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.
