Earth Science
Plate Tectonics
• Definition:– The theory that states that pieces of Earth’s
lithosphere are in constant, slow motion, driven by convection currents in the mantle.
Subduction Zones
Subduction Zones
Continental Mountain Ranges
• Definition:– A boundary along which two plates carrying
continental crust push together forming a mountain range.
Continental Mountain Range
Divergent Plate Boundary• Definition:
– A boundary along which two tectonic plates move apart, characterized by either a mid-ocean ridge or a continental rift valley
Convergent Plate Boundaries
• Definition:– A boundary along which two tectonic plates
move towards each other. Characterized either by subduction zone or continental collision.
Convergent Boundaries
Transform Plate Boundary
• Definition:– When two plates are sliding past each other in
opposite directions OR one plates is moving faster than another plate next to it.
