GENERAL GEOLOGY

Detailed explanation-1: -200-year anniversary of Jean Louis Rodolphe Agassiz, the founder of the glaciological theory.

Detailed explanation-2: -A glacier is a large, perennial accumulation of crystalline ice, snow, rock, sediment, and often liquid water that originates on land and moves down slope under the influence of its own weight and gravity.

Detailed explanation-3: -What is the structure of a typical glacier? All glaciers, regardless of size, are composed of layers of snow that build up in the upper reaches of an ice mass, become buried, and transform into glacier ice as they are increasingly compressed by the overlying column of snow.
