11/16/17 Unit 4 Review

We were just about to debate the Keystone Pipeline...then tonight this is at the top of the news! https://www.yahoo.com/news/keystone-pipeline-leaks-210k-gallons-230601176.html

is it the mantle that has a partially fluid plastic consistency

nobody knows for sure but both the inner mantle and asnthenosphere (lower upper mantle) have that. Upper upper mantle is solid though

thank you!

can you also explain #30

Can you please ask the question as I do not have the study guide in front of me. Thanks

#25. Describe how this rock formation below originated from a metamorphic rock.

that gets in to rock cycle stories. That is an eroded and weathered sedimentary rock so the granite could have been weathered and eroded, transported down a stream and the sediments cemenetd and compacted...then uplift!

Thanks

Describe 2 specific environmental impacts for each part of the mineral cycle, including extraction, processing, use and discarding

One the last page of the study guide it says "give an example of a specific type of subsurface mining." What would be the answer to that?

Extraction: think of all the things we have talked about with respect to mining (specific water, air, and biosiversity impacts); pracessing: chemicals used get left in tailings bonds which can contaminae groundwater; discarding results in substances going into a landfill and leaching into groundwater or giving off methane depending on the substance

specific type of subsurface mining was from the warm-up diagram and called shaft mining

okay thank you

ayyy

Also, what would be some beneficial impacts of a volcanic eruption?

Volcanic ash is rich in nutrients essential to plant growth

Hey MB do we need to know the magnitude and death tolls for the major earthquakes?

More or less..check out the generalities...check out the PP for details

What is cyanidation?

Thanks!

Cyanidation is the process used to extract gold in heap leaching

Hey all...gotta go. Thanks!

what would be the effects if convective flow in the mantle ceased
