AS Geography: Climate Change

What are the main greenhouse gases responsible for climate change?

• Oxygen (O2), helium (He), and argon (Ar)

• Carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O)

Explain the difference between weather and climate.

• Climate only refers to temperature

• Weather and climate both describe short-term conditions

• The main difference between weather and climate is the timescale and the scope of the conditions they describe.

• Weather is the same as climate

How does deforestation contribute to climate change?

• Deforestation increases the number of trees available to absorb carbon dioxide, leading to a decrease in greenhouse gases and reducing climate change.

• Deforestation has no impact on climate change as it only affects the local environment.

• Deforestation reduces the number of trees available to absorb carbon dioxide, leading to an increase in greenhouse gases and contributing to climate change.

• Deforestation leads to an increase in oxygen production, which has no effect on climate change.

Discuss the impact of climate change on sea levels and coastal areas.

• Climate change has no impact on sea levels and coastal areas.

• Climate change only affects sea levels, not coastal areas.

• Climate change causes sea levels to decrease, leading to more land in coastal areas.

• Climate change causes sea levels to rise, leading to increased flooding, erosion, and loss of coastal habitats.

What are some of the potential solutions to mitigate climate change?

• Promoting unsustainable agriculture practices

• Increasing fossil fuel consumption

• Transitioning to renewable energy sources, improving energy efficiency, reducing deforestation, promoting sustainable agriculture, and implementing policies to reduce greenhouse gas emissions.

• Encouraging deforestation

Explain the concept of the greenhouse effect and its role in climate change.

• The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without its atmosphere. It plays a significant role in climate change by contributing to the rise in global temperatures and the associated impacts on weather patterns, sea levels, and ecosystems.

• The greenhouse effect has no role in climate change and is not responsible for the rise in global temperatures.

• The greenhouse effect is the process by which radiation from a planet's atmosphere cools the planet's surface to a temperature below what it would be without its atmosphere.

• The greenhouse effect only affects local weather patterns and has no impact on global climate change.

Discuss the impact of climate change on agriculture and food security.

• Climate change has no impact on agriculture and food security.

• Climate change can have a significant negative impact on agriculture by reducing crop yields and increasing the risk of food insecurity.

• Climate change only affects food security but not agriculture.

• Climate change leads to increased crop yields and improved food security.

What are the consequences of melting ice caps and glaciers due to climate change?

• Expansion of polar bear habitats

• Consequences of melting ice caps and glaciers due to climate change include rising sea levels, loss of habitat for polar animals, changes in ocean currents, and increased risk of natural disasters such as flooding and landslides.

• Decrease in global temperatures

• Reduction in greenhouse gas emissions

Explain the concept of carbon footprint and its significance in addressing climate change.

• Carbon footprint is the total amount of plastic waste emitted by human activities and it is significant in addressing climate change as it helps in ignoring the sources of emissions.

• Carbon footprint is the total amount of greenhouse gases emitted by human activities and it is significant in addressing climate change as it helps in identifying and reducing the sources of emissions.

• Carbon footprint is the amount of oxygen emitted by human activities and it is significant in addressing climate change as it helps in increasing the sources of emissions.

• Carbon footprint is the total amount of water vapor emitted by human activities and it is significant in addressing climate change as it helps in reducing the sources of emissions.

Discuss the role of international agreements and policies in addressing climate change.

• International agreements and policies are too costly and ineffective in addressing climate change.

• International agreements and policies have no impact on addressing climate change.

• International agreements and policies only benefit developed countries, leaving developing countries to deal with climate change on their own.

• International agreements and policies play a crucial role in addressing climate change by setting targets for reducing greenhouse gas emissions, promoting renewable energy, and encouraging sustainable practices.
