Identify statements true of submarine landslides and tsunamis. Choose one or more:

A. Large submarine slides of rock or sediment can create earthquake waves, which can initiate a tsunami.

B. As a submarine slide occurs, it can result in a depression in the sea surface above the slide. A tsunami can form when water rushes in to fill the depression.

C. As a submarine slide occurs, it can push water into a sea-surface bulge ahead of its path; this can result in tsunami initiation.

D. Because submarine slides take place underwater, they do not displace surface water, and are thus not likely to result in tsunami initiation.

B & C

B. As a submarine slide occurs, it can result in a depression in the sea surface above the slide. A tsunami can form when water rushes in to fill the depression.

Explanation:

A tsunami is a wave or series of waves that occurs after abrupt disturbances that vertically displace the water column, such as an earthquake, volcanic activity, abrupt displacement of land or ice, or due to the impact of a meteorite in or near the sea.

Submarine landslides, which often accompany large earthquakes, as well as the collapse of volcanic buildings, can also disturb the water column when large volumes of sediment and rock shift and redistribute at the bottom of the sea. This can raise the water column and generate a tsunami.
