Unformatted sample text from the term paper:
for millions of years, dendrochronology, becomes one of the tools of choice for the Quaternary Geologist. The ability to date a tree gives the geologist and archeologist a truer picture
of what types of plants might have lived during this distant past, as well as hinting at the type of climate that existed at the time. Over the last few
decades, as technology has continued to add to the abilities of scientists, the ability to utilize dendrochronology has become indispensable to the historical detective. Basically, dendrochronology is the dating of
past events through the study of tree ring growth. How this is possible is that scientists discovered that certain species of trees grew wider rings during wet years and narrower
rings when the climate was drier. Also, scientists knew that each year a tree would add a layer of wood to its trunk to support the additional growth. Additionally,
new wood is produced from the cambium layer between the old and new wood and such growth is most rampant during the Spring when the moisture is most plentiful(Cook 1990).
Scientists observed that as the seasons progressed and less moisture was available, that the new growth cells began to slow. It is this contrast between the smaller old cells and
the next years new growth cells that make this tree ring and make the dating possible(Easerbro 2004). Working backward through the process, then, the paleobotonist assumes that
many of the same variations in climate were present in the past, or are at least comparable. Based on this premise, then, a botanist is able to take a sample
from a tree whose age is not known and compare the rings to a tree whose age is known. By this technique, then, a botanist is able to move further
