The location on Earth's surface directly above the earthquakes focus.
What is the epicenter?
100
Vibrations in the ground that result from movement along breaks in the Earth's lithosphere.
What is an earthquake?
100
A vent in the Earth's crust through which melted- or molten rock flows.
What is a volcano?
100
This is another word for "breaks" in the Earth's lithosphere.
What is a fault
100
The types of waves created by earthquakes.
What are seismic waves?
200
The type of fault caused by two blocks of rock being pushed together. They occur at convergent plate boundaries
What is a reverse fault.
200
Volcanoes that are not associated with plate boundaries.
What are hot spots?
200
A type of fault where plate slide horizontally past each other. They are also located at transform plate boundaries.
What is a strike-slip fault
200
An area of earthquake and volcanic activity that surrounds the Pacific Ocean.
What is The Ring of Fire?
200
These types of wave CAN NOT travel through liquid.
What are S-waves?
300
These types of wave move up and down in a rolling motion, similar to ocean waves?
What are surface waves?
300
Explosive volcanoes can produce fast moving avalanches of hot gas, ash and rock.
What is pyroclastic flow?
300
True or False. Earthquakes can be predicted?
False
300
These are the three types of faults?
What are strike-slip, normal and reverse?
400
This is a word describing the rising currents of hot mantle material.
What is a plume?
400
These are the three types of seismic waves?
What are S-waves, P-waves and surface waves?

An earthquake is California measure 1.2 on the Richter scale and an earthquake in Peru measures 2.2 on the Richter scale, how many times more powerful is the magnitude of the earthquake in Peru.
10 times greater.
400
An earthquake is California measure 2 on the Richter scale and an earthquake in Peru measures 5 on the Richter scale, how many times more powerful is the magnitude of the earthquake in Peru.
What is 1000 times greater
500
Give me two reasons for why ash is so dangerous during a volcanic eruption.
What is
1. Ash can disrupt air traffic.
2. Ash can affect air quality and cause breathing problems.
3. Ash can block sunlight, causing the temperature to drop.
500
Describe how the Hawaiian islands were formed.
A plume or hot spot deposited lava underground and formed an island. The tectonic plate moved and the hot spot/plume repeated the same process.

These are the three steps for triangulation.
What is 1.find the arrival time difference, 2. find the distance to the epicenter and 3. plot the distance on a map.
500
Name three of the for effects of volcanic eruptions.
