Question

Which of the following hazards would you expect to see at a CONVERGENT plate boundary associated with a continent-continent COLLISION zone?
A. moderate strength earthquakes; non-explosive volcanic eruptions; flooding if volcanoes erupt underwater such as in Iceland
B. large earthquakes; explosive volcanic eruptions; landslides and flooding due to long chain of volcanic mountains
C. large earthquakes; no volcanoes; landslides and flooding due to the large plateau of very high mountains
D. large earthquakes; no volcanoes; flooding if the plate boundary is hilly

Answer 1

Answer:

Option (C)

Explanation:

The sharing of a convergent plate boundary between two continental plates results in the formation of a sandwich pattern, where the rocks at the edges of both the plates are crushed and crumbled and folded. Here the magma beneath the plates cannot rise up to the surface due to its high thickness, so it does not lead to the formation of volcanoes. For example, the Himalaya.

There is the possibility of occurring frequent landslides at the higher elevated mountainous areas due to the steeper slope of the mountains. It can also lead to the occurrence of flood, as there is the presence of plateaus that are formed at the top of the mountains that has the ability to trap water within them.

Thus, the correct answer is option (C).
