Why are there craters on the Moon?

Answer: Asteroids and meteors hit it

Asteroids and meteors hit it ✓ — Correct! Over 4 billion years, countless asteroids, meteors, and comets have crashed into the Moon at tremendous speeds (up to 45,000 mph), creating craters. The Moon has no atmosphere to burn up incoming objects and no weather or plate tectonics to erase craters, so they remain for billions of years. Earth gets hit too, but our atmosphere, oceans, and geological activity hide most impact evidence. The Moon is a preserved record of solar system bombardment.

The surface collapsed inward — Wrong. The craters aren't caused by surface collapse or sinkholes. They're impact craters formed by objects from space striking the surface at high velocity. The explosive energy creates the characteristic bowl shape with raised rims and sometimes central peaks.

Moon rocks exploded from heat — Wrong. Moon rocks don't explode from heat. The Moon's temperature varies from -173°C to 127°C, but this doesn't cause explosions. The craters are impact craters from space objects colliding with the Moon over billions of years at extremely high speeds.
