<p> Date ______-N Plate Tectonics – Guided Notes</p><p>Plate Tectonics:</p><p>1. According to the theory of ______, Earth’s crust and part of the upper mantle, known as the ______, are broken into sections. </p><p>2. These sections, called______, move on a plasticlike layer of the mantle, known as the ______.</p><p>Plate Boundaries:</p><p>1. Plates can ______, or ______or ______or slide alongside one another.</p><p>3 Types of Plate Boundaries:</p><p>A. Plates Moving Apart –</p><p>1. ______: The boundary between two plates that are moving apart. </p><p>2. ______: a. New sea floor being made, b. Underwater Volcanic mtns</p><p>Other features found at the Mid-Ocean Ridge: • • •</p><p>3. Another type of Divergent boundary is the: ______. - Features found at a Rift Valley • ______• ______created by a ______force</p><p>B. Plates Moving Together</p><p>1. ______: occurs where two plates move together. (collide causing a collision area – like a head on crash of two cars) </p><p>2. Where Two Continental Plates Collide They form:  ______(material being scraped up and pushed together)  ______</p><p>3. When an ______plate converges with a less dense ______plate, the denser oceanic plate sinks under the continental plate.</p><p>4. ______: The area where an oceanic plate subducts, or goes down, into the mantle. Features found at a subduction zone….. • ______• ______• ______• ______5. ______type of convergent boundary created where one plate bends and sinks beneath the other. • Old Sea Floor being destroyed </p><p>6. The newly formed magma is forced upward along these plate boundaries, forming ______. </p><p>Where Plates Collide</p><p>1. A subduction zone also can form where two ______plates converge. </p><p>• In this case, the colder, older, ______oceanic plate bends and sinks down into the mantle. </p><p>C. Where Plates Slide Past Each Other</p><p>1. ______: Occur where two plates slide past one another. • They move in opposite directions or in the same direction at different rates. </p><p>Features: ______The ______is part of a transform plate boundary. It has been the site of many earthquakes. </p><p>Causes of Plate Tectonics</p><p>______: The cycle of heating, rising, cooling, and sinking. • This process occurs in the ______, it is thought to be the force behind plate tectonics. </p>
