Why is ocean acidification a problem for animals that build their shells out of carbonate?

Lower pH lowers the amount of carbonate avaliable for use

Why do continents warm faster than oceans?

Low specific heat so they release energy faster than H2O

How warm does the SST need to get for the corals to experience thermal stress?

1° warmer than the max summer temperature for that area

Which of the following is the most concentrated source of CO2 in the atmosphere?

Exhaust from combustion of organic materials

What is the reason for the seasonal up and down pattern each year. Show on the Keeling Curve.

CO2 in the summer decreases due to photosynthesis

For a given atmospheric CO2 level, why does the pH stay higher when the temp is higher?

Warmer water will absorb less atmospheric CO2

Why does high temperature cause corals to bleach?

When temp is high, corals expell their zooxathanellae

What is the most effective and fastest way to reduce ocean acidification?

Reduce CO2 emissions from combustion of fossil fuels

How does the amount of CO2 in the atmosphere affect Earth's energy budget?

More heat will be absorbed and trapped in the atmos from CO2

Answers

1
Why is ocean acidification a problem for animals that build their shells out of carbonate?
All of the above
Lower pH lowers the amount of carbonate avaliable for use
When the pH is more acidic it helps the shell harden
Soft bodies of the animal cannot withstand the lower pH
2
Why do continents warm faster than oceans?
Oceans and continents warm at the same rate
Low specific heat so they release energy faster than H2O
Low albedo so they absorb energy more radiant energy
High specific heat so they release energy slower than H2O
3
Which source of ice would increase sea level the LEAST if it were to melt?
The ice on Greenland
Antarctic Ice
Glacial ice
Icebergs
4
How warm does the SST need to get for the corals to experience thermal stress?
1° higher than the max winter temperature for that area
5° warmer than the max summer temperature for <br>that area
1° warmer than the max summer temperature for that area
5° warmer than the max winter temperture for that area
5
Which of the following is the most concentrated source of CO₂ in the atmosphere?
Exhaust from combustion of organic materials
Expelled gas from cellular respiration
The ocean
None of these
6
What is the reason for the seasonal up and down pattern each year. Show on the Keeling Curve.
CO2 in the summer decreases due to photosynthesis
In the summer, melting ice caps release CO2 into the air
Measurements are hard to get in the winter
In the summer the ocean relseases large amounts of CO2
7
For a given atmospheric CO₂ level, why does the pH stay higher when the temp is higher?
pH is not dependent on temperture
Warmer water will absorb less atmospheric CO2
Cooler water will absorb less atmospheric CO2
Once the CO2 is absorbed in warmer water less=carbonic acid
8
Why does high temperature cause corals to bleach?
When temps are high, fish eat more of the coral = bleaching
When temp is high, there is more CO2 that is toxic to corals
When temp is high, corals expell their zooxathanellae
When temp is high, enzymes in coral become denatured = dead
9
What is the most effective and fastest way to reduce ocean acidification?
Eat less shellfish
Make oceans colder by increasing glacial melt
There is no way to reduce ocean acidification
Reduce CO2 emissions from combustion of fossil fuels
10
How does the amount of CO₂ in the atmosphere affect Earth's energy budget?
More heat released back to atmos becuase CO2 is reflective
More heat will be absorbed and trapped in the atmos from CO2
CO2 in the atmosphere does NOT affect Earth's heat budget
Less heat gets to Earth due to the CO2 heavy atmosphere
