ESC 1000 Lecture Notes - Lecture 19: Convergent Boundary, Volcanic Arc, Leading Edge
Document Summary
When the stress is greater than the strength of the rock, the rock will deform in either a __________ or. _____________ brittle ductile fashion synclines folds that have a rough like structure. Anticlines and synclines may be ____________, __________________, ______________, or. Symmetrical, asymmetrical, overturned, recumbent joints fractures in rock that form through brittle deformation. they do not show offsets on either side of the fracture. The offset on a fault may be determined by comparing the blocks of rock on either side of the fault surface. inclination fault"s dip. Most orogenesis occurs along convergent plate boundaries, where compressional forces cause folding and faulting of the rock, thickening the crust_______ while shortening it ___________________. vertically and horizontally. If a subducted plate is over-ridden by oceanic lithosphere, island arc-type mountain building results -- a thick accumulation of erupted volcanic rocks mixed with sediment scrapped off the subducted plate.
