Each sedimentary layer of rock represents 1,000 years of Earth's age, much like the rings of a tree
In undisturbed layers of sedimentary rock, the lowest layers contain the older rocks
In undisturbed layers of sedimentary rocks, the upper rock layers are older than the lower rock layers
Rocks that form near volcanoes are older than the surrounding rock.

Saltwater fish are found in some mountain streams
Dinosaur bones have been discovered in the mountains
Marine fossils have been found on the peaks of some mountains

The diagram below represents a stack of rock layers. These layers have not changed position since they formed. If the age of layer 4 is 400 million years and the age of layer 1 is 500 million years, then the age of Layer 2 is
younger than 400 million years.
400 million years.
older than 500 million years.
between 400 million and 500 million years.

The shell is younger than the fish, and the same age as the bone.
The shell is the same age as the fish, and younger than the bone.
