PPT-Plate Boundaries Plate Boundaries

Why do we care about plate boundaries Plate Boundaries Volcanoes and earthquakes most often occur where tectonic plates come together At plate boundaries many other geologic features such as mountains and rift valleys can also occur. Where are the Earth’s tectonic plates and their boundaries?. What happens at plate boundaries?. How do Earth scientists classify plate boundaries?. Part 1.. Identify the patterns of your area of expertise – volcanology, seismology, geography, geochronology - AT PLATE BOUNDARIES. Imagine the Earth as a hardboiled egg…………………….. The thin brittle shell is the crust that humans live on.. The thick jelly like white is the deep hot magma beneath the surface.. The yellow yolk is the core of the earth.. 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:. Continental Crust. Chapter 12.2 BC Science 10. A Cross-Section of Earth. The Layers of Earth. Earth is over 1200 km thick and has four distinct layers:. Crust. – outer solid rock layer (granite on land, basalt in oceans). Construcive. (Divergent). Plate. Movements. Geological Process Associated. Landforms. Example. Two. plates of the oceanic crust moving apart from each other. Two plates of continental crust moving apart from each other. Standard . S6E5.d . Recognize that lithospheric plates constantly move and cause major geological events on the earth’s surface.. What You Will Learn. Describe the three types of tectonic plate boundaries. . 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”.. The Great California . ShakeOut. . Divergent . Boundaries:. Two plates pull . apart. Convergent Boundaries:. Two plates push together. Transform Boundaries:. Two plates slide horizontally against one another. 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”.. Lesson. . Objectives:. To understand what occurs at different plate boundaries.. Success Criteria:. Create an annotated diagram of each plate boundary.. Plate 1. Plate 2. Continental crust. THE WORLD’S MAIN PLATE BOUNDARIES. CONTINENTAL DRIFT THEORY. ALFRED WEGENER . proposed all continents . . originally formed from one landmass . . (PANGEA). EVIDENCE OF CONTINENTAL DRIFT:. . 1. Fossilized tropical plants in Greenland. Divergent. Convergent. Transform. Three types of plate boundary. Spreading ridges. As plates move apart new material is erupted to fill the gap. Divergent Boundaries. Iceland has a divergent plate boundary running through its middle. 1. 2. Oceanic crust. 1-Convection currents pull plates apart. . 3-As the plates move apart, magma from the mantle rises to fill the gaps and forms new oceanic crust.. 4-A mid-ocean ridge is formed by the new crust. .
