GEOL 101 Lecture Notes - Lecture 14: Glacial Landform, Glacier Morphology, Water Cycle
Document Summary
Explain how glaciers are related to the hydrologic and rock cycles. Define glacier and compare and contrast the different types of glaciers. Predict a glacier"s response to the environment. Describe how glaciers erode the surface of the earth. Categorize the different types of glacial landforms. Define the types of materials deposited by glaciers. Explain how glacial and interglacial periods are generated. Water freezes at high latitudes and elevations which contributes to the growth of glaciers. Glacier flow creates friction which generates sediment and breaks rocks into smaller pieces. Glacier: accumulation of snow, ice, and recrystallized snow (firn), lying on land and shows evidence of downslope/outward movement due to gravity. System of moving ice, flows down pre-existing stream valley in mountainous. Occupy broad lowlands at base of mountains. Buries landscape with ice, covering 50,000 square kilometers. System of moving ice that covers a large part of the continent. Glacier budget: balance between accumulation and loss of snow/ice.
