TRANSFORM BOUNDARIES: Lithosphere is not created or destroyed Divergent boundary Transform boundary Volcano Depth rench and convergent Volcano Seafloor Oceanic crus spreading basaltic Continental crust boundary (granitic) spreading Lithospheric mantle Lithospheric mantle Mantle (peridotite Divergent DIVERGENT PLATE BOUNDARIES: Melting Lithosphere mantle asthenosphere is created Shallow focus earthquakes O-69 km) (ocean ridges and Intermediate focus earthquakes 70-299 km) continental rifts) Deep focus earthquakes 800-700 km) 0 a or lava (molten rock) Ocean-ocean Ocean-continent Continent-continent CONVERGENT PLATE BOUNDARIES: Lithosphere is destroyed FIGURE 2.2 Three kinds of plate boundaries: divergent, convergent and transform boundaries. White arrowsindicate motions of the lithospheric plates.Half arrows on the transform fault boundary indicate relative motion of the two blocks on either side of the fault.The focus of an earthquake isthe exact location where an earthquake occurred (shallow, intermediate, or deep. Water in subducted plates can lower the melting point of rock just above them at intermediate depths and lead to formationofvolcanoes. 42 LABORATORY
