2.2 Test Review

Front

What are renewable sources of energy?

Back

Renewable sources of energy are energy sources that are replenished naturally and can be used repeatedly. Examples include wind energy and solar energy.

Front

What is the environmental impact of fossil fuels?

Back

Fossil fuels, such as coal, oil, and natural gas, produce carbon dioxide when burned, contributing to air pollution and climate change.

Front

What is the primary greenhouse gas emitted by burning fossil fuels?

Back

Carbon dioxide (CO2) is the primary greenhouse gas emitted from burning fossil fuels.

Front

What is the difference between renewable and non-renewable energy sources?

Back

Renewable energy sources can be replenished naturally (e.g., solar, wind), while non-renewable sources (e.g., fossil fuels) are finite and can deplete.

Front

What is a fossil fuel?

Back

Fossil fuels are natural substances formed from the remains of ancient plants and animals, primarily consisting of hydrocarbons. Examples include coal, oil, and natural gas.

Front

What is the impact of increased coal consumption on greenhouse gas emissions?

Back

Increased coal consumption leads to higher greenhouse gas emissions, particularly carbon dioxide, contributing to global warming.

Front

Which energy source is considered the most damaging to the environment?

Back

Fossil fuels are considered the most damaging to the environment due to their emissions and extraction processes.

Front

What are some examples of renewable energy sources?

Back

Examples of renewable energy sources include solar energy, wind energy, hydroelectric power, and geothermal energy.

Front

What is the role of solar energy in reducing carbon emissions?

Back

Solar energy generates electricity without emitting carbon dioxide, helping to reduce overall carbon emissions.

Front

What are the environmental benefits of using wind energy?

Back

Wind energy produces no air pollutants or greenhouse gases during operation, making it a clean and sustainable energy source.
