EARTHQUAKES

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What type of boundary do earthquakes most frequently occur along?
A
transform and convergent
B
divergent and transform
C
convergent and divergent
D
None of the above
Explanation: 

Detailed explanation-1: -Transform boundaries are where plates slide past one another. Also called faults, they usually happen where two ocean or two continental plates meet. They are most common on the ocean floor. These plates are colliding with huge force, causing one to slowly grind over, under or alongside the other.

Detailed explanation-2: -About 80% of earthquakes occur where plates are pushed together, called convergent boundaries. Another form of convergent boundary is a collision where two continental plates meet head-on.

Detailed explanation-3: -Transform boundaries typically produce large, shallow-focus earthquakes. Although earthquakes do occur in the central regions of plates, these regions do not usually have large earthquakes.

Detailed explanation-4: -Oceanic-Continental Convergent Boundary. Figure 2.4. 3. At a convergent boundary between oceanic and continental lithosphere, the oceanic plate will always subduct, which will cause earthquakes and form volcanic arcs.

Detailed explanation-5: -Transform plate boundaries produce enormous and deadly earthquakes. These quakes at transform faults are shallow focus. This is because the plates slide past each other without moving up or down. Studies show that big quakes occur every 125 years or more.
