Glacial-interglacial cycles refer to the natural fluctuations in Earth's climate that lead to periods of glacial expansion and retreat, significantly influencing global temperatures and sea levels. These cycles are driven by factors such as changes in Earth's orbit, solar radiation, and greenhouse gas concentrations, which play a crucial role in shaping landscapes and ecosystems over thousands of years.
