Features in parks along san andreas

long mountain ranges, laterally displaced features, rotated mountain ranges, broad zone of shearing

national park on san andreas fault

channel islands

caribbean transform boundary national park

US virgin islands

transverse ranges

uplifted mountains formed where san andreas takes sharp bend

origin of coast range in western california

formed by subduction of ancient farallon plate

origin of sierra nevada in western california

line of volcanoes formed above dehydrating farallon plate

origin of great valley in western california

forearc basin formed between two mountain ranges

franciscan series in western california

sediments and hard crust of ocean floor that were scrapped off the subducting plate

granite batholiths in western california

remains of magma chambers formed beneath volcanoes

how did transform boundary change western california

rocks formed in subduction zone were deformed, rotated, and dragged northward by transform plate boundary

what is tectonic activity associated with in western california

san andreas and other strike-slip faults within transform plate boundary

where do thrust faults occur in western california

where san andreas fault bends, rotating and uplifting the transverse ranges

what is the san francisco bay area

broad zone of deformation from transform boundary

point reyes national seashore

lies on san andreas fault, fault cuts through tomales bay

at what rate does pacific plate move past north american plate?

opposite side moves to the observer’s left

right lateral fault

opposite side moves to the oberver’s right

what type of strike-slip fault is the san andreas fault

right-lateral

what is pinnacles national monument

volcanic terrane transported northward by transform plate motion, made of volcanic breccia

balcones caves

formed where fallen blocks of volcanic breccia formed roofs over large cracks

what type of strike-slip boundary is on us virgin islands

left-lateral

volcanic breccia

coarse-grained rock comprised of angular volcanic fragments

why are the transverse ranges known as a ball-bearing landscape

blocks of crust rotate like ball bearings
