Earthquakes Flashcards
What type of fault and stress are at a transform boundary?
strike slip, shearing
What layer of Earth do all earthquakes occur?
lithosphere
What is a break in Earth’s lithosphere, along which blocks of rock move past each other?
fault
What is a shaking of the ground caused by the sudden release of stress along a fault?
earthquake
What is the force exerted when an object presses on, pulls on, or pushes against another object?
stress
What type of fault and stress are at a divergent boundary?
normal, tension
What determines the strength of an earthquake?
amount of stress and distance rocks move
What type of fault and stress are at a convergent boundary?
reverse, compression
What is a bending of a wave from medium to medium?
refraction
What is the point IN Earth where the earthquake starts?
focus
What type of wave can travel through all layers of the Earth?
Primary waves (P-waves)
What type of boundaries could have deeper earthquakes?
convergent
What is a bouncing of a wave off an object?
reflection
What type of wave does the most damage to Earth’s surface?
surface waves
What is the point ON Earth where the earthquake starts?
epicenter
