Question

which space exploration activity has most helped astronomers determine the age of the moon? (1 point)
collection of lunar rock samples
experiments performed on the international space station
collection of deep space images by the hubble telescope
placement of mirrors on the lunar surface

Explanation:

To determine the age of the Moon, analyzing lunar rock samples is crucial. Lunar rocks contain isotopic and geological evidence that can be dated. Experiments on the ISS, Hubble images, or mirror placement don't directly provide age - determining data about the Moon's formation. So the collection of lunar rock samples is the key activity.

Answer:

A. collection of lunar rock samples
