Quiz/Review • Get out a small piece of paper and put your name on it. • When the bell rings, the quiz will begin.
Question 1 • What layer do we live on?
Question 2 • How do we know the outer core is liquid?
Question 3 • What does the rotating inner core create?
Answers • Crust • Earthquake seismic waves do not go through. • Magnetosphere
Mid-Ocean Ridges • Where the crust is pulled apart, allowing magma to rise in the crack further pushing the “plates apart”
Convergent plate boundaries • When crustal plates come together. • Density forces one plate to subduct or sink below the other. • The sinking plate melts and magma rises which creates a volcano.
Hot Spots • These are spots where magma rises to the surface and creates volcanoes and mountains. • Hawaii is the most famous. • Yellowstone hotspot!
Location • Most volcanoes occur at plate boundaries around the world.
