Explanation / Answer

1. Brand new divergent boundaries are called?

a. Subduction zones

b. Rift Valleys

c. Central Valleys

d. Ocean-ocean convergent boundaries

ANSWER

b. Rift Valleys

Here pates are diverging from each other .

example – rift valleys in the east Africa is an example of divergent boundary .

2. According to the lecture, earthquakes deeper than the lithosphere is thick is considered:

a. A shallow earthquake

b. A hollow earthquake

c. A deep earthquake

d. A shear earthquake

ANSWER :

c. A deep earthquake

The earthquake having depth (focus distance from the surface of earth ) greater than 300 km is known as deep earthquake

3. At a seismic recording station directly on the other side of the planet from a major earthquake, earthquake waves will not be detected from that earthquake.

a. True

b. False

ANSWER

Explanation :

.” At a seismic recording station directly on the other side of the planet from a major earthquake, earthquake waves will not be detected from that earthquake.”

This statement is true because the earthquake wave can not reach directly opposite side of the point or side where earthquake occurs . because

P-wave shadow zone range is 103 to 143 degree .

So earthquake wave can not reach just opposite side earthquake focus point .

4. Small earthquakes along a fault line like the San Andreas fault help to relieve stress along the fault, thereby preventing a major earthquake in the future.

a. True

b. False

ANSWER :

b. False

Explanation :

small earth quake can just indicate major earthquake will be occurs in near future .

since maximum major earthquake are associated with number of small earthquake (this phenomena is call foreshock )

5. Earthquake intensity refers to:

a. The amount of energy released at the focus of an earthquake.

b. A measure of the degree of shaking at a given locale based on the amount of damage.

c. The distance you are at in relation to the epicenter of an earthquake.

d. The amount of energy released during a volcanic eruption.

ANSWER :

Explanation :

earthquake intensity dependence on the amount of damage not on the amount of energy release at the focus point .
