Climate Change Flashcards
[Ocean Acidification]
What does climate change cause?
(5 causes)
-Ice sheets
-Glaciers to melt
-Sea level Rises
-Change in weather pattern
-Drought and flooding
[Ocean Acidification]
What does carbon dioxide do to our oceans?
Change the chemistry
[Ocean Acidification]
How much carbon dixoide absorbed by the ocean is from human realese in the atmosphere
1/4
[Ocean Acidification]
co2=
series of chemical reactions occurs
the increased concentration of hydrogen ions
[Ocean Acidification]
What does CO2 cause
- makes water more acidific
-cause carbonate ions
[Ocean Acidification] what happens when decrease in carbonate ions?
-affect the building of shells and calcium carbonate structures difficult
[Ocean Acidification]
What does
pH of 7=
pH of 7> =
pH of 7< =
- neutral
-Acidic solution
-Basic solution
What is CO2 made by :
-Combustion reaction
-Cellular respiration
What causes CO2 to increase?
- Humans by combustion of fossil fuels
What is Fossil Fuels?
Made from decomposed plant or animal material from long ago trapped in the earth. and better when burned
What can fossil fuels be used for?
-Energy production
-Transportation
-Heating
-Making plastics
-Cooking
-Agriculture
-Construction
-Steel-making
-No reason
[Acid Rain]
what is the pH of normal rain?
5.6
[Acid Rain]
Whats the pH of Acid Rain
2 or 4.6
[Acid Rain]
Why is fossil fuel dangerous
when combined w water and oxygene, it can produce sulphuric, nitric, nitrous acids
[Acid Rain]
What two deposition can acids have
wet or dry
[Acid Rain]
What is the effect of Acid Rain on materials
- Damage material need to be repair
-loses detail
[Acid Rain]
What is the effect of Acid Rain on Ecosysteme
-flows through soil causes leach aluminum
-some plants can tolerant but some cant when pH declines
[Acid Rain]
What is the effect of Acid Rain on Fish/Wildlife
-ph of 5, fishes cant hatch
-Lower pH some adult fishes die
-Affects food chain as a certain species can tolerate while the rest cant
[Acid Rain]
What is the effect of Acid Rain on Plant
-Dead trees
-Strips nutrient from trees
[Acid Rain]
What is the effect of Acid Rain on Health
-Not dangerous
-unless you have lung conditions
