APES UNIT 4 REVIEW EXAM QUESTIONS
AND ANSWERS
Earth's spheres - -lithosphere, atmosphere, hydrosphere, biosphere
-Earth's core levels - -- inner core; solid
- outer core; liquid
- mantle
- asthenosphere
- lithosphere (earth's surface)
-Earth's surface composed of... - -continental crust and oceanic crust
-Which is denser, oceanic crust or continental crust? - -oceanic
-Plate tectonics theory - -a model of movement of Earth's crust
-Convection currents exist in cells in the... - -lower mantle and the upper mantle
(asthenosphere)
-Wilson Cycle (1960's) Theory - -Wilson proposed that land masses repeatedly join to
form a supercontinent, and then split apart
-Why are fossil remains significant to proving continental drift? - -fossil remains provide
evidence from continent to continent that they were once connected
-divergent boundary - -spreading apart
constructive (oceanic lithosphere created)
forms ridge/rift
volcanic activity (sea floor spreading)
-Convergent boundary - -subduction destructive (oceanic lithosphere destroyed)
forms trenches
volcanic activity
-transform boundary - -lateral sliding
neutral (doesn't create or destroy)
doesn't form anything
NO volcanic activity (earthquakes)
-define faults - -fractures in the earth's crust caused by stress
-Types of faults - -Type 1: normal fault
Type 2: reverse fault
