading Plate TectonicsMountains. Layers of Earth. Clues to Earth's Interior. Although the best way to find out what's inside Earth might be to dig a tunnel to its center, that isn't possible.Geologists must use indirect observations to gather clues about what Earth's interior is made of and how it is structured.This indirect evidence includes information learned by studying earthquakes and rocks that are exposed at Earth's s30028

CHAPTER. Plate Tectonics. 18. Three factors cause the movement of Earth’s tectonic plates: mantle convection, ridge push, and slab pull. Forces at plate boundaries produce landscape features such as mountains, trenches, and island arches. CHAPTER. Plate Tectonics. 18.
