Which hypothesis about the moon is supported by the samples of lunar rock that were collected by the apollo missions a the moon has always lacked geologic activity b the entire surface of the moon was once covered in water c the entire surface of the moon was once completely molten d the moon experienced extensive volcanic eruptions in the past

The hypothesis that the moon experienced extensive volcanic eruptions in the past is supported by the samples of lunar rock that were collected by the Apollo missions.

Explanation:

The Appollo missions came home with two distinct samples of rocks which were found at the landing site of the Appollo 11. These samples were taken from 13 centimeters below the Lunar surface and consisted of basalt and breccias rocks. The basalt rock sample that was found on the moon was identical in composition with the basalt rock that is commonly found on the Earth. It is observed that there is an abundance of basalt rock on the moon. Thus, it is concluded that the moon experienced extensive volcanic eruptions in the past.
