Glacial geomorphology

From GeoClasses

20,000 years ago much of North America and large parts of Eurasia were covered in a thick (over 1 km) layer of ice. Although the ice has melted the landforms left by the glaciers remain, and the Earth itself is still rebounding from effects of these large ice sheets.

Reasons for the Ice Ages

• Paleoclimatic history
• Recent glaciations
  • Glacial history of the last 2 million years
  • Orbital parameters
• Previous glaciations
  • Continental drift and climate

Effects of continental glaciation

• Bearing land bridge
• Glacial rebound
• Continental glacial landforms
