Earth? - ANSWER ✓✓✓Seismic Waves
Where do most earthquakes happen? - ANSWER ✓✓✓the boundaries of tectonic
plates
What is the Ring of Fire? - ANSWER ✓✓✓a spot located around the pacific plate that
has many volcanoes and earthquakes occur there.
What is a break in Earth's crust where blocks of rock slide relative to one another
called? - ANSWER ✓✓✓fault
What are the three types of crustal deformation? - ANSWER ✓✓✓elastic, shear,
tension, compression
Which deformation causes earthquakes? - ANSWER ✓✓✓elastic
, Which plate movement correlates with shear deformation? - ANSWER ✓✓✓Transform
Which seismic waves arrive first? - ANSWER ✓✓✓primary or p waves
Which seismic waves arrives second? - ANSWER ✓✓✓secondary or s waves
Which seismic waves do the most damage? - ANSWER ✓✓✓surface or l waves

What is the order of the layers of the Earth from innermost to outermost? - ANSWER ✓
✓✓Inner Core, Outer Core, Mesosphere, Asthenosphere (Mesosphere and
Asthenosphere make the mantle), Lithosphere (Crust)
Which layer of the Earth has the greatest density? - ANSWER ✓✓✓core
Which layer of the Earth has the lightest density? - ANSWER ✓✓✓crust
What is the theory of plate tectonics? - ANSWER ✓✓✓The Earth's crust is divided into
12 or more plates that shift and move based on their position on the plastic like layer of
the mantle.
What is the cause of the movement of the plates? - ANSWER ✓✓✓convection
currents in the mantle
What are convection currents? - ANSWER ✓✓✓The more dense material in the
mantle is heated, becomes less dense, rises and then cools, becomes more dense and
then falls back towards the core.
Which plate movement correlates with tension deformation? - ANSWER ✓✓✓
Divergent
What is evidence of seafloor spreading? - ANSWER ✓✓✓Magnetic striping along the
seafloor, polarity shifting, locations of old and young rocks.
