Webb10 maj 2024 · Many scientists believe that during these two particular periods, the entire earth was covered in ice. A differing theory, however, suggests that an area of ocean located near the equator was left only partly frozen. The academic community has still not reached an agreement about how the Cryogenian Ice Age came to pass. Webb23 aug. 2013 · As the ice spread, more heat was reflected back into space rather than absorbed by the planet, dropping temperatures down in a runaway effect that sped the formation of ice.
