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?\n a comet\n a meteorite\n an iridium spike\n a kuiper object impact
Answer
Answer:
B. a meteorite
Brief Explanation:
The presence of iridium and an abundance of fossils around the time the structure formed is consistent with a large - scale impact event. Meteorite impacts are known to cause such features and can lead to the deposition of iridium (which is rare on Earth's surface but more common in meteorites) and mass - extinctions (explaining the fossil abundance). Comets are less likely to cause such a well - defined, large impact structure in this context. An iridium spike is a result of an impact, not the cause of the structure. Kuiper objects are typically far from Earth and impacts from them are extremely rare and not the most likely cause here.
