Discovering Plate Tectonics: Major Plate Boundaries Hook 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

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.
