Which celestial phenomenon is primarily responsible for meteor showers when Earth passes through their debris?

• A. Asteroids
• B. Comets
• C. Star clusters
• D. Galaxies

Answer: (B)

Meteor showers occur when Earth passes through the debris left behind by comets. As a comet orbits the Sun, it sheds material, such as dust and small fragments, which become trapped in its orbital path. When Earth travels through this path, the tiny particles enter the atmosphere at high speeds, burning up and creating the streaks of light we observe as meteors. This process is particularly evident during specific times of the year when Earth intersects with the debris trails of known comets, leading to increased meteor activity, often associated with annual meteor showers.

Asteroids, while they can contribute to meteor activity, primarily do so through larger impacts rather than the organized showers linked to cometary debris. Star clusters and galaxies do not contribute to meteor showers as they are too distant and do not have debris that interacts with Earth in this manner. The unique relationship between Earth and comets in terms of debris trails is what makes comets the primary source of meteor showers.
