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...
