Climate Change

Front

Increasing quantities of CO₂ (Carbon Dioxide) in the atmosphere will cause air temperatures to be _____.

Back

warmer

Answer explanation

Increasing CO2 levels trap heat in the atmosphere, leading to a greenhouse effect. This results in higher air temperatures, making the correct answer 'warmer'.

Front

Which of the following is NOT evidence of global warming? Sea level rising, Loss of Arctic Sea Ice, Less Water Vapor in the Air, More extreme weather events

Back

Less Water Vapor in the Air

Answer explanation

Less Water Vapor in the Air is NOT evidence of global warming, as increased temperatures typically lead to more water vapor. In contrast, rising sea levels, loss of Arctic sea ice, and more extreme weather events are clear indicators of global warming.

Front

Climate change causes extreme weather conditions such as: Flooding, Heat Waves, Hurricanes, All of the above

Back

All of the above

Answer explanation

Climate change leads to various extreme weather events, including flooding, heat waves, and hurricanes. Therefore, the correct answer is 'All of the above' as all these conditions are influenced by climate change.

Front

The amount of carbon dioxide CO₂ in the atmosphere is decreasing.

Back

False

Answer explanation

The statement is false because the amount of carbon dioxide CO2 in the atmosphere is actually increasing due to human activities, such as burning fossil fuels and deforestation.

Front

Which human activity contributes the MOST carbon dioxide to the atmosphere? Options: Fishing, Breathing, Burning Fossil Fuels, Farming

Back

Burning Fossil Fuels

Answer explanation

Burning fossil fuels, such as coal, oil, and natural gas, releases the most carbon dioxide into the atmosphere compared to other activities. This process significantly contributes to global warming and climate change.

Front

Possible human solutions for limiting global warming and climate change are...

Back

being more energy-efficient, using renewable sources of energy, removing carbon from fossil fuel emissions.

Answer explanation

All the options listed are effective human solutions for limiting global warming. Being more energy-efficient reduces consumption, using renewable energy sources decreases reliance on fossil fuels, and removing carbon emissions directly mitigates climate change.

Front

Melting land ice...

Back

causes sea levels to rise because it adds water to the ocean.

Answer explanation

Melting land ice contributes additional water to the ocean, leading to a rise in sea levels. In contrast, melting sea ice does not raise sea levels as it is already floating and displaces its own weight in water.

Front

Which is a natural source of greenhouse gases? Options: aerosols, deforestation, volcanic eruptions, burning fossil fuels

Back

volcanic eruptions

Answer explanation

Volcanic eruptions are a natural source of greenhouse gases, releasing carbon dioxide and other gases into the atmosphere. In contrast, aerosols, deforestation, and burning fossil fuels are primarily human-induced sources.

Front

Everyone has a carbon footprint.

Back

true

Answer explanation

True. A carbon footprint measures the total greenhouse gas emissions caused directly and indirectly by an individual, organization, or product. Therefore, everyone contributes to a carbon footprint.

Front

Which is not going to help reduce our carbon footprint? Options: eating local food, recycling, driving to school, planting trees

Back

driving to school

Answer explanation

Driving to school increases carbon emissions due to fuel consumption, while eating local food, recycling, and planting trees help reduce our carbon footprint by minimizing transportation emissions and enhancing carbon absorption.
