Tree dating activity

Visible rings result from the change in growth speed through the seasons of the year; thus, critical for the title method, one ring generally marks the passage of one year in the life of the tree.Removal of the bark of the tree in a particular area may cause deformation of the rings as the plant overgrows the scar.It also gives data on the timing of events and rates of change in the environment (most prominently climate) and also in wood found in archaeology or works of art and architecture, such as old panel paintings.

Douglass sought to better understand cycles of sunspot activity and reasoned that changes in solar activity would affect climate patterns on earth, which would subsequently be recorded by tree-ring growth patterns (i.e., sunspots → climate → tree rings).

New growth in trees occurs in a layer of cells near the bark.

A tree's growth rate changes in a predictable pattern throughout the year in response to seasonal climate changes, resulting in visible growth rings.

It is clear that dendrochronology is not a clear-cut, objective dating method despite the extravagant claims of some of its advocates.

Extended tree ring chronology is not an independent confirmation/calibration of carbon dating earlier than historically validated dates, as has been claimed.
