What precious material “rains” on Neptune and Uranus?
Gold
Pearls
Emeralds
Diamonds
As crazy as it may sound, scientists believe that diamonds “rain down” on both Neptune and Uranus. This phenomenon occurs because the atmospheres of these planets are filled with hydrocarbons, and under extreme pressure surrounding the planets’ cores, these hydrocarbons split into atoms of hydrogen and carbon, the latter of which then crystallize to form diamonds. While direct observations remain an unattainable feat due to the vast distance separating these planets from Earth, astrophysicists have replicated the “diamond rain” in a lab by simulating the necessary outer planet conditions.
The correct answer is Diamonds.
