Pleistocene & Holocene Epochs | GEO GIRL The Pleistocene and Holocene epochs represent the most recent chapters of Earth's history, spanning the last 2.6 million years within the Quaternary period. • YouTube • ANTHRON....<


The Pleistocene Epoch (2.6 Million to 11,700 Years Ago)


• The Ice Age: Characterized by cyclic glacial and interglacial periods where massive ice sheets covered large parts of the Northern Hemisphere. • YouTube •GEO GIRL +1


• Climate Drivers: Driven by Milankovitch cycles, which involve changes in Earth's eccentricity, axial tilt, and precession. oClimate Drivers: Driven by Milankovitch cycles, which involve changes in Earth's eccentricity, axial tilt, and precession. o • Megafauna: Home to iconic large mammals like woolly mammoths, saber-toothed cats, and giant ground sloths. c Class Central • Human Evolution: Marked by the evolution and early migration of the genus Homo, including Neanderthals and modern humans (Homo sapiens). • YouTube • ANTHRON... The Transition and the Holocene Epoch (11,700 Years Ago to Present) • Warming and Retreat: Marked by the end of the last major ice age, rising sea levels, and retreating continental glaciers that carved out modern landscapes like the Great Lakes.


• Human Civilization: Provides a warm, stable interglacial climate that allowed agriculture, writing, permanent settlements, and all recorded human history to flourish. *


• Modern Impact: Human activity has drivenHuman Civilization: Provides a warm, stable interglacial climate that allowed agriculture, writing, permanent settlements, and all recorded human history to flourish. • Modern Impact: Human activity has driven major environmental changes, leading scientists to debate whether we have entered a new epoch called the Anthropocene. You can watch an in-depth breakdown of these two time periods in the Pleistocene & Holocene Epochs video by GEO GIRL.
