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...

LUOA Earth Science Module 8 Questions and Answers Graded A Pangaea mean all the earth Alfred Wagoner found what in Africa,India,South America and Australia that showed him they were all covered in ice at some point ice striations why didn't scientist in 1912 take Alfred seriously? because there was no way the continents could plow through the ocean basin because they didn't know of a strong enough power because he wasn't a geologist Alfred Wegener proposed his idea of continental drift whi...

hypothesis - proposed explanation for an observed phenomenon, which can be rigorously tested using the scientific method (may be regarded as a prediction) theory - supported by a number of testable statements and used as a general principle to explain a phenomenon; intended to be accurate. predictive models of the natural world Theory of Plate Tectonics - proposed explanation by Alfred Wegener of the formation of the continents first as a Pangaea supercontinent then Laurasia and Gondwanalan...

Geology Exam #1 Questions With Answers Who proposed the theory of Continental Drift? Alfred Wegener. In which ocean are most of the world's convergent plate boundaries located? Pacific Ocean. The east coast of North America is a what boundary? The West coast of South America is what boundary? Not a plate boundary. A convergent plate boundary. What is associated with a divergent plate boundary? Name a divergent plate boundary. Earthquakes, volcanicm and rifting. The mid-at...

Conservative plate boundary - Answer where two tectonic plates slide past each other convergent plate boundary - Answer plates move towards each other and collide Divergent plate boundary - Answer Plates move away from each other Alfred Wegener 1912 - Answer All continents were once joined in a super continent called Pangea. Continental drift caused Pangea to move apart Holmes 1929 - Answer Convection in the mantle is the force behind continental drift oceanographic vessels 1...
