Greenhouse Gases
This gas is released by livestock and has a warming potential roughly 28 times higher than CO₂
What is methane?
Albedo is a measure of surface reflectivity. It is scaled from 0 to this number
What is 1?
Melting of this specific type of ice directly contributes to global sea-level rise
What is land-based ice?
What are glaciers?
A sudden severe thunderstorm in Melbourne is an example of this atmospheric state
What is weather?
This category of personal footprint measures the total greenhouse gas emissions generated by your lifestyle
What is a carbon footprint?
This is the primarily naturally occurring greenhouse gas that traps the most heat in the atmosphere
What is water vapour?
This colour surface has the highest albedo rating, reflecting the majority of incoming sunlight
What is white?
The ice caps are part of one of the four Earth's spheres
What is the hydrosphere?
This concept describes the long-term, 30-year average of regional atmospheric patterns
What is climate?
This weak acid is formed when atmospheric carbon dioxide dissolves in seawater
What is carbonic acid?
One of the following is not a greenhouse gas.
-CO₂
-CH₄
-H₂O
-N₂
What is N₂?
What is nitrogen gas?
The more ice melts, the more the dark water underneath absorbs heat, meaning more ice melts, and so on...
This is a kind of feedback loop.
What is a positive feedback loop?
Melting ice alters the salinity of the ocean.
This change (increases/decreases) the salt content.
What is a decrease?
An increase in the frequency and severity of extreme bushfires over decades indicates a shift in this
What is climate?
As of 2015, this country has the highest carbon emissions per head
What is USA?
These synthetic, industrial chemical compounds destroy ozone and have the longest atmospheric lifespan
What are fluorinated gases?
What are CFCs?
This is the average planetary albedo
What is 30%?
When this type of ice melts, it does not contribute to rising global sea levels
What is sea ice?
The El Niño system is an example of this phenomenon
What is a climate phenomenon?
Ocean acidification directly threatens marine life by breaking down this structural compound
What is calcium carbonate?
