1.
Know how scientists find the epicenter of an earthquake using triangualtion. Include differences in arrival times of waves and distances from epicenter in your explanation.: Scientists use seismic waves to locate an earthquakes epicenter by which waves come at different times, p waves, s waves, surface waves
2.
Know the 4 instruments geoglists use to measure movements along faults and how each one works: Tiltmeters- Measures vertical movement
Creep Meters- Measures movement
Laser-Ranging device- Measures horizontal movement
GPS Satellite- Measures changes in elevation and tilt of land along with horizontal movement
3.
Know the three scales used to measure earthquake damage, what each measures, and the scale they use: Richter--Magnitude
Mercalli--Earthquake's level of damage
Moment Magnitude--Estimates total energy released
4.
Know the three types of energy waves released by an earthquake: P Wave-- 1st-- Compress and Expand
S Wave-- 2nd-- Side to Side
Surface Wave-- 3rd-- Up and down; Side to side
5.
Know what anticlines and synclines are: Anticline- A fold in rock that bends upward into an arch
Syncline- A fold in rock that bends downward to form a valley
6.
Know what kind of stress that causes earthquakes, their movement, and the type of faults they produce: 1. Tension--Diverge---Normal
2. Compressional--Converge--Reverse
3. Shearing--Slip past each other--Strike--Slip
7.
What are safety measures one can take if indoors when an earthquake strikes?: 1.Drop, cover, hold
2. Crouch against an inner wall
3. Crouch beneath a desk or table and hold on
4. Move away from windows, doors, hanging objects, loose objects
8.
Why is it hard to predict earthquakes?: We do not have enough data and equipment to determine when may earthquakes come
