The practical applications of the study of tree rings are numerous.Dendrochronology is an interdisciplinary science, and its theory and techniques can be applied to many applications. These research interests have in common the following objectives: Ring-counting does not ensure the accurate dating of each individual ring.
The tree rings on Methuselah and other trees result from the annual growth cycle.A continuum of cell growth size can therefore be seen for each year.The sizes of each ring depend on many factors, including location, temperature, soil condition, wind, snow accumulation, sunlight, land gradient, and tree physiology.Modified with permission from Global Change: Time and Cycles, Department of the Interior, U. Students will be able to recognize the direct impact of climate on annual tree growth patterns. In this activity, students will use pre-marked paper strips to simulate tree-ring core samples to help them understand that data for past climate changes can be gathered from sources beyond long-term weather observations.
