Part 1
A force that acts on a rock to change its shape or volume is called...
What is stress?
The type of stress force that produces a strike-slip fault is...
What is shearing?
Shearing pushes rocks sideways in opposite directions, creating a...
What is a strike-slip fault?
An instrument used to measure and record ground movements during an earthquake is called a ...
What is a seismograph?
This occurs when an earthquake's shaking turns loose soil into mud.
What is liquefaction?
A break in the crust where slabs slip past each other is a ...
What is a fault?
The type of stress that pushes masses of rock sideways in opposite directions is...
What is shearing?
Tension pulls on rocks, creating a ...
What is a normal fault?
These waves arrive at a seismograph after P waves...
What are S waves?
Water displaced by an undersea earthquake may produce...
What are tsunamis?
Anticlines and synclines are two types of...
What are folds?
Compression tension and shearing are three types of ... that cause changes in the crust.
What is stress?
Compression squeezes rock until it breaks, creating a...
What is a reverse fault?
This scale is a rating system that estimates the total energy released by an earthquake...
What is the moment magnitude scale?
A base-isolated building design does this...
It reduces the amount of energy that reaches the building during an earthquake.
A type of fault that forms when the hanging wall moves upward past the footwall...
What is a reverse fault?
Doing this to the crust produces anticlines and synclines.
What is folding?
These waves arrive first at a seismograph...
What are P waves?
This scale rates earthquakes based on the intensity on building and land at a certain location...
What is the Mercalli scale?
This scale rates earthquakes based on the size of their seismic waves...
What is the Richter scale?
The force that pulls on the crust and stretches rock is...
What is tension?
A large area of flat land that is elevated high above sea level is known as a ...
What is a plateau?
The point beneath Earth's surface where the crust breaks and triggers an earthquake is called the...
What is the focus?
The point on Earth's surface directly above an earthquake's focus is called the...
What is the epicenter?
This scale rates earthquakes by estimating the total energy they release...
What is the moment magnitude scale?
