5 True/False Questions
Define Shearing → Pulls crust; stretching rock so that it becomes thinner in the middle.
What is stretching? → A force that acts on a rock to change its shape or volume
How does a Seismograph work? → Scientists read the jagged lines a seismograph makes and interprets the seismic waves produced by the earth.
Explain comparing magnitudes → each number on the richter scale is 32x the previous one. Effects of an earthquake increase with magnitude.
gps satellites → measures change in elevation, tilt of land and horizontal movement
