Many Geologists Have Concluded That the Development of Ice Ages

Many geologists have concluded that the development of ice ages requires:

A) all of the Earth's continents to mass together near the poles, and dramatic shifting of the climatic belts.
B) relatively high- elevation landmasses near the equator and relatively low- elevation landmasses near the poles.
C) sizable landmasses near the poles, and land surfaces with relatively high elevation.
D) massive amounts of near polar waters, and an increased distance between the Earth and the Sun.
