GLACIOLOGY Crossword Puzzle

QUESTIONS LIST:

• glacier : a large persistent body of ice that forms where the accumulation of snow exceeds its ablation (melting and sublimation) over many years, resulting in the movement of ice downhill under the force of gravity.
• ice sheet : a mass of glacial ice that covers surrounding terrain and is greater than 50,000 square kilometers in area, usually found in polar regions.
• ice cap : a smaller ice sheet, typically covering less than 50,000 square kilometers, often found on mountaintops or in polar regions.
• iceberg : a large piece of freshwater ice that has broken off from a glacier or ice shelf and is floating freely in open water.
• ice shelf : a floating platform of ice that extends from a land-based glacier into the sea, formed by the advance of a glacier into the ocean.
• ice field : an extensive area of interconnected glaciers covering a mountain range or other topographical feature.
• moraine : accumulation of rock and sediment carried or deposited by a glacier, often forming ridges or mounds.
• crevasse : a deep crack in the surface of a glacier, formed as a result of the glacier's movement over irregular terrain.
• firn : compacted granular snow that forms over time as successive layers of snow are buried and compressed under their own weight.
• glacier retreat : the process by which a glacier's terminus (front) moves back due to melting and calving, often as a result of climate change.
• glacier advance : the process by which a glacier's terminus advances forward due to increased snowfall or decreased melting.
• glacier surge : a temporary and rapid advance of a glacier, often characterized by sudden movement and increased flow rates.
• glacier dynamics : the study of the movement, behavior, and internal deformation of glaciers, including factors such as flow rates, crevasse formation, and basal sliding.
• glacier erosion : the process by which glaciers sculpt and shape the landscape through the abrasion and plucking of rock and sediment.
• glacier lake : a body of water formed by the melting of ice or damming by glacial moraines, often found at the terminus of a glacier.
