1b.Physical Factors

Question 1

Climate

Answer 1

• Wind: carries out erosion, transportation, deposition
• Precipitation: snow, sleet, rain (low in high latitude areas)
• Temperature: High altitude areas experience long periods of 0< summer temps

Question 2

Geology - Lithology

Answer 2

• Physical & chemical compositions

- Weak lithology = little resistance (will be weathered / eroded)

Question 3

Geology - Structure

Answer 3

• Properties of individual rock: jointing, bedding, permeability (porous rocks - absorb water)
• Also includes angles of rock

Question 4

Latitude & Altitude

Answer 4

• High latitude: cold, dry, little seasonal variation, less melting, large ice sheets
• Low latitude: warmer, more accumulation, more melting, more seasonal variation
• High altitude: cold, some glaciers can be located near equator

Question 5

Relief and Aspect

Answer 5

• Steeper relief of landscape = more resultant of gravity down slope
• Aspect away from sun = longer periods of below 0 temps (positive mas balance)

Question 6

Other Physical factors

Answer 6

• Ice formation (snow into ice)
• Meltwater
• Deposition
• Glacial movement (how far glacier grows)
