100
Pulls on crust, stretching rock
What is tension?
100
Waves that go side to side
What are s-waves?
100
Cooler, slower moving lava
What is aa?
200
Process of moving hot mantle towards the surface and cooler mantle down and moving the plates above it

200
Waves that are fastest and go back and forth
What are p-waves?
200
Area where material in mantle rises and melts forming magma, and creating a volcano
What is hot spot?
300
Layer of the earth that is high in heat and pressure and is solid
What is inner core?
300
Two plates slide past each other causing earthquakes
What is transform?
300
Plates move past each other
What is strike slip fault?
300
Area beneath earth's surface where rock that is under stress breaks, triggering an earthquake
What is focus?
300
Stages of volcanic activity
What are active, dormant, and extinct?
400
Process in the ocean where new crust is added to each side of a ridge and pushes older crust outward
What is seafloor spreading?
400
Two ocean plates come together and form a deep ocean trench
What is convergent, subduction?
400
Rock pushed together, hanging wall slides up
What is reverse fault?
400
Using the distance from 3 earthquakes to the focus can help you triangulate this

400
Type of gas in volcanoes
What is carbon dioxide?
500
Process where crust sinks back into the mantle at a convergent boundaries
What is subduction?
500
Two plates come together and the ocean plate sinks under the continental creating a volcanic arc
What is convergent subduction?
500
Squeezes rock until it folds or breaks
What is compression?
500
Scale for intensity of eartquakes
What is magnitude?
500
Location under earth where magma is stored
What is magma chamber?
