Crust describes the outermost shell of a terrestrial planet. Earth’s crust is relatively thin, just 40-kilometers (25-miles) deep. Earth's crust can be divided into two types: continental and oceanic. How do these two types of crust differ? All BUT ONE could apply. A) Continental crust thicker than oceanic crust. B) Continental crust is less dense than oceanic crust. C) Continental crust granitic composition: oceanic crust basalt and gabbro. D) Continental crust enriched with Fe and Mg: oceanic enriched with Al and Si.

The great scientist alfred wegener proposed that continents have moved, while other scientists such as t. c.chamberlin argued against wegener. wegener's ideas eventually won, and are now widely accepted, because: a) wegener's ideas were more beautiful, and so were favored by the intellectual elite. b) wegener's ideas did a better job of predicting the results of new observations and experiments. c) wegener's ideas appealed to dead white european males, whereas chamberlin's didn't. d) wegener's ideas appalled dead white european males, and we all know that in this politically correct era, dead white european males cannot get a fair shake. e) wegener won the nobel prize.
