Dendroclimatology and dendrochronology are names given to these fields of research. Traditionally, progress rings (also called advancement increments) had been named once-a-year rings. Present day idea of seasonal wood formation now recognizes that many trees, notably within the tropics and subtropics, form rings not on an yearly foundation but relatively in reaction to numerous cyclic environmental ailments. Growth rings are visible because of the dissimilarities in cell forms, qualities, and arrangement amongst these cycles.
