At several locations on the northwest coast of North America are formations known as chevronswedge-shaped formations of mounded sedimentpointing toward the ocean. Most geologists take them to have been formed by erosion, but recently other scientists have proposed that they were thrown up from the ocean by massive waves triggered by meteor impacts in the Pacific Ocean.
Which of the following, if discovered, would most help in deciding which hypothesis is correct?
A) Chevron-like structures which are not currently near glaciers, large rivers, or other bodies of water
B) The presence, in chevrons, of deposits of ocean microfossils containing metals typically formed by meteor impacts
C) Oral-history evidence for flooding that could have been caused by ocean waves
D) The fact that exact data about the location and depth of any meteor impact craters on the Pacific seabed is lacking
E) The fact that certain changes in the shape and location of maritime sand dunes have been produced by the action of wind and waves
