Ch. 5 Earthquakes

QuestionAnswer
seismology the study of earthquakes
seismograph instrument used to record seismic waves
seismogram tracing of seismic waves by a seismograph
seismic waves waves of energy that travel through the Earth
body waves seismic waves that travel through the Earth's interior
surface waves seismic waves that travel along the earth's surface
P Waves -fastest -first to arrive -pressure waves -travels through solids, liquids, and gas
S Waves -second to arrive -shearing waves -only travels through solids
Earthquake Hazard how prone an area is to experience an earthquake
How is an area's EQ Hazard Level determined? by the area's past and present seismic activity
S-P time method used by seismologists to determine an EQ's epicenter
epicenter the location on the Earth's surface, directly above the focus, where an EQ occurs
focus location within the Earth where an EQ occurs
How many seismograph stations are required to find an epicenter and why? 3, because one will give too many possibilities, two narrows it to two possible epicenters and three pinpoints the exact location
Moho point between the crust and mantle where seismic waves speed up
shadow zone place on the Earth's surface where no seismic waves from a specific EQ can be detected -lead to the discovery of a liquid outer core
gap hypothesis the theory that areas along an active fault line that have little seismic activity will be the locations of future earthquakes
seismic gaps locations along an active fault line with little seismic activity
fault a break in the Earth's crust
strongest earthquakes usually occur deep within the earth at what type of boundary? Convergent
elastic rebound when rock breaks and immediately snaps back to its original shape -the direct cause of EQs
elastic deformation when rock bends and breaks elastically, causes EQs
plastic deformation when rock bends and stays bent, does not cause EQs

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
