What is an earthquake?
A sudden violent shaking of the ground, sometimes causing great destruction.
100
What is the focus of an earthquake?
Where the earthquake begins. The ground ruptures at this spot.

What is the "Ring of Fire"?
The "Ring of Fire" is a string of volcanoes along the edges of the Pacific Ocean. Many volcanoes occur along this ring.
200
What are plate boundaries?
The location where 2 tectonic plates meet.
200
Where do we often find volcanoes?
Subduction zones or along tectonic plate boundaries.
200
What is a fault?
A break in the Earth's crust.
200
What is a tsunami?
A seismic sea wave.

Give 2 facts about one of the earthquakes that was researched in class.
Haiti
Earthquake of San Francisco
Earthquake of Sichuan
300
How are volcanoes and earthquakes linked to plate boundaries?
Volcanoes and earthquakes occur along plate boundaries because of tectonic plates.
300
Describe a cinder cone volcano.
A cinder cone volcano has steep hills, and they shoot lava and magma out of 1 vent.
300
Describe the Richter Scale.
The Richter Scals measures the intensity of earthquakes from 1-10.
300
What is the epicenter of an earthquake?
The point on the earth's surface that is located above the focus of the earthquake.
300
Where is the core of the earth located.
In the center.
400
What happens at a convergent collision boundary?
Two continental plates collide, creating mountains.
400
Name 2 positives and 2 negatives of volcanoes.
Positives: Create new life, create mountains, etc.
Negatives: Extremely dangerous, destroys everything in their path.
400
Describe a normal fault.
When the hanging wall of the earth slips down below the foot wall. Occurs when 2 blocks of rock are pulled apart.
400
What is a shield volcano?
A volcano that has many layers and erupts thin lava that flows like water.
400
Come up and label 3 parts of a volcano.
Ash, volcanic bombs, lava layers, magma chamber, secondary vent, etc.

What is Pangea?
Pangea was a supercontinent that existed during the Paleozoic era. It was formed about 300 million years ago and was the theory that all 7 of the earth's continents were connected.
500
Describe a stratovolcano.
Stratovolcanoes are very explosive. They shoot hot ash and thick lava out of several vents.
500
Describe a sliding/transform fault.
When 2 tectonic plates slide past one another.
500
What is a divergent plate boundary?
A plate boundary that moves apart and separates and leaves a gap.
500
Describe a Reverse Fault.
A Reverse Fault is when the hanging wall of the earth's crust moves up above the foot wall. This occurs when 2 blocks of rock are forced together.
