Topic: Climate Change
Grade: 10
Question 1:
Which of the following is a greenhouse gas?
A) Nitrogen
B) Oxygen
C) Carbon Dioxide
D) Argon
Answer: C) Carbon Dioxide
Explanation: Carbon dioxide is a greenhouse gas that contributes to the greenhouse effect, which leads to global warming. It is released into the atmosphere through activities such as burning fossil fuels and deforestation. An example of the impact of carbon dioxide emissions is the melting of polar ice caps, which results in rising sea levels and threatens coastal communities. Another example is the increased frequency and intensity of heatwaves and extreme weather events.
Question 2:
What is the main cause of climate change?
A) Natural factors
B) Human activities
C) Solar radiation
D) Volcanic eruptions
Answer: B) Human activities
Explanation: Human activities, such as the burning of fossil fuels, deforestation, and industrial processes, are the main contributors to climate change. These activities release greenhouse gases into the atmosphere, which trap heat and lead to an increase in global temperatures. For example, the burning of coal for electricity generation releases carbon dioxide, a greenhouse gas, into the atmosphere. Another example is deforestation, which reduces the Earth\’s capacity to absorb carbon dioxide through photosynthesis.
Question 3:
Which of the following is an effect of climate change?
A) Decreased biodiversity
B) Increased food production
C) Reduced energy consumption
D) Improved air quality
Answer: A) Decreased biodiversity
Explanation: Climate change has a negative impact on biodiversity as it disrupts ecosystems and affects the distribution and behavior of species. For example, rising temperatures can lead to coral bleaching, resulting in the loss of coral reefs and the marine species that rely on them. Another example is the loss of habitat for polar bears due to the melting of Arctic sea ice, which threatens their survival.
Question 4:
What is the significance of the Paris Agreement?
A) It aims to limit global temperature rise to well below 2 degrees Celsius.
B) It promotes the use of fossil fuels.
C) It encourages deforestation.
D) It allows countries to increase their greenhouse gas emissions without consequences.
Answer: A) It aims to limit global temperature rise to well below 2 degrees Celsius.
Explanation: The Paris Agreement is a global effort to combat climate change by limiting global temperature rise to well below 2 degrees Celsius above pre-industrial levels. It aims to strengthen the global response to climate change and enhance the ability of countries to adapt to its impacts. The agreement sets out a framework for countries to regularly review and report on their progress in reducing greenhouse gas emissions. An example of the significance of the Paris Agreement is the commitment of countries to transition to renewable energy sources, such as solar and wind power, to reduce carbon emissions.
Question 5:
What is the role of the Intergovernmental Panel on Climate Change (IPCC)?
A) To promote climate change denial
B) To conduct scientific research on climate change
C) To develop policies to address climate change
D) To advocate for the use of fossil fuels
Answer: B) To conduct scientific research on climate change
Explanation: The Intergovernmental Panel on Climate Change (IPCC) is a scientific body that assesses the scientific, technical, and socioeconomic information relevant to understanding climate change. Its role is to provide policymakers with objective and comprehensive assessments of the current state of knowledge on climate change and its potential impacts. The IPCC does not promote climate change denial or advocate for the use of fossil fuels. An example of the IPCC\’s work is its assessment reports, which synthesize the latest scientific research on climate change and inform global climate policy discussions.
