Document Summary
Chapter 1: introduction to physical geology and the environment. 1. 1 william smith father of english geology, first to publish a geological map. 1. 2 william logan first to systematically describe the geology of canada (candian) Cross-section a hypothetical vertical slice thru the land. 1. 3 alfred wegener theo(cid:396)(cid:455) of (cid:272)o(cid:374)ti(cid:374)e(cid:374)tal d(cid:396)ift i(cid:374) (cid:1005)9(cid:1005)(cid:1006) (cid:862)the o(cid:396)igi(cid:374) of co(cid:374)ti(cid:374)e(cid:374)ts a(cid:374)d o(cid:272)ea(cid:374)s(cid:863) Pangea continents has previously been clustered together in a large land mass. 1. 4 j. tuzo wilson plate tectonics theory in the early 1970s (canadian) Transform faults large-scale faults that offset the crust laterally but neither created nor destroyed material, now recognized as a major plate boundary type. Hot spots active volcanoes, young volcanic islands stuck in the middle of the oceans. Volcanic islands chains (ex: hawaiian islands) resulted from a moving plate drifting over a stationary magma plume in the mantle support for plate tectonic theory. Deep time vastly greater amounts of time (more than hours, years)
