  • T/F New lithosphere is always forming on top of large mountains
    False
  • What is MOST likely to occur at a transform plate boundary?
    earthquakes.
  • T/F Geological processes form rock
    True
  • T/F Geological processes form rock
    True
  • T/F Rocks can break down into sediments
    True
  • Continental drift is the idea that__________.
    the continents were once joined together to form a large landmass, have moved over time.
  • The three types of rocks are classified by _____.
    how they are formed
  • T/F Old lithosphere is destroyed and new lithosphere is formed over time
    True
  • Most earthquakes happen more frequently at
    plate boundaries
  • New lithosphere is MOSTLY created at what type of plate boundary?
    divergent
  • This describes the process in which one rock type becomes another rock type
    rock cycle
  • Lithosphere plates move towards each other at which type of plate boundary?
    convergent plate boundary
  • T/F Subduction provides enough heat and pressure to change a sedimentary rock into a metamorphic rock
    True
  • Explain how sediments become sedimentary rock.
    Sediments are pressed and glued together over long periods of geological time.
  • T/F Earth's lithosphere moves around but is never destroyed
    False
  • What provides evidence for the theory of plate tectonics?
    fossils, rock layers, and gps measurements that show the plates are moving
  • The process in which one plate is being pulled under another plate is called _____.
    subduction
  • T/F Rocks can't change from sedimentary to metamorphic
    False
  • Plate tectonics refers to the theory that _________.
    Earth's surface is made up of lithospheric plates that have moved over time.
  • Where do most metamorphic rocks form?
    Deep underground
  • Plates move away from each other at______.
    divergent boundaries
  • What is convection?
    The transfer of thermal energy by the movement of matter of different temperatures.
