• Phenomenon where the Earth's atmospheric temperature is increasing causing widespread environmental changes:

  • Greenhouse Effect
• Substance that pollutes the air, water, or ground, harming living organisms:

  • Pollutant
• Major pollutant from automobile exhaust:

  • CO (Carbon Monoxide)
• Habitat is a particular area inhabited by plants and animals
• Deals with specific resources for humans to use rather than the management of the ecosystem itself:

  • Natural Resources Management
• Halogen-containing gases that convert into more reactive gases when exposed to UV radiation, except:

  • Iodine
• Situation where two or more countries impose negative externality of pollution and suffer from it:

  • Regional Reciprocal Pollution
• Mercury is hazardous to human health because it bio-accumulates high up in the food chain
• Minerals found in run-off from agricultural land and sewage effluents responsible for eutrophication of water bodies:

  • Phosphorus and Carbon
• Free-living amoeba commonly found in water and soil causing a disease known as Primary Amoebic Meningoencephalitis:

  • Naegleria Fowleri
• Nitrous Oxide
• Chlorofluorocarbon
• Carbon Monoxide
• Sulfuric Acid
• Thermal Power Plant releases radioactive materials as well as toxic metals such as lead and arsenic under normal operating conditions
• Carbon Monoxide is chiefly emitted by small engines typically used in lawn-mowers and chainsaws
• Gases that contribute to global warming are:

  • Methane
  • Water vapor
  • Carbon dioxide
  • Nitrous oxide
• Two pollutants that have to be present in order to form ozone are nitrogen oxide and hydrocarbons
• Ecological Solid Waste Management Act is also known as Republic Act 9003
• Climate change affects living organisms in various ways, except:

  • Wetland habitats will be increasingly impacted and further endanger biodiversity
  • Climate change increases ultraviolet (UV) radiation, with health impacts on humans and non-human animals
  • Climate change can create mismatches between the flowering timing of plants and the presence of pollinators
  • Climate change is increasing the reach of disease-carrying organisms such as mosquitoes
• If a waste is toxic, it means it is harmful or fatal when ingested or absorbed
• A lack of genetic diversity in a population or species is considered a problem because it reduces the ability of the population or species to adapt to a change in their habitat or to new diseases
• A report for selected actions that one expects to have a significant effect on the human environment is known as an Environmental Impact Statement
• Environmental Education is the process by which people develop awareness, knowledge, and concern of the environment in a sustainable manner for present and future generations
• Carbon dioxide is a type of greenhouse gas that is the biggest contributor, approximately 50%, to the greenhouse shield
• Republic Act No. 9275 is also known as the Clean Water Act, aiming to protect the country's water bodies from pollution of land-based sources
• The discharge of waste heat via energy dissipation into cooling water and subsequently into nearby waterways is known as thermal pollution or heat pollution
• One factor contributing to environmental impact is deforestation
• The Earth's atmospheric temperature is increasing causing widespread environmental changes due to the Greenhouse Effect
• A substance that dirties the air, water, or ground - thereby harming living organisms - is called a pollutant
• The major pollutant from automobile exhaust is NO (Nitrogen Oxide)
• A "habitat" is a particular area inhabited by plants and animals
• Deals with specific resources for humans to use rather than the management of the ecosystem itself is known as Natural Resource Management
• Halo-gen containing gases that when exposed to UV radiation from the sun will be converted into more reactive gases are Iodine, Bromine, Chlorine, and Fluorine
• A situation where two or more countries simultaneously impose the negative externality of pollution and suffer from that pollution is known as Regional Reciprocal Pollution
• Mercury is particularly hazardous to human health because it bio-accumulates high up the food chain
• Minerals found in the run-off from agricultural land and treated and untreated sewage effluents, which are highly responsible for eutrophication of water bodies, are Nitrogen and Phosphorus
• A free-living amoeba commonly found in the environment, especially in water and soil, that causes a disease known as Primary Amebic Meningoencephalitis is Naegleria Fowleri
• One possible cause of a Tsunami is an Earthquake
• Thermal pollution is the term used for the pollution and damage caused by the release of heated water into rivers and lakes that can harm animal and plant life
