Question

Suppose a major tsunami occurred in the Pacific Ocean, impacting coastal areas. What impact would this natural event have upon coastal populations?

Populations would likely stay the same.

Populations would likely decrease.

Populations would likely increase.

Populations would likely fall and rise unpredictably.

Answer 1

Populations would likely decrease.

Step-by-step explanation:

Upon making contact with the shore, tsunamis can severely alter the coastal landscape through rapid erosion and deposition of sediment. High wave energy may transport coastal vegetation and marine debris and leave in place unstable barren dunes susceptible to further erosion.
