Final Flashcards
Greenhouse effect
Trapping of heat in the atmosphere by water vapor, carbon dioxide and CFCs
Nuclear fission
The splitting of an atom into two or more atoms
Bio magnification
The process of mercury passing through water, to fish, to people
Point bar
Part of the stream/river that is the inside of the curve that is slower
Cut bank
Outside curve that causes erosion
Mass wasting
Downslope movement of earth materials
Aquitard
Will not let water through (ex. Clay)
Point source
Discrete and confined ( pipes that empty into streams or rivers from industrial or municipal sites)
Sustainability
Ability to keep resources available the same in the future
Biodiversity
The total number of species or the main species encountered
Salt water intrusion
Fresh groundwater may be displaced by saltwater
Species
Group of individuals capable of interbreeding
Unconformities
Represent a gap in geologic record
Vadose zone
Zone or layer above the water table in which some water may be suspended
Epicenter
The point on the surface of earth directly above the hypocenter of an earthquake area or first motion
Peak oil production
The time when about half of oil on earth will have been extracted
S waves
Does not go through liquid
P wave
The castes wave it can move through liquid and solid materials
Cleavage
Breaks in to layers
Mercalli scale
Earthquake measured in amount of damage
Precursor event
Events that occur before an earthquake, flood or volcanic eruption
Why is iron recycled so frequently?
There’s a huge market for it
Surface mining is used more because…
It’s more economical
Energy consumption between 1970s and 1960s
Increased at a slower rate
Coal rank based on
Bto and temperature
Coal usage and the future
More is being used because there is more available
Why is methane hydrate a good fuel source
Because it is cleaner and more abundant
Volcanoes effect on the atomsphere
Can cause a year without summer
Eric the red
Was able to sail to Greenland because of the period of warming
Love canal
Where hazardous chemicals and waste were buried then a suburb was built on top of it
Magnitude vs. intensity
Magnitude reflects how much energy is released. Intensity is the amount of shaking
Viscosity of magma
Deals with
- Silicon content (affects how viscos magma is)
- Temperature
Magnitude and frequency
Inverse relationship… 1 goes up 1 goes down
Engineers purpose for looking at soil
How easy will it be to get rid of soil & build on it..
Geothermal energy
Thermal energy generated and stored in the earth
Radon gas comes from
The natural breakdown of uranium
Soft water is linked to
Heart disease
Vegetation and landslides
Vegetation has been used to limit the hazard of landslides
