Stratigraphers study strata. These are the rock layers that hold the key to earth history. In the Grand Canyon, strata are like a book of the geologic history of Northern Arizona. Stratigraphy is important in other regions, but is usually not so well displayed.
Why It Matters
- Sedimentology is the interpretation of how sedimentary rocks are deposited.
- Many geologists are hired with a bachelors or masters degree. A doctorate is usually needed for a research science career.

- Why is it important for geologists to study all the strata of a region rather than just one sedimentary rock layer?
- Which industries hire stratigraphers? What information do they need from stratigraphers?
- What work does a stratigrapher do after he returns from the field?
- What sorts of scientific questions does a stratigrapher seek to answer?
