LUOA Earth Science Module 8 Questions and Answers Graded A Glossopteris was a temperate climate leaf fossil. He found it in Antarctica. How could this be? Because that fossil was supposed to have been in a temperate climate near the equator but instead was in Antartica, meaning that the continents have moved since the beginning of time. Alfred Wegener discovered rocks in the Appalachian Mountains matched rocks in _______________________. Europe and Greenland Originally, Wegener's hypothesis ...

superposition - The principle that any given rock layer is probably older than those above it and younger than those below it continental crust - Extends from surface of Earth down to 20-30 miles. Continental crust (granite) is less dense then ocean crust (basalt). oceanic crust - Extends down from the surface of the Earth to 7 miles. Crust is layered and very uniform. Composed of basalt. mantle - Contains most of Earth's mass. Composed of iron, magnesium, aluminum, and siliconoxygen comp...
