Q

Rate of Natural Increase

A

a measure of population growth that considers births and deaths within a population

A higher rate of natural increase implies faster population growth, while a lower rate suggests slower growth or even a decrease in population size.

Q

Density - Dependent Factors

A

affect the population stability based on density,
when it gets high, predation is needed as a factor that is affected by density when it;s high we do well, but when it’s low density predators starve

ex. diseases, pandemics

21
Q

Anthracite

A

mine
deep shaft mining
a mile or more into earth
oldest and purest
burns the hottest

22
Q

Bituminous Coal

A

not the deepest just above anthracite.
easily extracted
most used
dirtiest
very dark

23
Q

Lignite Coal

A

brown
soft
wetter then bituminous not as wet as peat

24
Q

Black Lung Disease

A

associated w/ anthracite or deep shaft mining operations.
the small particles block the ability for gases to exchange across the cardiovascular system to the breathing.
common in miners.
will lead to cancer.
under osha, miners are to wear PPE mask

25
Q

Strip Mining

A

bituminous, most popular

26
Q

Subsurface Mining

A

deep into earth
anthracite
lignite

27
Q

Acid Deposition

A

occurs when large amount of sulfur dioxide is released in the atmosphere when coal is burning.
when breathing a high dose it can be deadly to the lungs.

28
Q

Scrubbers

A

devices that help clean pollutants and harmful chemicals from industrial emissions or smokestacks to reduce air pollution

29
Q

Crude Oil

A

comes from microscopic- plankton.
they have oil and when they die they settle to the bottom of the ocean creating sedimentation creating crude oil; natural gas,
comes from green organisms.

30
Q

Fission

A

Splitting uranium 235 and capturing the energy to boil water to create steam, and turn electrical power

Chain reaction
splitting of an atomic nucleus into two smaller fragments followed by the release of a large amount of energy,

31
Q

Fusion

A

uses the lightest element on earth; hydrogen fussed together to create helium in a fusion reactor which is 4 times more energetic

Joining of two lightweight atomic nuclei
Fuel = isotopes of hydrogen pros:
No high level waste
fuel is hydrogen
cons:
Takes high temps.
confines plasme

32
Q

Enrichment

A

purifying and enriching uranium to increase the concentration of U235

33
Q

Control Rod

A

used to regulate rate of fission
if pushed down the process is slowed, less electrical power, if pulled up it speed the process

90 control rods must be kept at all times

34
Q

Hydropower

A

Form of renewable energy reliant on flowing or falling water to generate mechanical energy or electricity
if the equalizer allows it to run….
can destruct the ecosystems
silk can build up at the bottom and block the system.

35
Q

Chernobyl

A

many mistakes:
Human error
water and steam instead of graphite moderator
did not use a containment top
in ukraine
1986

36
Q

High Level Radioactive Waste

A

nuclear waste in nuclear weapon, or power facilites

37
Q

Low Level Radioactive Waste

A

nuclear waste from research labs, unis, hospitals

38
Q

Active Solar Heating

A

how to het water heater
black shield on the roof that facing south orientation but rather than creating electricity they have tubes within them that water flows through like a radiator and when the sun hits the shield the tubes hits the water and has other f=devices that increase the flow.

merely heating water, fluids or air mass

39
Q

Passive Solar Heating

A

heating greenhouses, pools or sun houses
energy is penetrating into the water of the pool or into the greenhouse and keeping it warm because it can’t radiate back out or it gets trapped.

40
Q

Solar Thermal Heating/ Electric Generation

A

generates electricity from the heat of the sun

special systems are used to focus sunlight and create steam which drives turbines to produce electricity

41
Q

Photovoltaic

A

generates electrical current
shields are semiconductors so when the energy of the sun hits the material
photovoltaic shields excites the electrons which causes a flow of electricity and the flow generates the power for the system.

42
Q

Fuel Cell

A

a battery that generates electricity by combining hydrogen and oxygen.

produces electricity w/o burning fuel

env. friendly

43
Q

Wind Power

A

common in mountain passes
North Sea Area
needs a lot of space
and can be disruptive to the ecosystem
kills large birds of prey

44
Q

Biomass Methane

A

found in landfills where the trash and organic materials buried become anaerobic and produces methane gas used to power electricity sent to the power grid.

45
Q

Geothermal

A

practical in areas where there in molten material and there is core that is near water. ground water systems below being heated.
geothermal water is very toxic

46
Q

Biomass (alcohol)

A

the alcohol is ethenyl, mainly in the USA and made out of corn.
used for fuel

47
Q

Age Distibution Curves

A

number in millions, age and sex

shows how a population is spread out in terms of different age groups.

48
Q

Kerosene

A

1850 pan oil in the US; main source of fuel from crude oil; kerosene used for lights.

49
Q

Peat

A

made out of decayed plant material and is can be used as fuel or in gardening

forms in waterlogged areas like swamps

50
Q

Reserve

A

a material that can be extracted profitably with existing technology under present economic conditions
what you’re willing to buy within your affordability

51
Q

Resource

A

all of the resources from a substance that can be extract and processed that can be sold to consumers willing to buy.

52
Q

Sulfur Dioxide

A

a gas produced when things like coal and oil are burn
harmful to the environment and human health
causes acid rain
