Pollution Sources
This type of pollution comes from a single, identifiable source.
What is a point source?
This gas is the main contributor to global warming.
What is carbon dioxide?
This method reduces waste before it is created.
What is reduction?
This underground layer stores groundwater.
What is an aquifer?
This is the number of births in a population.
What is birth rate?
Runoff from farms and streets is an example of this type of pollution.
What is nonpoint source pollution?
These chemicals damage the ozone layer.
What are chlorofluorocarbons (CFCs)?
Using items again instead of throwing them away is called this.
What is reuse?
This practice helps maintain soil fertility by alternating crops.
What is crop rotation?
This type of growth increases rapidly over time.
What is exponential growth?
This type of source includes pollution from many scattered locations.
What is nonpoint source pollution?
A low pH level means water is this.
What is acidic?
Turning old materials into new products is called this.
What is recycling?
This is the careful use and protection of water resources.
What is water conservation?
This is the maximum population an environment can support.
What is carrying capacity?
A factory pipe dumping waste into a river is this type of source.
What is a point source?
This type of pollution often results from pesticide runoff.
What is water pollution?
This process uses microorganisms to break down organic waste.
What is composting?
Overgrazing leads to this major land problem.
What is soil erosion (or land degradation)?
When a population exceeds carrying capacity, this typically happens.
What is population decline (or resource depletion)?
This is the reason nonpoint sources are harder to control than point sources.
What is because they come from many widespread locations?
These gases combine with water vapor to form acid rain.
What are nitrogen oxides and sulfur dioxide?
This waste strategy has the greatest impact on conserving resources given a reason.
What is reduction, because it prevents waste and resource use from the start?
Name one method used to improve water management.
What is fixing leaks / efficient irrigation / water recycling?
Calculate: A population of 1,000 has 50 births. What is the birth rate?
What is 5%?
