Glaciation is the forming of ice (glaciers) on land.[1] It is related to the Milankovich theory.[2]

Causes of glaciation[change | change source]

  • A temperature decrease about 4-5o C around the world[1]
  • Higher amounts of snow near the Arctic[1]
  • The difference of the Earth's orbit from a perfect circle[3]
  • Changes in Earth's axial tilt[3]
