Building Mountains Cheat Sheet (DRAFT) by roobear

Conver­gence of oceanic plate and contin­ental plate with leading edge resulting in subduc­tion, contin­ental volcanic arc, and compre­ssional features. The accret­ionary wedge grows as sediments are scraped from the subducting plate and accreted against contin­ental block

Folds - a response to compre­ssive stress
  Anticline - upward fold (hill)
  Syncline - downward fold (valley)
Faults fracture in the crust involving displa­cement of rock
  Normal faults - stretching and thinning
  (longer valleys, lower hills)
  Reverse faults - shortening and
  thickening (steeper hills and valleys)
  Transform fault - lateral shift
  (diverging in opposite directions
  horizo­ntally)

Conver­gence of two oceanic plates forming an island volcanic arc, building units of contin­ental crust. Arc shape is the result of convex curvature of subducting plate under compre­ssion

Orogeny occurs when plate motion compresses the plate margin causing the plate to crumple and uplift to form mountain range(s). Two lithos­pheric plates carrying contin­ental crust collide then the crust fuses and thickens.
