Human Impact On The Earths Atmosphere Flashcards
(26 cards)
What are the primary greenhouse gases emitted by human activities?
Carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).
True or False: The burning of fossil fuels contributes to the increase of greenhouse gases in the atmosphere.
True.
Fill in the blank: Deforestation leads to increased levels of ______ in the atmosphere.
carbon dioxide.
What is the main source of methane emissions?
Agriculture, particularly from livestock digestion and manure management.
Multiple choice: Which of the following is NOT a consequence of increased greenhouse gases?
Decreased global temperatures.
What is the role of carbon sinks in relation to atmospheric CO2?
They absorb CO2 from the atmosphere, helping to mitigate climate change.
True or False: Urbanization has no impact on local weather patterns.
False.
What is acid rain and how is it formed?
Acid rain is precipitation that contains harmful levels of sulfuric and nitric acids, formed by the reaction of sulfur dioxide and nitrogen oxides with water vapor in the atmosphere.
Fill in the blank: The greenhouse effect is essential for maintaining ______ on Earth.
life.
What human activity is the largest contributor to global warming?
Burning fossil fuels for energy and transportation.
Multiple choice: Which gas is primarily responsible for the depletion of the ozone layer?
Chlorofluorocarbons (CFCs).
What is the significance of the ozone layer?
It protects living organisms from harmful ultraviolet (UV) radiation from the sun.
True or False: Increased levels of CO2 can lead to ocean acidification.
True.
What impact does transportation have on air quality?
Transportation contributes to air pollution through the emission of nitrogen oxides, particulates, and volatile organic compounds.
Fill in the blank: The Kyoto Protocol aimed to reduce ______ emissions globally.
greenhouse gas.
What are aerosols and how do they affect the atmosphere?
Aerosols are tiny particles suspended in the atmosphere that can affect climate by scattering and absorbing sunlight.
Multiple choice: Which of the following is a renewable energy source that can reduce human impact on the atmosphere?
Solar energy.
What is the effect of increased carbon dioxide on global temperatures?
It leads to an increase in global temperatures, contributing to climate change.
True or False: Industrial processes have no effect on the atmosphere.
False.
What are the potential health impacts of air pollution?
Respiratory diseases, cardiovascular diseases, and premature death.
Fill in the blank: The term ‘carbon footprint’ refers to the total amount of ______ emitted by an individual or organization.
carbon dioxide.
What is the purpose of carbon trading?
To limit greenhouse gas emissions by allowing companies to buy and sell emissions allowances.
What role do trees play in combating climate change?
They absorb CO2 from the atmosphere during photosynthesis.
Multiple choice: Which of the following activities can help reduce greenhouse gas emissions?
Using public transportation instead of driving.
