Glacial Budget and Movement Concepts

The video tutorial explains glaciers, their movement, and the processes of accumulation and ablation. It covers the zones of accumulation and ablation, the concept of glacial budget, and the effects of positive and negative budgets on glacier size. The snout of a glacier is also defined.

What causes glaciers to move?

• Earthquakes

• Tides

• Gravity

• Wind

What is the process called when snow and ice are added to a glacier?

• Accumulation

• Condensation

• Sublimation

• Erosion

Which part of the glacier experiences more melting than snow accumulation?

• Zone of Accumulation

• Zone of Ablation

• Snout

• Crevasse

What is the term for the difference between total accumulation and total ablation in a year?

• Glacial Retreat

• Glacial Mass

• Glacial Budget

• Glacial Flow

What happens to a glacier with a positive glacial budget?

• It melts completely

• It remains the same size

• It splits into smaller glaciers

• It grows larger and advances

What is the result of a negative glacial budget?

• The glacier stays the same

• The glacier retreats

• The glacier forms a new snout

• The glacier expands

What is the term for the bottom end of a glacier?

• Peak

• Snout

• Crest

• Base
