What can you conclude about the climate in the Neoproterozoic? What will be an ideal response?
Because there was extensive glaciation, and glaciers seem to have been present even at
equatorial regions, it is safe to assume that the Earth was a fairly cold, inhospitable place.
Widespread tillites, of about the same age, provide evidence of this glacial event. However,
glaciation was not continuous, but episodic, so there may have been times between
glaciations when the climate moderated
