Vocabulary

Granite- The type of rock that makes up the continental crust Basalt- The type of rock that makes up the oceanic crust Oceanic Crust- The crust that is in the ocean Continental Crust- The crust that is above sea level Crust- The top layer of Earth’s 4

Mantle- The second layer of Earth; made of a plasticy solid material Outer Core- The third layer of Earth; the only liquid layer Inner Core- The inner most layer of Earth Divergent Boundary- Where two plates move away from each other

Convergent Boundary- Where two plates move together Transform Boundary- Where two plates move past each other Focus- The place where seismic waves originate Epicenter- Place directly above the focus on the surface Seismic Waves- Vibrations that carry energy on and in Earth

P-Waves- Primary waves; push-pull motion on particles in the ground S-Waves- Secondary waves; move in up and down right angles Surface Waves- Seismic waves on the surface; move in up and down rolling motions Fault- Break in Earth’s crust where rock slabs slip past one another Normal Fault- Fault with tension (pulls apart)

Reverse Fault- Fault with compression (pushed together) Strike Slip Fault- Fault with shearing (moving in opposite directions) Mid-Ocean Ridge- Volcanic arc in the oceanic crust Subduction Zone- The place where the oceanic crust goes under the continental crust Trench- The space between the oceanic

Sea Floor Spreading- The process where new rock replaces the old on the sea floor Shield Volcano- Sloping volcanic mountain that releases repeated quiet eruptions Cinder Cone Volcano- Cone shaped hill with that cinders erupt from it Composite Volcano- Layers of lava that

Volcanic Arc- A chain of volcanoes on land Hot Spots-
