Question: Find the correct vocabulary word for each definition.
Solution (explanation):
Remember the following concepts:
- A species is considered endangered if it is in danger of extinction throughout all or a significant portion of its range.
- Chlorofluorocarbons (CFCs) deplete Earth's atmospheric ozone layer, which blocks the sun's damaging ultraviolet rays. CFCs were widely used as refrigerant gases and as propellants in aerosol sprays.
- A watershed, also called a drainage basin or catchment, is an area drained by a river and its tributaries
- A nonrenewable resource is a natural resource that cannot be re-made or re-grown at a scale comparable to its consumption. Coal, petroleum, and natural gas are considered nonrenewable because they can not be replenished in a short period of time.
- Biofuel, is any fuel that is derived from biomass—that is, plant or algae material or animal waste. Biofuel is considered to be a source of renewable energy,
- The mission of EPA is to protect human health and the environment.
- Photochemical smog is a mixture of pollutants that are formed when nitrogen oxides and volatile organic compounds (VOCs) react to sunlight, creating a brown haze above cities.
- PM1 are air pollutants with a diameter of 1 micrometer or less. The vast majority of these particles are small enough to pass directly into the bloodstream and lead to cancer, cardiovascular disease, or dementia.
- Thermal pollution is usually associated with increases in water temperatures in a stream, lake, or ocean due to the discharge of heated water from industrial processes, such as the generation of electricity.
- Planting trees helps remove greenhouse gases. In fact, a global program of massive tree planting could wipe out two-thirds of the greenhouse gas emissions that humans have put into the atmosphere.
Answer: we can conclude that the correct answer is:
- Any living organism which is "in danger of extinction throughout all or a significant portion of its range": Organism in danger of extinction (endangered).
- This was formerly used as a refrigerant and as a propellant in aerosol cans. These chemicals damage the ozone layer of the Earth: CFCs
- This is an area drained by a river, stream, etc: a watershed.
- This is a natural substance that cannot be re-made, or-grown, or regenerated on a scale compared to its use: a nonrenewable resource
- This is a liquid fuel derived from plant materials: biofuel.
- This is done to regulate materials that enter the Earth's atmosphere due to any type of combustion: Planting trees.
- This is a governmental agency whose mission is to protect human health and the environment: EPA.
- This is a type of photochemical air pollution that is a result of the interaction of sunlight with certain chemicals in the atmosphere.
Photochemical smog: Photochemical smog.
- This type of air pollution is very hazardous to your health: PM1.
- This is a type of pollution associated with increases in water temperatures in a stream, lake, or ocean due to the discharge of heated water from industrial processes, such as the generation of electricity: Thermal pollution.
