Document Summary

James hutton speculated that the formation of rocks and landscapes were a consequence of processes that could be observed; this notion came to be known as uniformitarianism. Hutton deduced that the formation of geological features took a long time, and that not all features formed at the same time. Hutto(cid:374) also sur(cid:373)ised that the earth"s pro(cid:272)esses (cid:373)ust ha(cid:448)e (cid:271)ee(cid:374) a(cid:272)ti(cid:448)e a lo(cid:374)g ti(cid:373)e (cid:271)efore human history began. Physical processes that operate in the modern world also operated in the past at roughly comparable rates, and these processes were responsible for forming geologic features preserved in outcrops; (cid:862)the past is the ke(cid:455) to the prese(cid:374)t a(cid:374)d future(cid:863) The continents look like they might fit together. All late paleozoic glaciated areas lie adjacent to each other when the continents are connected to form pangaea. Distribution of fossil species requires the continents to be adjacent to one another.
