THE TECTONIC CYCLE
• Lithosphere is comprised of several plates
floating on denser material
• Plates move slowly relative to each other – plate
tectonics.
• Divergent plate boundaries occur at spreading
ocean ridges.
• Convergent plate boundaries occur when plates
collide.
• Plate movements change the
location of continents and alter
atmospheric and ocean circulation
patterns.
• Plate boundaries are geologically
active, producing volcanoes and
earthquakes.
