Human Impact
This type of surface increases runoff and flooding in developed areas.
(specific word that means water cannot pass through it)
What is an impervious surface?
Photovoltaic panels convert this form of energy directly into electricity.
What is solar radiation or sunlight?
Species with narrow habitat tolerances are known as this.
What are specialist species?
This secondary pollutant forms when sunlight reacts with nitrogen oxides and VOCs. (hint: we usually add the word groundlevel)
What is ozone?
This effect causes dry conditions on the leeward side of mountains.
What is the rain shadow effect?
Spring fertilizer runoff commonly increases levels of this nutrient in streams.
What are nitrates or phosphates?
Wind turbines produce more electricity at greater heights because this increases with altitude.
What is wind speed?
This type of species shows rapid boom-and-bust population cycles.
What are r-selected species?
This atmospheric layer contains the densest air and most weather events.
What is the troposphere?
The protective ozone layer is primarily found in this atmospheric layer.
What is the stratosphere?
Adding this material to soil increases pH, helping to reduce soil acidity.
What is limestone?
This pollution-control device removes sulfur dioxide from coal plant emissions.
What is a wet scrubber?
Mangrove forests provide this regulating ecosystem service during storms.
What is flood protection or storm surge reduction?
New carpets commonly release these indoor air pollutants.
What are volatile organic compounds (VOCs)?
Climate change can weaken coral reefs when corals lose these symbiotic organisms.
Two parts: what is this event called and what is the symbiotic organism
What are algae?
This construction material helps reduce runoff in urban watersheds.
What is permeable pavement?
A city increased its recycling rate from 40% to 55%. This represents approximately this percent increase.
What is 37.5%?
This process causes toxins like methylmercury to increase at higher trophic levels.
What is biomagnification?
A country with a high total fertility rate and a decreasing death rate is likely in this demographic stage.
What is Stage 2 of the demographic transition?
When two species use different parts of the same resource to reduce competition, it is called this.
What is resource partitioning?
Wildlife bridges help reduce this negative effect of highways on animal populations. (think about the road separating a population)
What is habitat fragmentation?
A radioactive isotope has a half-life of 10 years. If a sample begins with 160 grams, approximately how much will remain after 30 years?
What is 20 grams?
Overuse of irrigation leads to this problem in soils.
Bonus: How can we reduce/prevent this issue?
What is soil salinization?
Bonus: Use water sensors to detect moisture levels and only water when needed versus on a schedule/to prevent over watering.
Using the Rule of 70, a country with a 1.5% growth rate will double in about this many years.
What is about 47 years?
A species adapted to survive in varying salinity levels is most likely found in this aquatic biome.
What is an estuary?
