What does it mean for an energy source to be renewable?
It can be replaced naturally in a short period of time.
What does nonrenewable mean?
It cannot be replaced in a short period of time once used.
What gas traps heat in the atmosphere?
Greenhouse gases (like CO₂, methane).
What is happening to global average temperatures?

Name one example of a renewable energy source that uses moving air.
Wind energy
Name two examples of nonrenewable resources.
Oil and natural gas (or coal, nuclear).
What human activity is the largest source of greenhouse gas emissions?
Burning fossil fuels
How does melting ice affect sea levels?
It causes sea levels to rise.
Which renewable source uses sunlight to generate electricity?
Solar energy
What fossil fuel is formed from ancient plant material?
Coal
How does deforestation contribute to climate change?
Trees absorb CO₂, so cutting them down increases CO₂ levels.
Name one effect of climate change on weather patterns.
More intense storms, droughts, floods, or heat waves.
What type of renewable energy comes from heat inside the Earth?
Geothermal energy.
Why are fossil fuels bad for the environment?
They release carbon dioxide and other greenhouse gases when burned.
What is the greenhouse effect?
The process where gases in Earth’s atmosphere trap heat from the Sun.
Name one action people can take to reduce carbon emissions.
Drive less, use renewable energy, plant trees, or save electricity.
Why are renewable energies considered more sustainable for the future?
They don’t run out and produce little or no greenhouse gases.
This resource comes from uranium atoms fusing together or a fission reaction and separating
Nuclear
Name two greenhouse gases other than CO₂.
Methane, Nitrous oxide, sulphur dioxide, F gases, water vapor
What is carbon footprint?
The total amount of greenhouse gases a person or activity produces.
