The Earth's Memory

The Earth has been around far longer than any living human, collecting experiences for millions, perhaps billions, of years. Of course, it can't tell us verbally about its history. But scientists have learned to study the earth to gain knowledge about the Earth's past. From the Earth's basement treasures, we can learn about previous weather conditions, lost civilizations, and even prehistoric eras!
