Outgassing Study guides, Class notes & Summaries

How Old are the oceans - 4 billion years How were atmospheres and oceans formed - outgassing and icy commets what is outgassing - when volcanoes erupt and water vapor is condensed and turned into clouds and rain What are the internal Layers of earth - lithosphere asthenosphere mesosphere outer core inner core Lithosphere - Crust and Upper Mantle Asthenosphere - upper mantle (below lithosphere) Mesosphere - Rest of Mantle Outer core and inner core - outer fluid inner so...

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...

Origin of Earth, Oceans, Life: • Earth: Supernova (explosion of a star-4.6 bya)- earth (nebula made of gas and dust) was formed 4.5 billion years ago. • Oceans: Volcanic expulsion, rained for thousands of years then hit by icy comets; volcanic outgassing and ice from comets • Life: 3.7 billion years ago life was created- animals have been arou...

Carbon Cycle -Answer Largest Carbon Store = Lithosphere/ Sedimentary (100,000,000 PgC) Largest yearly flux = Photosynthesis (103 PgC from Atmosphere 560 to Biosphere 2,060) Smallest Carbon Store = Atmosphere/ Plants (both 560 PgC) Smallest yearly flux = Sedimentation/ fossilisation (0.2 PgC from Deep Oceans 38,000 to Fossil Fuels 4,000) Geological carbon formation -Answer 1. Coal = duration and heat intensity influences %C 2. Limestone = compaction/cementing of shells 3. Crude Oil =...
