Pollution Sources
This type of pollution comes from one specific place like a pipe.
Point Source Pollution
This toxic metal in drinking water can damage the brain.
Lead
This type of precipitation is caused by air pollution
Acid Rain
This chemical helps plants grow but can pollute water
Fertilizer
The number of births per 1,000 people
Birth Rate
Rain washing oil and trash into storm drains is an example of this type of pollution.
Non-point source pollution
(Runoff)
This event releases large amounts of oil into water
oil spill
This gas is a major part of smog
Ozone
This Chemical kills pests but can harm water organisms
Pesticides
The number of deaths per 1,000 people
Death Rate
Name one real life example of a point source pollution
Factory pipe, Wastewater outlet, sewage drain
Too many nutrients in water can cause this rapid algae growth
Algae Bloom
What weather condition traps pollution near the ground
temperature inversion
Wastewater from homes and schools
Sewage
When a population grows faster and faster over time
Exponential growth
This process carries pollutants from land into rivers and lakes.
Runoff
Name one way polluted water can affect humans
Makes people sick, unsafe drinking water, skin irritation, etc.
How can air pollution end up in lakes
Acid Rain
Name two human activities that can cause water pollution
Farming, factories, littering, oil rigs, cars
When too many organisms compete for limited resources
overpopulation
Which type of pollution is harder to control: point source or nonpoint source? Why?
nonpoint source, it is harder to trace to origin
What condition can air pollution cause in humans
Asthma
Why is smog worse during a temperature inversion
Pollution gets trapped and cannot rise and spread out
Managing resources so they stay available for the future
sustainable use
How can overpopulation increase pollution
more people = more waste, runoff and resource use
