C1 Advanced Speaking Climate and Environment Vocabulary Quiz

Carbon sequestration refers to the method of capturing carbon dioxide emissions from sources like power plants and storing it underground or in various natural reservoirs. This process helps mitigate climate change by reducing the amount of CO2 in the atmosphere, thereby lowering greenhouse gas concentrations and their harmful effects on global warming.

Resilience refers to an ecosystem's capacity to absorb disturbances and still maintain its essential functions and structure. It highlights the system's ability to recover from disruptions, such as natural disasters or human impacts, ensuring the continuity of ecological processes and biodiversity. A resilient ecosystem can bounce back and adapt to changing conditions.

Biodiversity refers to the variety of life forms within a given ecosystem, encompassing the different species and their genetic variations. It is essential for ecosystem resilience, productivity, and overall health, as diverse biological communities can better withstand environmental changes and provide vital ecosystem services.

Sustainable development in environmental contexts emphasizes balancing economic growth with ecological preservation. It aims to fulfill current needs while ensuring that future generations can also meet their needs. This approach advocates for responsible resource use and environmental stewardship, avoiding practices that deplete natural resources or cause long-term harm to the planet.

Climate mitigation focuses on strategies and actions aimed at decreasing the sources or enhancing the sinks of greenhouse gases. This includes initiatives such as transitioning to renewable energy, improving energy efficiency, and promoting sustainable practices to limit the impact of climate change and reduce global warming.

Global warming refers to the long-term increase in Earth's average surface temperature due to human activities, primarily the emission of greenhouse gases. This phenomenon leads to climate change, impacting weather patterns, sea levels, and ecosystems globally. It is distinct from other environmental issues like ozone depletion or acid rain.

Renewable energy refers to energy derived from sources that are naturally replenished over time, such as sunlight, wind, rain, and geothermal heat. Unlike fossil fuels, which are finite and deplete over time, renewable energy sources are sustainable and can be harnessed continuously without the risk of exhaustion.

The ecological footprint quantifies the environmental impact of human activities by measuring the amount of natural resources consumed and waste produced. It reflects how much land and water area is required to sustain a person's lifestyle, highlighting the balance between human demands and the planet's capacity to regenerate resources.

Deforestation leads to the removal of trees, which disrupts forest ecosystems and their biodiversity. Additionally, it contributes to increased carbon emissions as trees that absorb carbon dioxide are cut down, exacerbating climate change. This loss of forest cover has significant environmental impacts, including habitat destruction and reduced air quality.

Climate adaptation refers to the process of adjusting strategies, policies, and practices to minimize the negative effects of climate change. It involves making necessary changes to infrastructure, ecosystems, and communities to cope with the impacts of changing weather patterns, rather than attempting to prevent all climate-related disasters or reverse existing trends.

Eutrophication occurs when water bodies receive an excess of nutrients, primarily nitrogen and phosphorus, often from agricultural runoff or wastewater. This nutrient overload stimulates rapid algal growth, known as algal blooms, which can deplete oxygen levels and harm aquatic life, disrupting the ecosystem balance.

The greenhouse effect occurs when certain gases in the Earth's atmosphere trap heat from the sun, preventing it from escaping back into space. This process warms the planet, enabling a stable climate and supporting life. Other options do not accurately represent the primary function of the greenhouse effect.
