Tectonic Plate Boundaries Flashcards
Constructive Plate Boundary
Tectonic plates drift apart
Magma rises, cools, spreads creating new crust
Mostly at bottom of sea
Volcanos creatsd, weaker earthquakes
Destructive plate boundary
Tectonic plates carried towards each other
Oceanic plate subducts under continental plate due to being more dense
Rocks grinding and getting stuck creates energy and when plates jolt and are released , huge amounts of energy get released causing earthquakes,
Oceanic plate causes co2 and other gasses to rise under the continental plate building up pressure leading on to a volcano
Collision Boundary
Both plates continental, similar density’s
Drift towards each other and crash, crumbling upwards creating fold mountains, Earthquakes caused
Conservative Boundary
Crustal plates slide past each other, grinding, getting caught, building up energy, when they release from each other and jolt, huge amounts of energy released, causing earthquake
