Study Notes
Geomorphology and Glaciers
- The zone of illuviation refers to the recrystallization of minerals or deposition of fine materials that occurs directly below the zone of eluviation.
- A landscape consisting of overlapping alluvial fans along a mountain front is called a bajada.
Deserts and Atmospheric Circulation
- The Sahara Desert in Africa is best associated with the descending air of the subtropical high-pressure cell of the three-cell model of atmospheric circulation.
Aeolian Sediment Transport
- Saltation is an aeolian sediment transport process that requires the sediment to remain in contact with the surface at all times.
Cultural Revolution of Agriculture
- The cultural revolution of agriculture (horticulture) began around 10,000 years ago.
Glaciers and Meltwater
- When meltwater accumulates at the base of a glacier, providing a lubricant between the underlying rock and the glacier, the glacier moves through the process called basal sliding.
Glacial Formation and Composition
- After the transition from snow to firn, additional compaction results in more air being squeezed out, resulting in a dense material with ice crystals aligned to each other, making up approximately 90% of the solid mass.
- The gradual thickening, compaction, and recrystallization of snow and water over time form a feature called ice.
- The part of the glacier where snow melts is called the ablation zone.
- Freshly fallen snow is roughly 20% air.
