Faults and Boundaries 2
100
A fold in rock that bends upward into an arch formed by compression is called a(n):
What is Anticline
100
The point on Earth’s surface directly above an earthquake’s focus.
What is epicenter
100
19. The number that geologists assign to an earthquake based on its seismic waves and movement along faults is called
What is Magnitude
100
A type of fault in which rocks on either side move past each other sideways with little up or down motion.
What is Strike-Slip Fault
100
A plate boundary where two plates move away from each other.
What is divergent boundary
200
A downward fold in the rock formed by compression is called a(n):
What is Syncline
200
The point beneath Earth’s surface where rock breaks under stress and causes an earthquake.
What is focus
200
Stress that pushes masses of rock in opposite directions, in a sideways movement.
What is shearing
200
Stress that stretches rock so that it becomes thinner in the middle.
What is tension
200
A plate boundary where two plates move toward each other.
What is convergent boundary
300
A stress force that squeezes rock until it folds or breaks, caused by one plate pushing against another is called:
What is A. Compression
300
A break in Earth’s crust where masses of rock slip past each other
What is fault
300
A scale that rates an earthquake’s magnitude based on the size of its seismic waves.
What is Richter Scale
300
A plate boundary where two plates move past each other in opposite directions.
What is transform boundary
300
The name of Mr. Snyder's favorite baseball team
What is the Yankees
400
used to measure earthquakes:
What is A. Seismograph
400
A type of seismic wave that compresses and expands the ground, the first ones to hit you in an earthquake
What is P wave
400
Stress that squeezes rock until it folds or breaks.
What is compression
400
A type of fault where the hanging wall slides upward; caused by compression in the crust.
What is reverse fault
500
Vibrations that travel through Earth carrying the energy released during an earthquake.
What are seismic waves
500
A type of seismic wave that moves the ground up and down or side to side.
What is S wave
500
A scale that rates earthquakes according to their intensity and how much damage they cause at a particular place.
What is Mercalli Scale
500
A type of fault where the hanging wall slides downward; caused by tension in the crust.
What is normal fault
500
