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...

ESS 101 INTRO TO GEOLOGY - University of Washington_ Laboratory 5A : Sedimentary Rock Formation. Fall 2022. Score for this attempt: 9.5 out of 10 In the igneous rock lab, we focused on tectonic proces ses 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...
