jégkorszaki

Jégkorszaki refers to the geological periods known as ice ages, characterized by prolonged periods of global cooling and the widespread presence of glaciers and ice sheets. Earth has experienced several ice ages throughout its history, with the most recent one being the Quaternary glaciation, which began about 2.6 million years ago and continues to the present day, though it is currently in an interglacial phase. During glacial periods within this epoch, massive ice sheets advanced across continents, significantly altering landscapes through erosion and deposition.

The term "jégkorszaki" is often used to describe phenomena, artifacts, or biological remains dating from these glacial periods. For example, jégkorszaki mammals include animals like the woolly mammoth, saber-toothed cat, and cave bear, which were adapted to the cold environments of the time. Jégkorszaki artifacts might refer to stone tools or cave paintings created by early humans who lived during these eras. The study of jégkorszaki deposits, such as moraines and outwash plains, provides crucial evidence for understanding past climate change and the extent of glaciation. Scientists reconstruct past climates using various proxies, including ice cores, sediment layers, and fossil records, to learn more about the conditions and life forms of the jégkorszaki periods.
