Question

a scientist discovers a deep bowl - like divot under the ocean off the coast of eastern mexico that is many kilometers across. the layers of the ground all around the continent from around the time that structure formed contain large amounts of iridium and a larger number of fossils than is normally found. what most likely caused the bowl - like structure?
○ a comet
○ a meteorite
○ an iridium spike
○ a kuiper object impact

Explanation:

The presence of large amounts of iridium and a high - number of fossils around the time of the formation of the bowl - like structure is strongly associated with a meteorite impact. Iridium is rare on Earth's surface but common in meteorites. A major meteorite impact can cause mass extinctions and leave behind such geological and fossil evidence. Comets can also contain iridium but meteorites are more commonly linked to such large - scale impact structures. An iridium spike is an indication of an impact rather than the cause of the structure. Kuiper objects are in the outer solar system and impacts from them are less likely to cause such structures on Earth compared to meteorites.

Answer:

B. a meteorite
