Fold and Glue into Notebook Plate Tectonics Notes Plate tectonics: The theory that explains how large pieces of the Earth’s outermost layer, called tectonic plates, move and change shape. Plate boundary: Place where two tectonic plates ______________ (Like the seams on a puzzle that is put together) a. All tectonic plates ________________ boundaries with other tectonic plates. b. There are 3 types of plate boundaries. c. The type of boundary depends on how the two plates ________________________. Draw the arrows for each type:

1. Convergent Boundaries: 3 types depending on the crusts that meet Collision of two lithospheric plates A. Continental-Continental Collision When continental plates ____________________, they buckle and thicken, which pushes the continental crust upward. Result: _____________________________________ B. Continental-Oceanic Collision When a plate with oceanic crust collides with a plate with continental crust, the __________________oceanic crust sinks (________________) into the ________________________________. C. Oceanic-Oceanic Collision When two tectonic plates with oceanic lithosphere collide, __________ of the plates with oceanic lithosphere is subducted, or ________________, under the other plate. Result: Trenches, ___________________________________, or island formation 2. Divergent Boundary The boundary between two tectonic plates that are moving ___________________ from each other. Oceanic Separation Result:________________________ B. Continental Separation Result:_____________________________ 3. Transform Boundary When plates are sliding past each other __________________. A. Continental or Oceanic Plates Slide As two plates ______________________ past each other, their irregular edges ___________________ and jerk. Result: _________________________________________ Two plates _____________ from each other. As they move apart, ________ may rise to fill the gap.
