Term	Definition
Subduction	When denser plates sink under less dense plates
Lava	Magma that's exited the earth's crust
Mafic	Igneous rocks with lots of magnesium and iron
Felsic	Igneous rocks with many elements that form feldspar and etc,
Epicenter	Point directly above the focus of an earthquake
Strike-slip fault	Shearing causes horizontal movement along fault
Slab pull	When old and colder plates are pulled under newer ones
Reverse Fault	Compression forces plates to move in opposite directions (upward)
Normal Fault	Tension causes plates to slip horizontally downward
Tension	Stress that pulls rocks in two separate directions
Geohazard	Geological occurrences where land falls, moves, or shifts
Convergent boundary	When two plates push together in the same direction; often forms volcanic mountains
Focus	The point of the first rupture of a fault during an earthquake
Shearing	The shifting of two plates or rocks against one another
Theory of Continental Drift	The theory that the continents are slowly drifting apart
Ridge push	When lava hardens and pushes away old crust
Mantle convection	The circulation of warm less dense material and cold dense material
Asthenosphere	The lower part of the crust and upper part of the mantle
Tectonic Plate	Giant irregularly shaped slab of solid rock
Transform boundary	When two plates rub against each other in opposite directions; forms faults and causes earthquakes
Seafloor Spreading	When lava in the ocean hardens and forms a rock at a mid ocean ridge and pushes older crust back
Hot Spot	Hot areas on Earth's surface where plumes of mantle rise to the surface
Divergent boundary	When two plates are pulled apart/pushed apart and form ridges or rift valleys
