Ice Ages

~1800 answered questions
Parent Category: Geology
Caused by long periods of reduced atmospheric and surface temperature, widespread continental glaciation and cooling are called Ice Ages or Glacial Ages. Questions about the most recent and current geologic period, the Quaternary, and other ice ages are what this category is all about.
The Pleistocene Epoch was from about 1.8 million to 11,000 years ago. The word means "nearly present" or "most new" in Greek. It is marked by the ice ages and the emergence of the human species.

The Quaternary is the most recent geological time period, which started 1.67 to 2.4 million years ago depending on the area studied. The Quaternary is part of the Cenozoic ("new life") Era, along with the Tertiary Period. The Quaternary Period includes recent time (the last 11,000 years ago, since t…

you should specify which ice age; there have been hundreds. As far as why, that is a great question, and I don't think anyone has the answer. Ice ages are tied pretty close with atmospheric carbon dioxide levels. Carbon dioxide, you have probably heard, is a greenhouse gas, meaning it traps heat on …

Glaciation is a single event occurring in an ice-age period. We are currently in an ice age in earth history, but not currently in a period of glaciation. An interglacial period of moderate temperatures. More glacial episodes are expected to occur in the future.

There have been several ice ages in the past; the most recent true major ice age started in the Pleistocene epoch 1.6 million years ago. However, it also depends upon one's definition of "ice age". Scientists cannot seem to agree on the answer to this. A mini-ice age is believed to have occurred dur…

The last Ice Age hasn't ended, as evidenced by the fact that glaciers are still on the planet. We are currently in an interglacial period within the current current Ice Age.The term "ice age" is colloquially applied to a period of maximum glaciation, the last of which occurred 20,000 years ago.

About 20,000 years ago. I read it off of Wikipedia. There have been many ice ages over the past 2.4 billion years. The present ice age started about 2.6 million years ago although there have been many warm periods,(interglacials), during that time, we are in one now.

No one is certain why the mammoth became extinct. They died. They may have succumb to climate change at the end of the last Ice Age. Other theories are related to the arrival of modern humans, which may have spread diseases that were fatal to mammoths, or over-hunted them.
