Why study global change? - Answer--allows us to understand why global temps fluctuate and what causes fluctuations (natural and anthropogenic) -how it affects populations over time -tackling climate change before it things get much worse Why does the Earth change - Answer-1-earth's internal heat makes the asthenosphere weak enough to flow 2-Sun radiation What happens as a result of a weak asthenosphere? - Answer--continental drift -volcanism: enough volcanic outgassing can cause clim...

A) His English was too poor to understand by them B)He couldn't provide a valid mechanism that would cause continents to shift positions C)he had little evidence supporting the existence of the super contin...

ESS 101 INTRO TO GEOLOGY - University of Washington_ Laboratory 5A : Sedimentary Rock FormationScore for this attempt: 8.9 out of 10 Introduction In the igneous rock lab, we focused on tectonic proce sses that influence rock formation inside of the earth’s crust. Now we will turn to the earth’s surface, where rock weathers into smaller rock fragments and minerals. The solid particles and dissolved ions (charged atoms and molecules) freed by weathering processes are transported by water, wind...

The process of unloading can produce: (a) joints (b) mud cracks (c) pillows (d) cross-bedding (e) leaching - a An unconformity, like the one in the Kingston area, is best defined as: (a) a layer of rocks with very unusual fossils (b) a basal conglomerate (c) a layer of sedimentary rocks (d) a thin, tabular or sheet-like, igneous intrusion (e) a time gap in the rock record - e Weathering produces minerals that are more stable at the Earth's surface. Of the five minerals listed below...

Geology 1114 Test 1 Exam Questions And Answers (Verified And Updated) Flux melting most likely occurs at: (A) Mid-ocean ridges. (B) Transform faults. (C) Subduction zones. (D) None of the above - answer(C) Subduction zones. Decompression melting occurs as a result of: (A) Decrease of the confining pressure as the Core rises to shallower depth. (B) Increase of the confining pressure as the asthenosphere rises to shallower depth. (C) Decrease of the confining pressure as the lithosphere ...
