The greenhouse effect Flashcards
What is the greenhouse effect?
The greenhouse effect is the process by which certain gases in Earth’s atmosphere trap heat, keeping the planet warm.
Name one major greenhouse gas.
Carbon dioxide (CO2)
True or False: The greenhouse effect is entirely harmful to the environment.
False
What human activities contribute to increased greenhouse gas emissions?
Burning fossil fuels, deforestation, and industrial processes.
Fill in the blank: The main source of carbon dioxide emissions is ______.
burning fossil fuels
What role do plants play in the greenhouse effect?
Plants absorb carbon dioxide during photosynthesis, helping to reduce greenhouse gas levels.
Multiple choice: Which gas is considered the most potent greenhouse gas per molecule?
Methane (CH4)
What is the impact of increased greenhouse gases on global temperatures?
Increased greenhouse gases lead to higher global temperatures, causing climate change.
True or False: The greenhouse effect helps maintain temperatures necessary for life on Earth.
True
What is the difference between natural and anthropogenic greenhouse gases?
Natural greenhouse gases come from natural processes, while anthropogenic greenhouse gases are produced by human activities.
Fill in the blank: The greenhouse effect is essential for maintaining Earth’s ______.
temperature
What is global warming?
Global warming refers to the long-term increase in Earth’s average surface temperature due to human activities and greenhouse gas emissions.
How do aerosols affect the greenhouse effect?
Aerosols can cool the atmosphere by reflecting sunlight away from the Earth.
Multiple choice: Which of the following is NOT a greenhouse gas?
Oxygen (O2)
What is the main consequence of climate change related to the greenhouse effect?
Rising sea levels due to melting ice caps and glaciers.
True or False: The greenhouse effect only occurs during the day.
False
What is the Kyoto Protocol?
An international agreement aimed at reducing greenhouse gas emissions.
Fill in the blank: ______ is a consequence of increased greenhouse gases leading to extreme weather events.
Climate change
How does the greenhouse effect relate to the carbon cycle?
The carbon cycle regulates the levels of carbon dioxide in the atmosphere, which impacts the greenhouse effect.
What is the role of the ozone layer in relation to the greenhouse effect?
The ozone layer protects the Earth from harmful ultraviolet (UV) radiation but is not a greenhouse gas.
Multiple choice: Which of the following contributes to the greenhouse effect?
Deforestation
What is one method to reduce greenhouse gas emissions?
Increasing energy efficiency.
True or False: Water vapor is the most abundant greenhouse gas in the atmosphere.
True
What are carbon sinks?
Natural systems that absorb more carbon than they release, such as forests and oceans.
