Explanation / Answer
1. What structure do earthquakes happen along?
c. Faults
It is the faults or cracks on Earth surface where two or more plates or the section of plates are moving in different directions and causing earthquakes.
Dike is a deposition of lava across the preexisting rock body.
Joints are the fracture on the earth surface with no displacement.
Unconformities are the buried erosional surface.
Folds are associated with bending or curving of the strata as a result of deformation.
So it can be concluded that only faults are associated with the displacement of plates and are the reason behind earthquakes.
2. In which order do earthquake waves arrive at a seismic station?
a. P-waves, then S-waves, then surface waves
As the name suggests P waves are primary waves so they come first, S-waves are secondary waves so they are second in position and then comes the most destructive surface waves.
3. Of the choices below, which choice is not associated with earthquake destruction?
b. High winds
The earthquake destruction is associated with Fire, Mass wasting, Trembling and Tsunami, so it is only the high winds which is not associated with earthquakes.
4. Which of the earthquake waves listed below cause the most amount of damage during a seismic event?
c. Surface waves
Surface waves have a lower frequency than P and S waves but are most destructive in nature. They move along the surface body of the earth like ripples.
