The Rock Record
The rock record is nothing more than the rocks that currently exist. The rock record does not show a tidy, orderly progression of geologic events. Rock formations are eroded, buried, torn apart, melted, squashed together, even turned upside down. This geologic record is the history of Earth as recorded in the rocks that make up its crust. Rocks have been forming and wearing away since Earth first started to form, creating sediment that accumulates in layers of rock called strata.
