Question

1. pockets of ice on the moon are evidence of which of the following?

that pieces of earth form the moon
that samples were placed on the moon during apollo missions
that chemical reactions were caused by exposure to the sun
that collisions occurred with meteors and comets

Explanation:

Pockets of ice on the Moon are most likely from collisions with meteors and comets, which carry water ice. The other options are inconsistent: Earth's formation of the Moon doesn't directly explain ice pockets; Apollo missions didn't place ice samples; solar exposure would sublimate ice, not form it.

Answer:

that collisions occurred with meteors and comets
