Your answer is; data storage problems
The accretionary wedge is like the accretionary prism and the definition of that is : *a mass of sedimentary material scraped off a region of oceanic crust during subduction and piled up at the edge of the overriding plate (source : dictionary)* and the formation is when two plates crash and one slides under the other one I believe and sand ad sediment go into the little open space between them that give you a wedge. Hope I helped.
Lower population and thus lower conflict
sec(A) = 5/3 ⇒ cos(A) = 3/5
Angles A and C are complimentary (they sum to 90°), so
sin(C) = cos(A) = 3/5
since sin(90° - x) = cos(x) for all x, and in turn
csc(C) = 1/sin(C) = 5/3
Convection currents are vertical circular movements of fluids that transfer energy due to changes in density.
