100
This number is how many layers the Earth's interior has
What is 4?
100
Shield, Cinder, Composite
What are TYPES OF VOLCANOES
100
Crustal rocks fail when stresses exceed the strength of the rocks. The resulting movement occurs along a weak region in the crustal rock called this.
What is a FAULT
100
In areas with sand that is nearly saturated with water, seismic vibrations can cause the ground to behave like a liquid in a phenomenon called this
What is SOIL LIQUEFACTION
100
Vesuvius, Aetna, Kracatowa
What are FAMOUS VOLCANOES
200
This is the outer most layer of the Earth
What is the CRUST?
200
This is at the top of the volcano, around the vent, a bowl-shaped depression called this
What is a CRATER
200
The point on Earth's surface directly above the focus is called this
What is the EPICENTER
200
A large ocean wave generated by vertical motions of the seafloor during an earthquake.
What is a TSUNAMI
200
A vibration of Earth's crust
What is an EARTHQUAKE
300
Wegener proposed that this supercontinent had once been joined as a single landmass that broke apart and sent the continents adrift
What is PANGAEA
300
Hot regions of Earth's mantel where high-temperature plums of magma rise to the surface
What are HOT SPOTS
300
The total force acting on crustal rocks per unit of area.
What is STRESS
300
Sections located along faults that are known to be active, but which have not experienced significant earthquakes for a long period of time.
What are SEISMIC GAPS
300
Liquid rock inside a volcano
What is MAGMA
400
The evidence for seafloor spreading suggested that continental and oceanic crust move as enormous slabs, which geologists describe as this
What is TECTONIC PLATES
400
These can get up to 50km in diameter and form after the magma chamber empties.
What is the CALDERA
400
The deformation of materials in response to stress is called this.
What is STRAIN
400
The rate at which stress builds up in rocks
What is STRESS ACCUMULATION
400
Seismic, Primary, Secondary
What are WAVES
500
This is used to study and map the ocean floor
What is a MAGNETOMETER
500
Basaltic, Andesitic, Rhyolitic
What are the TYPES OF MAGMA
500
Devised by geologist Charles Richter, this numerical rating system measures the energy of the largest seismic waves produced during an earthquake.
What is the RICHTER SCALE
500
The intensity of an earthquake is determined by this
What is MODIFIED MERCALLI SCALE
500
The Pacific Ocean, where many of the world's earthquakes and volcanoes form.
What is THE RING OF FIRE
