Movements of Earth's tectonic plates can affect long-term climate and create geographic barriers that can have local climate effects, but they do not directly affect climatic variations and advances and retreats of ice sheets during the Pleistocene epoch. Variations in the Sun's energy output, wobbling of Earth's rotational axis, and precession of Earth's orbit are all factors that can significantly affect these climatic variations.
