Question

Iridium is not found naturally on the surface of Earth but is found in asteroids, meteors, and comets.

• A. True
• B. False

Answer 1

The correct option is A

True

Iridium is an element found only in comets, meteorites, and asteroids. It is not found naturally on the surface of Earth at all. Its discovery in the samples of clay from some places led scientists to propose a theory that a large asteroid must have hit the Earth which could have been responsible for a mass extinction.
