  1. Lithosphere- made up of the crust and very top of the mantle- also known as a tectonic plate Asthenosphere- hotter, softer layer of rock on which the lithosphere rests. Ocean crust is ______ Continent crust is ____ To understand how plates move, here are more details about the Earth’s crust:

  2. Label your drawing

  3. Continental Drift- Alfred Wegener said that the continents used to be all together in one large landmass called: Pangaea Evidence: Similar rocks and Similar fossils on different continents Can you create Pangaea?

  4. The Seafloor is spreading apartMid-Atlantic ridge- underwater mountain range formed by convection currents in the asthenosphere

  5. 1. Divergent Boundary a. Ocean-ocean pulling apart b. Forms underwater mountain range c. Mid- Atlantic Ridge

  6. 1. Divergent boundary a. Continent- continent pulling apart b. Forms a rift valley c. Africa- Great Rift Valley

  7. 2.Convergent- a. ocean-ocean coming together b. Forms a trench and subduction zone Forms volcanic islands c. Japan

  8. 2.Convergent Boundarymoving together Continent- continent coming together b. Forms mountains c. Himalayas- Mt. Everest

  9. 2. Convergent Boundary a. Ocean- continent b. Forms a trench and volcanic mountains c. Washington State and Andes mountains in South America

  10. 3.Transform boundarysliding past each other b. Forms earthquakes c. San Andreas Fault in California

  11. Identify each drawing as divergent, convergent or transform
