GEOGRAPHY 2051 EXAM 2 - NAMIKAS
(LSU) QUESTIONS WITH VERIFIED
SOLUTIONS
Weathering - correct-answer - the breakdown of earth materials into smaller
components
Physical Weathering - correct-answer - involves physical forces (pushing/pulling)
breaking down earth materials
Chemical Weathering - correct-answer - the process that breaks down rock
through molecular changes using water
Parent Material - correct-answer - The original rock or soil type
, 2
Regolith - correct-answer - the substance that parent materials of rocks break
down into before turning into soil
Soil - correct-answer - the result of weathering of rock from parent material to
regolith then to this substance
What are some factors/controls of weathering?
**LOOK AT NOTES** - correct-answer - -Nature of Parent Materials/Rocks
-Climate (moisture levels & temperatures)
-Hydrology
-Topography
-Vegetation
, 3
Jointing & it's effects on rocks - correct-answer - joints are cracks in rocks; they
affect the solubility and rate of weathering in/on rocks
Moh's Hardness Scale - correct-answer - A scale ranking ten minerals from softest
to hardest; used in testing the hardness of minerals
How does climate affect weathering? - correct-answer - Precipitation influences
how strong/weak weathering is, as well as rates
& temperature influences which type of weathering occurs
What type of weathering occurs in hot climates? - correct-answer - Chemical
weathering
What type of weathering occurs in cold climates? - correct-answer - Physical
weathering
, 4
Hydrology - correct-answer - the study of movement of water
How does hydrology affect weathering? - correct-answer - It influences the rates
& strength of weathering
(more exposed to water=higher rate of weathering)
Topography - correct-answer - the shape and physical character of Earth's surface
Microclimate - correct-answer - very small areas in which topography and
hydrology affect vegetation and water movement (which in turn affects
weathering)
