AIR POLLUTION
This chemical reaction occurs when nitrogen oxides and volatile organic compounds react with sunlight, creating a heavy, low-lying, smoky haze over cities like Los Angeles.
What is SMOG?
This term describes water pollution that comes from a single, easily identifiable location, such as a factory discharge pipe or an oil tanker leak.
what is POINT SOURCE POLLUTION?
Sound intensity or loudness is measured using this logarithmic unit, where continuous exposure to levels above 85 can cause permanent hearing damage.
What is a DECIBEL?
This atmospheric gas, primarily released by breathing and the combustion of fossil fuels, is the most abundant human-produced greenhouse gas driving current global warming.
What is CO2?
Clue: Formed from the compressed, decayed remains of ancient organisms over millions of years, these three main non-renewable energy resources currently power the global economy.
What are FOSSIL FUELS?
This specific type of pollution forms when sulfur dioxide and nitrogen oxides react with water vapor in the atmosphere, dropping $pH$ levels below 5.0 and damaging forests and aquatic ecosystems.
What is ACID RAIN?
This process occurs when fertilizers (nitrogen and phosphorus) run off into water bodies, causing rapid algae growth that blocks sunlight and eventually starves the ecosystem of oxygen.
what is EUTROPHICATION?
This term describes any unwanted, intrusive, or disturbing sound that interferes with the normal daily activities of humans or wildlife, such as heavy traffic or industrial machinery.
What is NOISE POLLUTION?
This scientific term describes a surface's reflectivity, where light-colored surfaces like glaciers have a high value, and dark-colored oceans or asphalt have a low value.
What is ALBEDO EFFECT?
This term describes using less energy to perform the exact same task, such as switching from old incandescent light bulbs to modern LED bulbs.
What is ENERGY EFFICIENCY?
While highly beneficial when located in the stratosphere to shield us from UV radiation, this secondary pollutant is highly toxic and corrosive when it forms at the ground level (troposphere).
What is OZONE or the OZONE LAYER?
Abbreviated as DO, this critical water-quality measurement indicates how much oxygen gas is dissolved in the water for aquatic organisms to breathe.
What is DISSOLVED OXYGEN?
This passive mitigation method uses tall, dense concrete or wooden structures along major highways to physically block and redirect vehicle sound waves away from residential neighborhoods.
What is SOUND WALLS or NOISE BARRIERS?
Earth's surface absorbs solar ultraviolet rays and re-emits them as this lower-energy, long-wave thermal radiation, which is easily captured by greenhouse gases.
What is INFRARED RADIATION?
This gaseous hydrocarbon fossil fuel is often called a "bridge fuel" because it releases roughly 50% less carbon dioxide than coal when burned to produce electricity.
What is NATURAL GAS?
First passed in 1963 and majorly strengthened in 1970 and 1990, this landmark U.S. federal law empowers the Environmental Protection Agency (EPA) to set strict limits on harmful air pollutants.
What is the CLEAN AIR ACT?
Caused by soil erosion, runoff, and construction sites, this physical pollutant clouds the water (increasing turbidity) and prevents underwater plants from performing photosynthesis.
What is SEDIMENT?
Noise pollution in urban forests severely disrupts this avian behavior, forcing birds to alter the pitch, volume, or timing of their songs to be heard over background traffic.
What is ACOUSTIC COMMUNICATION?
This self-reinforcing cycle occurs when rising temperatures melt Arctic permafrost, releasing trapped methane gas, which then traps more heat and accelerates warming further.
What is a POSITIVE FEEDBACK LOOP?
This renewable, organic energy source includes materials like wood, crops, and landfill waste, which can be burned for heat but require careful replanting to remain carbon-neutral.
What is BIOMASS?
This naturally occurring, radioactive gas is invisible and odorless, entering homes through foundation cracks from decaying uranium in the soil and acting as a leading cause of lung cancer.
What is RADON?
This heavy metal, often released from burning coal, undergoes bioaccumulation in aquatic food webs, reaching highly toxic concentrations in top predators like tuna and swordfish.
What is MERCURY?
In humans, chronic exposure to noise pollution triggers a fight-or-flight response, causing a physical spike in this cardiovascular health metric.
What is BLOOD PRESSURE?
Having an albedo rating of up to 0.90, this fresh, light-colored natural surface has the highest reflectivity of any substance on Earth.
What is FRESH SNOW?
Inside most thermal power plants, burning coal or natural gas is used to boil water, producing high-pressure steam that spins this large mechanical fan to generate electricity.
What is a TURBINE?
