earthquake measurment
100
the point on the Earth's surface directly above an earthquake's starting point.
What is an epicenter
100
the change in the shape of rock in response to stress.
What is deformation
100
strike slip faults occur at transform boundaries.
What type of fault type occurs at transform boundaries.
100
a seismic wave that causes particles of rock to move in a back and fourth direction.
What are P waves
100
was used to measure the strength of earthquakes and was created in the 1930s.
What was the Richter Magnitude Scale?
200
the point inside the Earth where an earthquake begins.
What is focus
200
rock that changes shape but will not return to its original shape.
What is plastic deformation
200
reverse fault
What fault type occurs at convergent boundaries.
200
seismic waves that travel along Earth's surface.
What are surface waves?
200
a measure of the degree to which an earthquake is felt by people and the amount of damage caused.
What is intensity?
300
instruments located at or near the surface of the Earth that record seismic waves.
What are seismographs
300
when rock returns to its original shape even when broken.
What is Elastic deformation
300
normal fault
What fault type occurs at divergent boundaries?
300
a seismic wave that causes particles of rock to move in a side to side direction.
What are S waves
300
a measure of the strength of an earthquake.
What is magnitude?
400
a tracing of earthquake motion and is created by a seismogram.
What is a seismogram
400
occurs when more stress is applied to rock than the rock can withstand.
When does elastic rebound occur?
400
transform,convergent,and divergent
What are all the different types of tectonic plate boundaries?
400
a wave of energy that travels through the Earth.
What is a seismic wave?
400
a numerical scale that uses Roman numerals from I to XII to describe increasing earthquake intensity levels.
What is the Modified Mercalli Intensity Scale
