100
The three main types of vibration waves from an earthquake.
What are surface, P waves, and S waves?
100
Three factors that cause earthquake waves to do damage to buildings and other structures.
What are intensity and duration of waves, nature of material on which the structure is built, and the design of the structure?
100
Earth's interior consists of these major zones that are defined by their chemical composition.
What are the crust, the mantle, and the core?
100
This person created the continental drift hypothesis.
Who is Wegner?
100
The process by which plate tectonics produces new oceanic lithosphere.
What is seafloor spreading?
200
When energy stored in a rock has been subjected to great forces and the strength of the rock is exceeded, it suddenly breaks, causing this.
What is an earthquake?
200
This happens when a slab of the ocean floor is displaced vertically along a fault or when the vibration of a quake sets off an underwater landslide..
What is a tsunami?
200
Earth can be divided into these layers based on physical properties:
What are the lithosphere, asthenosphere, outer core, and inner core?
200
This states that the continents had once been joined to form a single supercontinent.
What is the Continental Drift Hypothesis?
200
This occurs when one oceanic plate is forced down into the mantle beneath a second plate.
What is subduction zone?
300
This device shows three main types of seismic waves.
What is a seismogram?
300
In many earthquakes, the damage to structures is from these events.
What are landslides or sinking of the ground?
300
The continental crust is made up primarily made up of this type of rock.
What is granitic?
300
This evidence for continental drift includes several fossil organisms found on different landmasses.
What is Fossil evidence?
300
Plates grind past each other without destroying the lithosphere.
What is a transform fault boundary?
400
This graph from three or more seismograms can be used to find the exact location of an epicenter.
What is a travel-time graph?
400
This has yet to be successful in earthquake science.
What are short-range predictions?
400
The oceanic crust is made up of this type of rock.
What is basalt?
400
According to this theory, the uppermost mantle, along with the overlying crust, behaves as a strong, rigid layer known as the lithosphere.
What is Plate Tectonics?
400
This occurring in the mantle is what scientists believe to be the basic driving force for plate movement.
What is convection?
500
Historically, scientists have used these two different measurement types to describe the size of an earthquake.
What are intensity and magnitude?
500
Scientists do not know enough about ____ and _____ earthquakes will occur to make accurate long-term predictions.
What are how and where?
500
These are the two elements that make up the dense core.
What are iron and nickel?
500
These are the three types of boundaries:
What are convergent, divergent, and transform?
500
This is thought to cause oceanic lithosphere to slide down the sides of the oceanic ridge.
What is Ridge-push.
