LUOA Earth Science Module 8 Questions and Answers 100% Pass 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 wh...

EARTH SCIENCE FINAL EXAM QUESTIONS AND ANSWERS ALREADY PASSED What are the three primary layers of Earth, arranged from the center to the exterior, based on their composition? 1) Core - Comprising both a solid inner core and a liquid outer core, this layer consists mainly of an iron-nickel alloy and is under immense pressure. 2) Mantle - Occupying 82% of Earth’s volume, it is a solid, rocky layer surrounding the core. 3) Crust - The outermost layer, with oceanic crust featuring ...

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 ...

List the 3 main layers of the earth from the center to the outside based on composition (what they are made out of). - Answer-1). Core (Inner and outer)-solid inner liquide outer. Iron/nickel alloy. Extreme pressure 2).Mantle-82% of the earth's volume-Solid, rocky, shell 3). Crust (Oceanic-younger rocks and Continental-granite rocks) List the 5 mechanical layers of the earth (based on how they deform?) Whic layers is a liquid? - Answer-1.The lithosphere is the outermost mechanical layer a...

What are the layers of the Earth? Ans: Crust, Lithosphere, Asthenosphere, Mantle, Outer Core, Inner Core What are three plate boundaries? Explain/Give Example Ans: Divergent - Push Away/Mid-Atlantic Ridge Convergent - Pull Together/Himalayan Mountains Transform - Slide Past/San Andreas Fault Who created the continental drift theory? Ans: Alfred Wegener in 1915 How long ago was Pangea present? Ans: 225 Million Years ago What animal fossil was used to support continental drift? Ans: Mes...

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...

Mttc Integrated Science (Earth And Space Sciences) Elaborated Questions And Answers Theory of Plate Tectonics - CORRECT ANSWER-A theory stating that Earth's lithosphere is broken into huge plates that move and change in size over time - explains the process of continental drift - theory is a fusion on the theories of continental drift and seafloor spreading - continents are not floating on the ocean, rather they are rooted What are the 10 major plates of the Earth's lithosphere? - C...

Continental Drift - Answer-A theory supporting the possibility that continents are able to move over Earth's surface Plate tectonics - Answer-the process where large sections (plates) of the Earth's crust are in constant movement over the fluid mantle, causing earthquakes and volcanoes at the borders between the plates Lithosphere - Answer-The outermost layer of the Earth's crust Asthenosphere - Answer-a nearly liquid layer made of the uppermost part of the mantle Mantle - Answer-...
