SA2 Flashcards
What are greenhouse gases?
Greenhouse gases are gases that trap heat in the Earth’s atmosphere, contributing to the greenhouse effect.
What is the greenhouse effect?
The greenhouse effect is the warming of the Earth’s surface due to the trapping of heat by greenhouse gases.
Which gas is the most abundant greenhouse gas in the Earth’s atmosphere?
Water vapor is the most abundant greenhouse gas.
True or False: Carbon dioxide is a greenhouse gas.
True
Fill in the blank: The main human activity contributing to increased levels of carbon dioxide is _______.
burning fossil fuels
What are the primary sources of methane emissions?
Primary sources of methane emissions include agriculture, landfills, and natural gas production.
Which greenhouse gas has a higher global warming potential than carbon dioxide?
Methane has a higher global warming potential than carbon dioxide.
What role do forests play in the carbon cycle?
Forests act as carbon sinks, absorbing carbon dioxide from the atmosphere.
What is the impact of deforestation on greenhouse gas levels?
Deforestation increases greenhouse gas levels by releasing stored carbon dioxide.
True or False: Nitrous oxide is a greenhouse gas.
True
What is the major anthropogenic source of nitrous oxide?
The major anthropogenic source of nitrous oxide is agricultural activities, particularly the use of synthetic fertilizers.
Multiple Choice: Which of the following is a greenhouse gas? A) Oxygen B) Argon C) Carbon dioxide D) Nitrogen
C) Carbon dioxide
Fill in the blank: The process of capturing and storing carbon dioxide is known as _______.
carbon capture and storage
What is the main consequence of increased greenhouse gas concentrations?
The main consequence is global warming and climate change.
True or False: Ozone is a greenhouse gas.
True
How does the increase of greenhouse gases affect weather patterns?
It leads to more extreme weather patterns, including more intense storms and prolonged droughts.
What percentage of global greenhouse gas emissions is attributed to the energy sector?
Approximately 73% of global greenhouse gas emissions are attributed to the energy sector.
Multiple Choice: What is a natural source of greenhouse gases? A) Volcanoes B) Cars C) Factories D) Landfills
A) Volcanoes
What is the role of the Intergovernmental Panel on Climate Change (IPCC)?
The IPCC assesses scientific information related to climate change and provides guidance for policymakers.
Fill in the blank: The phenomenon where the Earth’s average temperature rises due to greenhouse gases is called _______.
global warming
What is the relationship between greenhouse gas emissions and climate policy?
Climate policy aims to reduce greenhouse gas emissions to mitigate climate change.
True or False: Reducing greenhouse gas emissions can lead to improved public health.
True
What is carbon footprint?
A carbon footprint is the total amount of greenhouse gases emitted directly and indirectly by an individual, organization, or product.
What are some strategies to reduce greenhouse gas emissions?
Strategies include increasing energy efficiency, transitioning to renewable energy sources, and enhancing carbon sinks.
