Geology chpt 2 & 8

What are the subatomic particles and their charges? nuetrons (neutral) , electrons (negative), protons (positive)
what is ionic bonding? positively charged ions bond with negatively charged atoms in an attempt to get 8 electrons in their out shell.
why ions are created? created to bond together with other ions to complete the outer shell. either have a surplus of electrons (anion) negative charged. or have a deficit (cation) postive charge.
Most abundant elements in earths crust? oxygen 47% , silicon 28% , sodium, calcium, potasium, iron, aluminum, and magnesium
Si? silicon 28% of earths crust (2nd most element of earths crust)
Na? sodium
Ca? calcium
K? Potasium
Fe? Iron
Al? Aluminum
Mg Magnesium
O? oxygen (47%) of earths crust (most abundant element)
S(-2) Sulfide (mineral pyrite)
O(-2) oxide (mineral hematite)
SO4(-2) Sulfate (mineral gypsum)
CO3(-2) carbonate (mineral calcite)
SiO4(-2) silicate (mineral quartz)
What is uniformatianism and how it used in geology? features of earth can be explained by present day processes. Present is the key to the past. compare the past results with modern day results if they are the same then they mustve had the same process.
OH (original horizontally) sediments begin as horizontal layers that are essentially parallel to earths surface.
Super Position Sequence of layers, oldest at the bottom, youngest at the top
Cross Cutting Anything that cuts a sequence of rock is younger then the sequence it cuts.
Correlation age relationships between two units at different locations. (fayetville bentonville example) if one fossil is found on layer one in bentonville and that same fossil is found in layer 4 in fayetville then those two layers are the same.
The 3 eras of the geologic time scale? oldest is precambrian, after that the three main are Paleozoic, Mesozoic, Cenozoic
Periods in Paleozoic? 7 Cambrian, Ordovician, Silurian, Devonian, Missisipian, Pennsylvanian, permian
Periods in Mesozoic? 3 Triassic, Jurassic, Cretaceous
Periods in Cenozoic 3 Paleogene, Neogene, Quaternarny
Come Over Some Day, Maybe Play Poker? Try Jeffs Crazy Pizza, Nacho Queso? Cambrian, Ordovician, Silurian, Devonian, Mississipian, Pennslyvanian, permian, Triasssic, Jurrasic, Cretacous, Paleogene, Neogene, Quaternary
