Burning fossil fuels
What happens to sea levels as global temperatures rise?
They rise due to melting ice and thermal expansion
What type of energy reduces emissions by replacing fossil fuels?
Renewable energy
What is the process that traps heat in Earth’s atmosphere?
The greenhouse effect
True or False: Climate change affects every continent.
True
What gas is most responsible for human‑caused global warming?

What type of weather event becomes more frequent with warming?
Heatwaves
Planting trees helps fight climate change by absorbing what gas?
CO₂
What layer of the atmosphere contains most greenhouse gases?
The troposphere
What country currently emits the most CO₂ per year?
China
Which sector produces the most greenhouse gas emissions globally?

Adaptation
What do scientists use to study past climates?
Ice cores
What natural disaster can be worsened by rising sea levels?
