Multiple choice

What is the Rare Earth Hypothesis?

  1. The hypothesis that life is common in the universe.

  2. The hypothesis that life is rare in the universe.

  3. The hypothesis that life is only possible on Earth.

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The Rare Earth Hypothesis proposes that the conditions necessary for the emergence of life are rare in the universe. This is in contrast to the common belief that life is abundant in the universe.

Multiple choice
