Quizplus · Accepted Answer

All of the given options are correct. If a large 10-km asteroid or comet struck the Earth in the ocean floor, it would cause massive forest fires due to the impact and the subsequent raining down of molten rock. Giant tidal waves from the impact would also result. The after-effects, including a thick cloud of dust from the impact, would block out the sun for an extended period leading to the deaths of most animal life on the planet.
