What is a volcano?
A volcano is a vent in Earth's crust through which melted or molten rock flows.
100
What is an earthquake?
Earthquakes are the vibrations in the ground that result from movement along Earth's lithosphere. These breaks are called faults.
100
What are seismic waves?
Seismic waves are a release of energy that travel as vibrations on and in Earth. :)

What is a mudflow?
When melted water mixes with mud and ash on the mountain to form a mudflow.
100
What is pumice?
Pumice is a rock that is formed by the rapid cooling of lava from volcanoes that has lots of holes and is very lightweight.
200
Where most do volcanoes form?
Most volcanoes form along convergent and divergent plate boundaries.
200
What are the three types of faults?
Strike-slip, Normal,and reverse.
200
Does this definition match a primary wave or secondary wave?
These waves cause particles in the ground to move in a push-pull motion, similar to a coiled spring.
Primary Wave
200
What are the effects of ash fall?
It can disrupt air traffic, air quality, and climate.
200
What is the most famous fault called in California?
San Andrea fault
300
Which type of volcanoes are small, steep sided, and erupt with gas-rich balsaltic lavas?
Cinder Cones
300
Where do earthquake originate?
The waves originate where rocks first move along the fault at a location inside Earth called the focus.
300
Where is the energy from a wave strongest?
The epicenter
300
What is this?
A lava flow.
300
What does the Modified Mercalli scale measure?
Earthquake intensity based off of the damage
400
Volcanoes that are not associated with plate boundaries are called....
🌋HOT SPOTS🌋
400
Does this definition match a seismogram, seismologist, or seismometer?
A graphical illustration of seismic waves.
Seismogram!!!!!!!
400
Name two properties of surface waves.
(Name Two)
-Cause rock particles to move in a rolling or eliptical motion in the same direction that waves travel
-Slowest seismic wave
-generally causes the most damage
400
What is viscosity?
Viscosity is when a liquid resists flow.
400
What type of volcano's eruption formed Hawaii?
🌋HOT SPOTS🌋!

Name one affect volcanoes have on climate change.
-The volcanic ash in the atmosphere blocks sunlight, high altitude wind can move ash around the world
-The sulfur dioxide gases released from a volcano form sulfuric acid droplets in the upper atmosphere.
-The sulfuric acid droplets reflect sun into outer space lowering temperatures
500
What is triangulation?
Triangulation is the process used to locate an earthquake. It uses the distance information collected from three seismic stations to locate an earthquake.
500
What type of waves cannot go through liquid?
Secondary waves
500
What are properties of pyroclastic flow?
These explosive volcanoes can produce fast moving avalanches of hot gas, ash, and rock.
They are fast moving up to speeds of 100 km per hour.
It can reach temperatures up to and great than 1000 degrees celsius.

B.) Hawaii
C.) Washington
D.) California
A.) New York
