How many Ice-Ages have occurred in the history of the world. Including major and non-major?

Question

I know there has been 4 major Ice-Ages, but what about Minor included?

Answer 1

Yes - interesting these last million and a half years with the Ice Ages.  I don' t think anybody knows for sure what you ask.  

The problem is that each Ice Age tends to s***w up the evidence for the one before.  So I think geologists sort of figure there were the big 4 - but as for minor ones, there were probably hundreds - hope we're not going into one right now.

Answer 2

In the past one million years, Major Ice Ages have been occurring about every 100,000 years and minor ice ages called " little ice ages " could have a 20,000 to 40,000 year cycle.

Answer 3

I wish I could tell you...but I don't know.

I do know that in Pennsylvania, at Hickory Run State Park there is a HUGE boulder field that is amazing to see.

They show you how it was formed from the ice age and other processes. If you are ever around, CHECK IT OUT!

Have a great day!
