Analysis of Environmental Issues and Solutions Quiz

Carbon dioxide is a well-known greenhouse gas that contributes to global warming.

Natural gas, while cleaner than many fossil fuels, is not considered renewable as it is a finite resource formed from ancient organic matter.

Catalytic converters help reduce harmful emissions by converting pollutants in the exhaust gases into less harmful substances.

Anaerobic digestion is the breakdown of organic matter by microorganisms in the absence of oxygen, producing biogas and nutrient-rich digestate.

Coal is a fossil fuel formed from decayed plant material over millions of years and is not renewable on human timescales.

CFCs are synthetic compounds used in refrigeration and aerosols, which break down ozone molecules in the atmosphere.

Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released into the atmosphere.

Eutrophication is the excessive enrichment of a body of water with nutrients, often due to runoff from the land, leading to increased plant growth and depletion of oxygen.

Agriculture, particularly commercial farming and livestock grazing, is the leading cause of deforestation worldwide.

Coral reef bleaching occurs when corals expel the algae living in their tissues, often due to stress from increased sea temperatures.

Urbanization involves the conversion of natural habitats into urban areas for human settlement and infrastructure development.

In a sustainable ecosystem, nutrients are recycled through various processes, ensuring a balance in the ecosystem's functions.

The greenhouse effect refers to the process whereby heat is trapped in the Earth's atmosphere by greenhouse gases, leading to a rise in global temperatures.

Coal-fired power plants release significant amounts of mercury into the atmosphere, which eventually settles into oceans through deposition.

Ocean acidification inhibits the ability of marine organisms like corals, shellfish, and plankton to form calcium carbonate, essential for their shells and skeletons.

The Paris Agreement is an international treaty signed by almost all countries, aiming to limit global warming by reducing greenhouse gas emissions and adapting to climate change impacts.

Sulfur dioxide and nitrogen oxides, primarily emitted from burning fossil fuels, react with water vapor in the atmosphere to form sulfuric acid and nitric acid, causing acid rain.
