21 sie 2024 · A glaciation (or ice age) occurs when the Earth’s climate becomes cold enough that continental ice sheets expand, covering large areas of land. Four major, well-documented glaciations have occurred in Earth’s history: one during the Archean-early Proterozoic Eon, ~2.5 billion years ago; another in late Proterozoic Eon, ~700 million years ...
Abstract. The ‘glacial theory’ championed by Louis Agassiz in the 19th century saw the beginning of the geological community’s partial acceptance of the concept of multiple and more extensive glaciations. Formal recognition of multiple glaciations came in 1909 with Penck and Brückner’s Alpine model. Since then, research on the Earth ...
