Natural cycles are periodic or quasi- periodic processes that influence Earth 's climate through gh variations in solar energy received, heat distribution across the planet, and the composition of the the atmousphere. They arise from the planet' s orbital geometry, its internal nal heat engine, solar variability, and the complex interplay betweene them atmouste, oceans, and land surfaces.
