weathering and erosion

Alude A

the types of physical

frost wedging, salt expansion, thermal expansion, water movment, root wedging,

list chem weathering?

Dissolution, oxidation, hydrolysis, hydration

How do joints (fractures) affect weathering? 

more surface area for exposure

A rock with joints would weather faster than a rock with no joints.  Why is this true?

cause of structral integrity, allows for roots to grow, water to seep, and more surfice area for exposure

  What is differential weathering?

softy weak rocks weather faster then hard strong rocks

How does surface area affect weathering?

exposure to water, O, chem, and microbes

What is a weathering rind?

The “Skin” that falls of the og rock (chemically)

exfoliation?

“skin” that also falls of (physically)

Are all rocks equally susceptible to weathering

hell yea

What is regolith?

layer of loose broken rock
