Answer

Brief Explanations:

Large asteroid and comet impacts can eject a vast amount of dust into the atmosphere. This dust can block sunlight and have wide - ranging environmental effects, polluting the atmosphere. Continents moving is mainly due to plate tectonics, not asteroid impacts. Large impacts cause large craters, not small ones, and their effects are not limited to just within the crater as they can have global environmental consequences.

Answer:

They may kick up dust and pollute Earth’s atmosphere.
