Document Summary

Most of the evidence at the time was from the. Southern hemisphere, and that is where the few supporters of the concept of continental drift were located: their evidence (see especially fig. 1(cid:895) re(cid:373)arka(cid:271)le (cid:858)fit(cid:859) of the (cid:272)o(cid:374)ti(cid:374)e(cid:374)ts, espe(cid:272)iall(cid:455) east outh a(cid:373)eri(cid:272)a a(cid:374)d (cid:449)est afri(cid:272)a: fossil distribution: distributions of late paleozoic and early mesozoic fossils through south.

Ocean crust gets progressively older away from the mid-ocean ridge: new field of paleomagnetics used magnetic directions recorded in rocks to determine the latitude at which the rocks were formed. 3. 2: most mountain belts form where plates collide.
