STAAR Plate Tectonics

Formed when magma cools beneath the Earth’s surface; requires heat

• sedimentary rock

• igneous rock

• metamorphic rock

• classic rock

Occurs when rocks are broken apart by physical processes

• deposition

• weathering

• erosion

Alfred Wegener believed landmasses of Earth once fit together to form a single landmass called “Pangaea”.

• Theory of plate tectonics

• Theory of continental drift

Occur when plates are moving apart

• transform boundary

• divergent boundary

• convergent boundary

Common site of geologic activity caused by moving plates

• earthquakes

• volcanoes

• plate boundaries

The movement of sediment; moves pieces of Earth from one place and builds land in another

• deposition

• weathering

• erosion

Where one plate moves under another

• subtraction zone

• sublimation zone

• subduction zone

NGSS.HS-ESS2-1

Made of crust and upper mantle; broken into tectonic plates

• asthenosphere

• inner core

• outer core

• lithosphere

Occur where plates come together; volcanic or folded mountains

• divergent boundary

• transform boundary

• convergent boundary

What is the layer just inside of the lithosphere; partially molten that allows convection currents?

• erosion

• mantle

• lithosphere

• asthenosphere
