Question

Quizplus · Accepted Answer

Meteor showers are indeed usually annual events because they occur when the Earth passes through the same region of space debris (often left behind by comets) at certain times of the year, aligning with the explanation in choices A and C. While asteroids can contribute to meteor activity, the classic meteor showers are more commonly associated with the debris from comets, not specifically Earth-grazing asteroids.
