C) Earthquake
D) Convergent Boundary
E) Volcano
F) Convection cell
G) Divergent Boundary
___c Movement of crust or rock
___ g Where two plates are moving apart
___ e Where molten rock has made it’s way to the surface
___b The study of the movement of large pieces of crust across the planet
___ a Where two plates move side by side
___ d Where two plates collide with each other
___ f Movement of heated material in a circular motion within the Mantel of the planet
Q: Where do earthquakes and volcanoes usually occur?
Plate boundaries
Q: Which form of energy drives the earth geologic processes?
Heat energy (within the core due to radioactive decay, heat moves up, up
means out into the mantel. Convection cells turning breaks the crust apart into the
plates)
Q: Both the Andes mountains and the Himalayan mountains were formed by the same
event/feature called:
Convergent plate boundary (plates colliding; collision along plate boundaries
causes mountain building)
Q: Which event would involve a greater release of energy?
-A magnitude 7 earthquake *******
-A magnitude 3.7 earthquake
Q: Energy from an earthquake is sent to surrounding areas by what?
Waves
Q: Give an example to prove that not all faults are at plate boundaries:
Wasatch fault, water pocket fold (capitol reef)
Q: If the pressure at a fault builds up beyond the level that the fault can withstand, what
will occur?
Earthquake
Q: A dormant volcano has been bulging at the surface and numerous earthquakes have
been felt at the mountain. Both of these facts are evidence that what is about to happen:
An eruption
Q: Draw in the line graph that shows a volcanic eruption that is preceded by one
earthquake several days prior:
Amount of
Energy
released
Time in days
-First energy peak is earthquake second is eruption
Q: What were some of Alfred Wagener’s evidence that continental drift was happening:
-matching fossils on different continents
- continents seem to fit together (think African and South America)
