8.3 Climate Change Flashcards
(12 cards)
Cause of ocean acidification
burning fossil fuels
Ocean acidification makes the ocean more
acidic
What particular ecosystem is ocean acidification detrimental for
coral reefs because they need carbonate to calcify –> this affects diversity in the ocean bc coral is super important
Ocean Acidification (chemically)
CO2 is absorbed by the ocean and it reacts with hydrogen to form carbonic acid
The carbonic acid decomposes into Hydrogen and bicarbonate
the hydrogen reacts with the carbonate and forms bicarbonate ion, so the carbonate ion decreases because there’s more hydrogen
albedo
earths reflectivity effect
what is albedo (what it does)
basically the phenomena that snow and ice reflect a lot of the suns rays back into space so the earth does not get too hot
what is the effect of climate change on albedo
its reducing its effect and therefore the earth is getting hotter bc theres not a lot of snow and there’s more water and the water absorbs the heat and melts the snow and then it becomes a cycle
why is the melting of permafrost bad
they release microbes
they release carbon
lake holes
why is the increase in microbes bc of melting permafrost bad
they release carbon dioxide and methane which are greenhouse gasses
why is the melting of permafrost (carbon thing) bad
bc permafrost holds almost 3x more carbon than even forets
what is a worse greenhouse gas methane of co2
methane
why are lake holes caused by permafrost bad
they release sm methane you light some on fire and the land also does mudslides and stuff like that bc only permafrost was holding the together
