Presentation Transcript

  1. 19 9/9 Plate tectonics – lithosphere is broken into plates that move on convection currents of the asthenosphere • Theory • Move away • Collide • Grind

  2. 20 9/9 Convection – heat transfer causing heat to rise • Liquids, gas • Mantle • Rock cycle

  3. 21 9/10 Divergent Boundary - Areas between two plates that are moving apart. • Seafloor spreading • Mid-ocean ridges • Rift valleys

  4. 22 9/10 Seafloor spreading - The process of new land being formed as magma reaches the surface at oceanic divergent boundaries • Lava becomes land

  5. 23 9/11 Convergent boundary – areas between 2 plates that are colliding into each other • Mountains • Volcanoes • Subduction zone

  6. 24 9/11 Subduction - The area where the oceanic crust is pushed below the continental crust • Crust melts • Crust rises and becomes volcanoes

  7. 25 9/12 Folded mountains – rocks in the lithosphere bend slowly to produce mountains Stress Compression Mt. Everest

  8. 26 9/12 Transform Boundary -Areas between two plates that are moving and grinding past each other. • Large earthquakes • Strike-slip • Shearing

  9. 27 9/13 Displace – to move something from its usual place • Stress • Pressure

  10. 28 9/13 Trial – set of repeated data to test one variable • Experiment • Data table • Procedure
