Unit 1: Introduction, Ecology
Resources that can theoretically last forever are ______ resources
What is Renewable Resources
78% of the earth's atmosphere is made up of this element
This type of pollution comes from many different sources that are often difficult to identify
What is Nonpoint Source Pollution
These form when primary pollutants react with other primary pollutants or with naturally occurring substances such as water vapor
What are Secondary Pollutants
A naturally occurring, usually inorganic solid that has a characteristic chemical composition, an orderly physical structure, and a characteristic set of physical properties
What is a Mineral
The difference between this and causation is that it only identifies a possible relationship. The difference between this and causation is that it only identifies a possible relationship.
What is Correlation
This is the cool, rigid, outermost layer of the earth which consists of the crust and the rigid uppermost part of the mantle. It is 15-300 km thick
What is the Lithosphere
The amount of space between the particles that make up a rock, allowing rocks to hold water
What is Porosity
What are Chlorofluorocarbons or CFCs
The process of returning land to its original or better condition after mining is completed
What is Reclaimation
the rule of economics which states that the greater the demand for a limited supply of something, the more the thing is worth
What is the law of supply and demand
The small tectonic plate between North America and south america
What is the Cocos Plate
When the natural process of decaying plant matter in a body of water is sped up by inorganic nutrients and sewage entering the water system through human processes, speeding up oxygen depletion
What is Artificial Eutrophication
when temperatures fall below about -80 degrees C. these form from water and nitric acid
What are Polar Stratospheric Clouds
What are Mining Regulations
the probability of an unwanted outcome
what is Risk
The name of the location in the world on a tectonic plate boundary that contains nearly 75 percent of the world's active volcanoes that are on land
Where is The Ring of Fire
An often subtle form of pollution that decreases the amount of oxygen available in a body of water, leading to suffocation of aquatic species
What is Thermal Pollution
What is Formaldehyde
the contaminated water that results from the process of minerals/coal reacting with water and oxygen to form dilute sulfuric acid which dissolves toxic minerals that remain in mines and excess rock
What is Acid Mine Drainage (AMD)
the concept of using more than one system of knowledge to inform your scientific research and theories
what is Two-Eyed Seeing
The three important mechanisms responsible for transferring heat in the atmosphere
Radiation, conduction, and convection
What act introduced programs to protect groundwater and surface water from pollution and emphasized sound science and risk based standards for water quality?
What is the 1975 Safe Drinking Water Act
This is a machine used in cement factories and coal burning power plants to remove smoke particles from dust stacks by blowing gas through a container with an electrical current
What are Electostatic Precipitators
a series of long, inclined troughs used to wash through the sediments blasted from mountainsides with water during early day hydraulic mining in order to capture gold ore
What are sluices
