PPT-Plate Tectonics

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. Liz LaRosa for use with my 5. th. Grade Science Class . http://www.middleschoolscience.com. 2009 . Earth’s Layers. The Earth's rocky outer crust solidified billions of years ago, soon after the Earth formed. . The word tectonics derives from the Greek tektonikos, meaning "pertaining to construction." Robert T.

Major questions on initiation of plate tectonics. Evolution of the Earth. Cracks in the Earth’s Crust. The . crust. , when it is solid, acts as a . heat insulator. for the hot interior of the Earth.. The molten material in the mantle, . magma. , below the crust builds up tremendous heat and pressure. . One moves oil, while the other builds mountains. Which can do more work?. Supertanker . Tectonic Plate . Mass - 2 x 10. 8. kg. Velocity - 8 m/s. Mass - 3 x 10. 20. kg. Velocity - 1 x 10. -9. m/s. Zachary Gallegos. University of New Mexico / Mars One. Mars Orbiter Laser Altimeter Map. Plate Tectonics. Lithospheric plates sliding on the asthenosphere, above the mantle. Exists on Earth. Theory proposed in the early 1900’s. Composition of the Earth: . Layers of the Earth: . Crust: . 5-100km thick. . Oceanic crust: thin and more dense, mostly basalt . Continental crust: thicker and less dense, made up of more granite than oceanic crust . 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”.. 6. th. year Geography. Learning Outcome. Revise Core Book. Chapters 1 – 3. Plate Tectonics. Earthquakes. Volcanoes.
