1.2C Chile con Carnage

Question 1

What happens at the Benioff Zone?

Answer 1

crystal rocks melt with various chemical reaction

Question 2

True or False?

Basaltic oceanic crust is denser, so it subducts, teating and defomaing so it becomes quite unstable
mantle that forces its way to the surface.

Answer 2

True

Question 3

What stresses can encourage a landslide?

Answer 3

Angle of slope
Rainwater
Vibration 
Earthquakes 
Sea, Cliff erosion

Question 4

Give examples of strengths, to help reduce chances of landslides

Answer 4

Lubricant layers
Vegetation
Consolidation of material
Porosity of soil

Question 5

Change the focal depth what happens to magnitude?

Answer 5

creates higher moment magnitude

Question 6

If you make the slope (mountain etc) higher then you likely to increase the chances of what?

Answer 6

avalanches / freeze-thaw rock breakdown will be higher

Question 7

What happens if there is higher mountain uplift

Answer 7

more like to have precipitation

Question 8

Add more hydration melting – get more explosive, andesitic lava. Is that strength or stress?

Answer 8

Strength

Question 9

What is hydration melting?

Answer 9

water involved lowers the melting temperature

Question 10

Continental crust is denser, so it subducts, teating and defomaing so it becomes quite unstable mantle that forces its way to the surface.

True or false ?

Answer 10

False

Basaltic oceanic crust is denser, so it subducts, teating and defomaing so it becomes quite unstable mantle that forces its way to the surface.
