The study of earthquakes
What is seismology?
100
can travel through solids, liquids, and gases.
What is primary seismic waves?
100
An instrument located at or near the surface of the Earth that records seismic waves.
What is a seismograph?
100
three. Two seismograph stations narrow the location of an earthquake. Adding a third enables scientists to determine which location is correct.
How many seismograph stations are needed to use the S-P time method?
100
States that sections of active faults that have had few earthquakes are likely to be the sites of strong earthquakes in the future.
What is the gap hypothesis?
200
A break in the Earth's crust along which blocks of the crust slide relative to one another
What is fault?
200
convergent plate boundaries.
What is the plate where the strongest earthquakes occur?
200
A tracing of earthquake motion created by a seismograph.
What is a seismogram?
200
strong, wide base, cross braces, flexible pipes.
What are ways in which buildings are reinforced against earthquakes?
200
An area along a fault where relatively few earthquakes have occurred.
What is a seismic gap?
300
The change in the shape of rock in response to stress.
What is deformation?
300
The strength of an earthquake, location of the epicenter, and learn about the internal structure of the earth.
What are things seismologists can learn from studying seismic waves?
300
The point on the Earth's surface directly above an earthquake's starting point.
What is the epicenter?
300
nonperishable food, water, fire extinguisher flashlight with batteries, first-aid kit.
What are items that should be stored in case of an earthquake?
300
A place within the Earth where the speed of seismic waves increase sharply; marks the boundary between the Earth's crust and mantle.
What is Moho?
400
Waves of energy that travel through the Earth.
What is seismic waves?
400
rock releasing energy during elastic rebound.
What is the direct cause of an earthquake?
400
The point inside the Earth where an earthquake begins.
What is the focus?
400
David, Brian and Sean (in spirit).
Who built the tallest building that withstood Mr. Merkord's earthquake?
400
An area on the Earth's surface where no direct seismic waves from a particular earthquake can be detected.
