15 Cards in this Set

  • Front
  • Back
allopatric speciation
new species from isolation of a small population that becomes genetically distince from its parent species
phyletic gradualism
slow accumulation of minor changes bringing about a trasition from a parent species to its descendant species
puctuated equilibrium
rapid bursts of change followed by long periods of little or no change
convergent evolution
similar morphology developed by distantly-related groups; usually by adaptation to similar environments
parallel evolution
aka iterative evolution
similar morphology developed by closely-related groups
NAME the evolutionary trends
increasing/decreasing size
reduction in number
increasing complexity
mosaic evolution
different rates of change for different body parts
--archaeopteryx (bird; gets feathers but still a dinosaur)
living fossils
groups exhibiting little change
declination and inclination of polar bar in center of Earth; responsible for the reversed polarity of earth (apparent polar wandering)
NAME the seven major plates and seven minor plates
MAJOR PLATES: North America, South America, Indian, Australian, Eurasian, African, Antarctic
MINOR PLATES: Nazca, Cocos, Juan de Fuca, Philippine, Arabian, Caribbean, Scotian
NAME the types of plate motion (three)
1. divergent (seafloor spreading/normal faults)
2. convergent (subduction/thrust faults)
3. lateral (transform/strike-slip faults)
movement of chemical materials from one reservoir to another
--source (origional reservoir)
--sink (recieving reservoir)
1st Order Cycle
1. water evaporates from ocean into atmosphere
2. atmosphere moves water over land
3. precipitation occurs: water into glacier/ groundwater/lakes and streams/land plant reservoirs
4. water returned to ocean by rivers/groundwater flow
2nd Order Cycle
1. water transpires from land plants/evaporates from lakes and rivers into atmosphere
2. precipitation on ocean and land
--> interacts with rock cycle!!!
chemcially reacts with igneous and metamporhic rocks= creates sediments!
water erodes/transfers sediments (that are created)!
Photosynthesis-Respiration Cycle
CO2 + H20 + inorganic N and P + SUNLIGHT = CH20 + inorganic compounds of N and P + O2

CH2O + inorganic compounds with N and P + O2 = CO2 + H2O + inorganic N and P + ENERGY (for metabolism)
