Final answer:
A tsunami can result in death, drought in coastal regions, and genetic changes in populations.
Step-by-step explanation:
One effect that would most likely result from a tsunami is death. Tsunamis can cause massive destruction, resulting in loss of life due to drowning, injuries, and being struck by debris.
Tsunamis can also lead to drought in coastal regions. The immense force of a tsunami can contaminate freshwater sources with saltwater, rendering them undrinkable and affecting agricultural activities.
Tsunamis can have significant impacts on marine ecosystems, but they do not typically lead to extinction of species. However, genetic changes may occur in some populations due to survival and adaptation mechanisms.
