Apes

Front 1

Ionizing radiation

1

Back 1

enough energy to knock electrons from atoms forming ions, capable of causing cancer (ex gamma-Xrays-UV)

Front 2

High Quality Energy

2

Back 2

organized & concentrated, can perform useful work (ex fossil fuel & nuclear)

Front 3

Low Quality Energy

3

Back 3

disorganized, dispersed (heat in ocean or air wind, solar)

Front 4

First Law of Thermodynamics


4

Back 4

energy is neither created nor destroyed, but may be converted from one form to another

Front 5

Second Law of Thermodynamics

5

Back 5

when energy is changed from one form to another, some useful energy is always degraded into lower quality energy (usually heat)

Front 6

Natural radioactive decay

6

Back 6

unstable radioisotopes decay releasing gamma rays, alpha & beta particles

Front 7

Half life

7

Back 7

the time it takes for ½ the mass of a radioisotope to decay

Front 8

Estimate of how long a radioactive isotope must be stored until it decays to a safe level
8

Back 8

approximately 10 half-lives

Front 9

Nuclear Fission

9

Back 9

nuclei of isotopes split apart when struck by neutrons

Front 10

Nuclear Fusion

10

Back 10

2 isotopes of light elements (H) forced together at high temperatures till they fuse to form a heavier nucleus. Expensive, break even point not reached yet

Front 11

Ore

11

Back 11

a rock that contains a large enough concentration of a mineral making it profitable to mine

Front 12

Organic fertilizer

12

Back 12

low acting & long lasting because the organic remains need time to be decomposed

Front 13

Best solution to Energy shortage

14

Back 13

onservation and increase efficiency

Front 14

Surface mining


14

Back 14

cheaper & can remove more mineral, less hazardous to workers

Front 15

Hummus

15

Back 15

organic, dark material remaining after decomposition by microorganisms
