Question

Shallow earthquakes, less than 20 km deep, are associated with _______
a) convergent plate boundaries
b) divergent plate boundaries
c) transform plate boundaries
d) all of these

Answer 1

Answer:

i think answer is ( d )...

Answer 2

Shallow earthquakes, less than 20 km deep, are associated with _ divergent plate boundaries___

• shallow earthquake are earthquake of low magnitude.
• they occur at the depth of 0-70 km.
• they occur at the divergent plate boundaries where the two oceanic plates move away from each other and also at the middle of the continent rift zones.
• these are less deep and occur at the earth's outer crustal layer.
• divergent boundaries are places where two plates are drifting apart and a new crust are formed due to the pushing of magma at the mantle.

hence, the correct option is b) divergent plate boundaries
