Q: What is climate change?
A: Long-term changes in Earth’s average weather, like temperature and rainfall.
Q: What is the greenhouse effect?
A: Heat is getting trapped near Earth by greenhouse gases.
Q: Name 3 greenhouse gases.
A: Carbon dioxide, methane, water vapour.
Q: Why are greenhouse gases important?
A: They keep Earth warm enough for life.
Q: What happens if there are too many greenhouse gases?
A: Global warming and climate change.
Q: What causes climate change?
A: Natural events and human activities.
what is human activity? Give two scientific reasons for your answer. Why is it important to climate change? How does it help climate change?
• Human activities, such as burning coal, oil, and gas, are the primary cause of climate change. • These actions lead to a warmer planet, causing problems like melting glaciers and rising sea levels. • They release greenhouse gases, such as carbon dioxide (CO2) and methane, which trap heat in the atmosphere. • Scientists have found that today’s CO2 levels are the highest they’ve been in 800,000 years, largely due to burning fossil fuels since the Industrial Revolution.
Q: What’s the difference between natural and enhanced greenhouse gases?
A: Natural greenhouse gases occur naturally and maintain earth’s habitable temperature, while anthropogenic (human-caused) greenhouse gases, produced by fossil fuels and land use, increase atmospheric concentrations, driving global warming.
Q: What is short-term climate change?
A: Temporary weather changes lasting days to years.
Q: Give one example of short-term climate change.
A: A heat wave or heavy snowfall.
Q: What is long-term climate change?
A: Permanent climate shifts over decades or longer.
Q: Give one example of long-term climate change.
A: Global warming.
Q: How does climate change affect agriculture?
A: Lower crop production and water shortages.
Q: How does climate change affect human health?
A: More diseases and respiratory problems.
