Terms in this Study Set(24)
Greenhouse Gas Identification(12)
CO2 sources?
Burning fossil fuels, deforestation, industrial processes.
True or False: Methane has a higher GWP than CO2.
True. Methane has a GWP of 25 over 100 years.
Name a gas with a GWP over 1000.
Sulfur hexafluoride (SF6) - GWP: 22,800.
Water vapor impact?
Most abundant greenhouse gas, amplifies warming effect.
Key source of nitrous oxide?
Agricultural activities, especially fertilizer use.
Fill in the blank: _____ is released during anaerobic decomposition.
Methane (CH4).
Which gas is a product of fossil fuel combustion?
Carbon dioxide (CO2).
Global warming potential of CO2?
Reference gas; GWP = 1.
How does deforestation affect atmospheric CO2?
Reduces carbon sinks, increasing CO2 levels.
Comparison: CO2 vs. CH4.
CO2: long-term presence; CH4: short-term potency.
What is the main source of fluorinated gases?
Industrial applications, refrigeration, and air conditioning.
Effects of increased greenhouse gases?
- Higher global temperatures - Increased weather extremes - Sea level rise
Global Warming Potential (GWP)(12)
What is Global Warming Potential (GWP)?
GWP is a measure of how much a given mass of greenhouse gas contributes to global warming compared to carbon dioxide over a specified time, typically 100 years.
Which gas has the highest GWP?
Sulfur hexafluoride (SF6) with a GWP of 23,500.
True or False: Methane has a higher GWP than carbon dioxide.
True. Methane has a GWP of 28-36 times that of CO2 over 100 years.
Fill in the blank: The GWP of nitrous oxide is ___ over 100 years.
298.
Compare the GWP of CO2 and CH4.
CO2: GWP = 1, CH4: GWP = 28-36. CH4 is significantly more effective at trapping heat.
What is the GWP of HFC-134a?
HFC-134a has a GWP of 1,430, making it much more potent than CO2.
Cause → Effect: Increased levels of CO2 lead to ___ in temperature.
Increased global temperatures due to enhanced greenhouse effect.
How long does methane stay in the atmosphere?
Methane persists in the atmosphere for about 12 years before it is broken down.
What is the significance of a gas's GWP?
It helps prioritize efforts to reduce emissions of the most impactful greenhouse gases.
True or False: All greenhouse gases have the same GWP.
False. Each gas has a different GWP based on its heat-trapping abilities.
Fill in the blank: The GWP of perfluorocarbons (PFCs) can exceed ___ over 100 years.
9,000.
Question: Which has a higher GWP: N2O or CH4?
N2O (298) has a higher GWP than CH4 (28-36).
