The book presents the cyclicity and micro-cyclicity phenomena which occurred during climate changes and during marine transgressions and regressions. As calculated by the author on the basis of geological research, the climatic cycle of the Earth allows a better understanding of climate changes and associated geological processes in the last 20,000 years. In addition, the author discusses the structure of the sub-Quaternary bedrock and analyses complex geological structures of the Baltic Sea Quaternary deposits. Individual chapters address key aspects of:tectonic and geological analysis of the Baltic Sea basindetailed tectonic and geological analysis of the Polish Baltic Sea and Polish coastal zoneglobal geotectonic cycles of the supercontinentscyclicity and micro-cyclicity arising in the atmosphere and hydrosphere of the Earththe climatic cycle of the Earth, presented for a better understanding of climate changes and associated geological processes in the last 20,000 yearscalculating the extent of the influence of climate change and tectonic movements on marine transgressions and regressionssimulation and correlation of the 310-year climate cyclepredicted future Earth climate cycles in the Northern HemisphereThe book will be useful for students and scientists of marine geology, oceanography, geography and environmental engineering. It will also be of practical utility for all specialists dealing with marine basins and coastal zones, including marine geologists, coastal geologists and geomorphologists, geographers, as well as engineering geologists, geotechnicians and civil engineers. The book is generally related to the discipline of marine geology, and deals directly with the Baltic Sea basin. However, the climate cycle of the Earth, which affects the course of marine transgressions and regressions, has a supra-regional dimension.
