Question

multiple-choice question how many different glacial maxima have there been in the last million years? 9 11 10 8

Explanation:

To determine the number of glacial maxima in the last million years, we refer to geological and climate science knowledge. Over the last million years (the Quaternary glaciation, particularly the Pleistocene epoch), the glacial - interglacial cycles have been studied extensively. The Milankovitch cycles (variations in Earth's orbit, axial tilt, and precession) drive these cycles. Based on scientific research, there have been approximately 10 glacial maxima in the last million years.

Answer:

10 (the option with "10" should be selected)
