Document Summary

Eae1011 lecture 6 - earth, atmosphere and environment. Earth processes - in, on and above the surface. Surface processes affect the surface and sub surface of the earth. Bedrock = solid rock below the surface of the ground. Regolith = weathered loose fragments of bedrock. Chemical & physical breakdown of rock releases ions/nutrients. Most australian bedrock has been weathering for over 400my, some for up to 3. 7 billion years. Most available nutrients have been used &/or washed out of soil over time. Poor plant cover in deserts = loss of soil in dust storms. What is a fluid, how does it behave?
