material to regolith then to this substance
,Geography 2051 Exam 2 - Namikas (LSU)
Questions And Answers
What are some factors/controls of weathering?
**LOOK AT NOTES** -
correct answer ✅-Nature of Parent Materials/Rocks
-Climate (moisture levels & temperatures)
-Hydrology
-Topography
-Vegetation
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
