Climate Change Challenge

What is the main cause of global warming?

• Volcanic eruptions

• Solar flares

• Increase in greenhouse gases

• Deforestation

How does deforestation contribute to global warming?

• Deforestation reduces the number of trees that can absorb carbon dioxide, releasing stored carbon back into the atmosphere as CO2.

• Deforestation leads to the growth of new forests that offset the carbon emissions.

• Deforestation increases the number of trees that absorb carbon dioxide, reducing CO2 levels in the atmosphere.

• Deforestation has no impact on global warming as it is a natural process.

Name one effect of global warming on the environment.

• Decreased rainfall

• Rising sea levels

• Expansion of polar ice caps

• Increased biodiversity

How can renewable energy sources help reduce global warming?

• Renewable energy sources have no impact on global warming.

• Renewable energy sources reduce global warming by producing electricity without emitting greenhouse gases.

• Renewable energy sources increase global warming by releasing more greenhouse gases.

• Renewable energy sources contribute to global warming by depleting natural resources.

What is a carbon footprint?

• The distance between carbon atoms in a molecule

• The amount of oxygen consumed by plants

• The total amount of greenhouse gases emitted by human activities.

• The number of trees in a forest

Explain how individuals can reduce their carbon footprint.

• By supporting fossil fuel industries

• By using public transportation, carpooling, biking or walking instead of driving, reducing energy consumption at home, eating a plant-based diet, and supporting renewable energy sources.

• By driving alone in a car everywhere

• By increasing energy consumption at home

What are some examples of renewable energy sources?

• Solar energy, wind energy, hydroelectric power, geothermal energy, biomass

• Coal energy

• Nuclear energy

• Oil energy

How does the burning of fossil fuels impact global warming?

• Burning fossil fuels reduces global warming

• Burning fossil fuels helps to cool the planet

• Burning fossil fuels has no impact on global warming

• Burning fossil fuels releases greenhouse gases that trap heat in the atmosphere, contributing to global warming.

What role does methane play in global warming?

• Methane reduces the greenhouse effect

• Methane has no impact on global warming

• Methane absorbs UV radiation and cools the atmosphere

• Methane contributes to global warming by trapping heat in the atmosphere.

Why is it important to reduce greenhouse gas emissions?

• To accelerate the depletion of the ozone layer

• To mitigate climate change and its adverse effects.

• To increase global warming

• To promote environmental conservation
