  Quaternary Geology
The Quaternary period is subdivided into the Pleistocene (“Ice Age”) and the Holocene (present warm interval) epochs, with the Pleistocene spanning most of the Quaternary and the Holocene covering the past 10 000 years.
The Quaternary period is characterized by a series of large-scale environmental changes that have profoundly affected and shaped both landscapes and life on Earth.
One of the most distinctive features of the Quaternary has been the periodic build-up of major continental ice sheets and mountain ice caps in many parts of the world during long lasting glacial stages, divided by warm episodes (interglacials) of shorter duration, when temperatures were similar to or higher than today.

 ISGS - Glacial Geology
Glacial geology is important in Illinois' most recent geologic past, the Quaternary Period (also called the Ice Age), during which continental glaciers repeatedly plowed across the state eroding and redistributing material and creating new landforms.
Today, Illinois is experiencing an interglacial episode, a relatively quiescent and warm interval of the Quaternary Period that allows the soil to form and crops to grow.

The Earth's youngest period, the Quaternary, includes the last 2–3 million years and is characterized by several glaciations and warmer interglacial intervals.
The cause of the climatic changes is probably to be found in the Earth's orbital parameters, which result in lower summer insolation in the northern hemisphere, which in turn leads to glaciations.
Thus, the Quaternary deposits of Sweden are very young compared to those in non-glaciated areas.
