Web1. How do scientists find the age of planets (date samples) or planetary time (relative age and absolute age)?We have rocks from the Moon (brought back), meteorites, and rocks that we know came from Mars. We can then use radioactive age dating in order to date the ages of the surfaces (when the rocks first formed, i.e. when the lava cooled and crystallized). … WebMay 10, 2024 · There are two main ways in which geologists have built an understanding of geological time by dating geological materials: absolute dating and relative dating. …
