This volcano has gently sloping sides created by thin magma in which most of the gases have already escaped.
What is a shield volcano?
100
This theory proposed by Alfred Wegener states that the continents broke apart and traveled in time to their present day locations.
What is Continental Drift?
100
The amount of energy released from an earthquake.
What is magnitude?
100
This molten rock is above ground.
What is lava?
100
Magma heats underground water to form this eruption of hot water and steam.
What is a geyser?
200
This type of volcano is composed of layers of lava, hot rocks, and ash.
What is a composite volcano?
200
This model explains how new crust forms at ocean ridges.
What is sea-floor spreading?
200
The vibrations sent out from the focus during an earthquake.
What are seismic waves?
200
The place where earthquakes and volcanoes are most likely to occur.
What is plate boundary?
200
Energy from the Earth's heat.
What is geothermal?
300
This volcano has not erupted recently but has erupted in recorded history.
What is a dormant volcano?
300
At these boundaries, tectonic plates slide past each other.
What is transform boundaries?
300
The tool used to measure seismic waves.
What is seismograph or seismometer?
300
The cause of volcanoes that created the Hawaiian Islands.
What is hot spot?
300
An opening in the ground where hot water, heated by magma, and gases escape.
What is a hot spring?
400
This volcano is inactive and has not erupted in recorded history.
What is an extinct volcano?
400
The idea that Earth's crust is broken in the plates that move slowly across the mantle.
What is Plate Tectonics?
400
The 1-10 scale used to measure the magnitude of an earthquake.
What is the Richter Scale?
400
The name of the supercontinent of Wegener's theory Continental Drift.
What is Pangaea?
400
The layer of the earth below the crust where magma can be found.
What is the mantle?
500
This type of volcano is formed as gases and lava explode out and build up a steep-sided cone.
What is a cinder cone volcano?
500
The process of plates colliding resulting in the denser plate sliding under the other plate.
What is subduction?
500
The point on the ground where an earthquake is first detected.
What is the epicenter?
500
A hot, muddy pool of hot water, rock and minerals that look yellow, red, and black.
