Environmental Impact and Land Use Quiz

Carbon dioxide is the primary greenhouse gas responsible for trapping heat in the atmosphere, leading to global warming.

Eutrophication leads to excessive growth of algae in water bodies due to high nutrient levels, resulting in oxygen depletion and harm to aquatic ecosystems.

Industrial discharges, particularly from coal-fired power plants and certain industrial processes, are a significant source of mercury pollution in aquatic ecosystems.

Chlorofluorocarbons (CFCs) released from human activities, such as refrigerants and aerosols, are the primary cause of ozone layer depletion, leading to the formation of the ozone hole.

Habitat destruction, including deforestation, urbanization, and land conversion for agriculture, is a major factor contributing to the loss of biodiversity by reducing available habitats for various species.

Deforestation is mainly carried out to obtain timber and create space for agricultural activities, leading to habitat loss and environmental degradation.

Natural gas is a non-renewable energy source formed from fossilized organic materials, which cannot be replenished on a human timescale.

Chlorofluorocarbons (CFCs) released from human activities are the primary cause of ozone layer depletion, leading to increased ultraviolet radiation reaching the Earth's surface.

The Paris Agreement is a global accord aiming to limit global warming well below 2 degrees Celsius above pre-industrial levels and pursuing efforts to limit it to 1.5 degrees Celsius.

Hazardous waste, due to its toxicity and potential harm to human health and the environment, presents significant challenges in its management and disposal.

Coral bleaching is primarily caused by environmental stressors, particularly elevated sea temperatures due to global warming, leading to the expulsion of symbiotic algae from coral tissues.

Biomass is a renewable energy source derived from organic materials such as wood, crop residues, and organic waste, which can be converted into energy through various processes like combustion and anaerobic digestion.

Heavy rainfall can cause soil erosion by washing away the topsoil, leading to land degradation and loss of fertility.

A carbon footprint represents the total amount of greenhouse gases emitted directly or indirectly by human activities, indicating their impact on climate change.

Global warming refers to the long-term increase in the Earth's average surface temperature, primarily due to human activities such as burning fossil fuels and deforestation.

Agroforestry involves integrating trees and shrubs into agricultural landscapes, promoting biodiversity, soil health, and sustainable land use.

Carbon monoxide, produced by incomplete combustion of fossil fuels, is a major contributor to indoor air pollution, posing serious health risks.

Biodiversity hotspots are regions with exceptionally high levels of species richness and a significant threat of habitat loss, often harboring many critically endangered species.

Sulfur dioxide, primarily emitted from burning fossil fuels containing sulfur, reacts with water vapor in the atmosphere to form sulfuric acid, a major component of acid rain.
