Abstract | Climatic cycles are studied by investigating geological phenomena, shown by terraces around lakes and seashore, paired beds of rock formations and differing materials. The various geological periods and sub-periods are divided on climatic changes. These geologic periods are studied to obtain the effects of climate. The cycles are computed by geometric progression series, assuming that the cycles are harmonic. Geologic formations are pictured and 1 cycle graph is shown with tables of triple progression cycles showing length of time. These cycles extend much further back in history than the tree ring cycles. |
