The natural greenhouse effect is when greenhouse gases (a) heat our atmosphere.
What impact does the natural greenhouse effect have?
It cools the Earth’s surface
It makes the earth warm enough for life to exist
It increases the amount of oxygen in the atmosphere
It reduces the amount of carbon dioxide in the atmosphere
What is the human-enhanced greenhouse effect?
A natural process that cools the Earth’s atmosphere
The trapping of too much heat in the atmosphere due to increased greenhouse gases
A reduction in greenhouse gases caused by planting more trees
A process that prevents any heat from being trapped in the atmosphere
What is the main cause of the human-enhanced greenhouse effect?
Volcanic eruptions
Increased levels of greenhouse gases due to human activites
Natural fluctuations in the Earth’s orbit
Solar radiation
What does "emissions" mean when we are talking about climate change?
The release of greenhouse gases like CO2 and methane into the atmosphere
The absorption of sunlight by the Earth’s surface
The melting of polar ice caps
The formation of clouds in the atmosphere
What does "emissions per capita" mean?
Total emissions of a country divided by its population
Total emissions of a country multiplied by its population
The emissions produced by one industry in a country
The emissions produced by natural processes only
What is global warming?
A natural cooling of the Earth’s surface
The long-term increase in the Earth’s average temperature due to human activities
A temporary increase in temperature caused by volcanic eruptions
A decrease in the Earth’s temperature due to reduced sunlight
Which three industries emit the most CO₂?
Electricty and Heat Generation
Fashion
Transport
Manufacturing and Construction
Select two reasons that global warming is causing the sea levels to rise.
Increased rainfall in coastal areas
Thermal expansion (热膨胀) of seawater as it warms
Melting of glaciers and ice sheets due to increased temperatures
Reduced ocean temperatures
Select the primary impacts of climate change.
Flooding
Rising Temperatures
Coral bleaching
Extreme Weather
Select the secondary impacts of climate change
Water scarcity
Rising ocean temperatures
Displacement - 流离失所
Coral bleaching
How is climate change affecting the water cycle?
It causes all regions to experience more rainfall
It reduces evaporation globally
It leads to heavier rainfall in some areas and extended droughts in others
It stabilizes rainfall patterns worldwide
What aspects of extreme weather events are changing due to climate change?
Frequency (how often they occur)
Intensity (how strong they are)
Duration (how long they are)
Frequency, Intensity, Duration, and where they occur.
What is coral bleaching?
A process where corals lose their color due to warming ocean temperatures
A natural process where corals grow faster
A result of increased ocean salinity
A process where corals absorb more nutrients
What is causing coral bleaching?
Warmer ocean temperatures and increased acidity
Reduced sunlight reaching the ocean floor
Increased rainfall over coral reefs
Decreased ocean temperatures
How can coral bleaching impact humans?
Loss of income for communities dependent on fishing and tourism
Increased protection against coastal storms due to healthier reefs
Reduced biodiversity (生物多样性), affecting food sources and livelihoods
Improved water quality in coastal areas
