Glaciation is the forming of ice (glaciers) on land. It is related to the Milankovich theory.
Causes of glaciation
- A temperature decrease about 4-5o C around the world
- Higher amounts of snow near the Arctic
- The difference of the Earth's orbit from a perfect circle
- Changes in Earth's axial tilt

Glacial and interglacial cycles as represented by atmospheric CO2, measured from ice core samples going back 800,000 years. The stage names are part of the North American and the European Alpine subdivisions. The correlation between both subdivisions is tentative.
