I want to know the answer to the following question:
Compared to the Ordovician glaciation, how big were the ice caps on Gondwana during the Silurian?
All the background I'm provided with is that "The melting of ice caps and glaciers contributed to a rise in sea levels, recognizable from the fact that Silurian sediments overlie eroded Ordovician sediments, forming an unconformity.". Is that enough to answer the question?
