Earthquakes
What causes earthquakes?
Plate movement as plates push on each other and volcanic activity.
What causes volcanic eruptions
earthquakes, plate movement, and pressure
What causes tsunamis
Earthquakes
What are the three types of rock?
Igneous, Metamorphic, and Sedimentary
What is the definition of geologist?
A person that studies the Earth and it's changing processes
Where do earthquakes occur?
At the plate boundaries
Where do you find the most volcanoes?
The ring of fire
How does a tsunami reach equilibrium?
Releasing the extra energy from the earthquake into a big wave
Igneous and sedimentary rocks exposed to heat and pressure
Define lava
hot, molten rock
what is the energy earthquakes produce when they create vibration
Seismic energy
Why are the volcanoes around the Ring of Fire
It is on the plate boundaries
what is the origin of the word tsunami
it is a Japanese word
What are the three layers of earth from thickest to thinnest?
Mantle, core, crust
Define Seismic
The energy of earthquake vibrations
How does an earthquake release energy to go back to equilibrium
by shaking the earth
How did the Hawaiian Islands form?
Volcanic activity underwater- erupting repeatedly over a long period of time to create a landmass
What do tsunamis look like out in the middle of the ocean?
A large, broad wave
How does equilibrium help us understand natural hazards?
Natural hazards occur as a way to release excess energy.
Define fossil
the remains or impression of an organism preserved in petrified form in rock

What is continental drift and how did it help scientists understand where fossils were?
The continents used to be one big continent that eventually broke into pieces, thus resulting in animals living on different continents.
Define equilibrium
The process by which something releases extra energy in order to move back to its original state
