Climate changes originating from changes in the Earth's orbit and changes in its axial inclination are proposed as causes of glaciations according to Esmark, in an article published in 1824. There are three important types of statement for the ice ages i.e.; chemical, geological and paleontological. geological; this Ice Age evidence comes in different forms, involving stone scraping and scouring, valley cutting, drumlins, glacial moraines, ice erratics, and land deposition. Consecutive glaciations tend to deform and erase geological evidence, thus creating difficulties of interpretation (Peltier) The paleontological; this evidence includes the geographic distribution of residual changes. Again it is difficult to interpret as it requires a series of sediments covering a very long period, the range of latitudes, ancient organisms which survive unchanged for a few million years and whose temperatures can be rapidly diagnosed and the related fossil findings. Chemical tests; mainly includes variations in isotopic ratios in fossils found in sedimentary and sedimentary rocks and in the bases of ocean sediments. However, this evidence may be contradicted by other influences shown by other isotopes
