1. Intensity is to Damage while Magnitude is to _________
A. Wave
B. Amplitude
C. Energy
D. Force
2. Which of the following measures of an earthquake will decrease when observed farther from the epicenter?
A. Intensity
B. Magnitude
C. Depth of the focus
D. Location of the epicenter
3. What happen to the magnitude and intensity as measured farther from the epicenter?
A. Magnitude increases while intensity decreases
B. Magnitude decreases while intensity increases
C. Magnitude increases while intensity remains constant
D. Magnitude remains constant while intensity decreases
4. Is intensity 2 and magnitude 2 of an earthquake the same? Why?
A. No, because intensity is a measure of an earthquake in terms of energy while magnitude is a measure of the damaged caused by an earthquake.
B. No, because intensity is a measure of the severity of damaged caused by an earthquake while magnitude is a measure of energy released.
C. Yes, because both intensity 2 and magnitude 2 are considered weak vibration of the ground and can hardly felt by people, D. Yes, because both have equal quantity thus, they can be interpreted similarly.
5. Which of the following statements are TRUE?
I. Magnitude is a measure of seismic energy while intensity is a measure of damage.
II. Magnitude decreases with increasing distance while intensity remain constant.
III. Magnitude can be measured by an instrument while intensity is by observation.
A. I and II only
B. II and III only
C. I and II only
D. I, II and III
6. Report Non-Sense

3.B
4.C
5.B
Since A is dimmer than B, and brighter stars have lower magnitudes, the apparent visual magnitude of B must be 7 - 5 = 2. Star B is thus a second magnitude star. Q: Star A has a magnitude of 2.5, and star B has a magnitude of 4.5...
