- 1Rift ValleyA valley formed where two pieces of a continent pull apart.
(Divergent plate boundary) - 2Sea floor spreadingOccurs at divergent plate boundary. New magma creates new sea floor and pushes old floor away
- 3Mid-ocean ridgeA ridge that is formed by magma at a divergent plate boundary.
- 4SubductionWhen two plates converge and one (the less dense one) goes under the other.
- 5Slab PullA subducting plate will pull the rest of its plate under with it
- 6Volcanic ArcsVolcanic arcs occur above a subduction zone where hot magma from the melting plate rises to the surface
- 7Hot SpotHot magma punched through the crust
- 8EarthquakeCaused by friction of plates running together
- 9LithificationThe process which sediments undergo to become a rock. They are compacted and cemented.
- 10CompactionSediments are squished by the weight of the sediments on top of them
- 11CementationSediments being glued together
- 12PressureUnderground there is lots of pressure because of the layers of rock
- 13MetamorphismThe act of a protolith undergoing heat and pressure to become a metamorphic rock.
- 14CleavageThe tendency for minerals to break on a certain plane
- 15Organic Sedimentary RockA rock formed of organic materials
- 16Clastic Sedimentary RockA rock made of sediments of other rocks
- 17ErosionAlways preceded by uplifting
- 18MaficRocks made of darker, heavier elements
- 19FelsicRocks made of elements that are lighter in color and weight
- 20Intrusive Igneous RocksRocks that are formed under the surface. Take longer to crystallize because of the heat, causing large crystals
- 21Extrusive igneous rocksFormed above the surface, causing quick cooling and small crystals
- 22RegionalMetamorphosed by the general heat and pressure of being underground
- 23ContactMetamorphosed by coming into contact or near contact to magma.
- 24FoliatedMetamorphic rocks with distinct layers
- 25ProtolithThe rock that becomes a metamorphic rock.
- 26Normal FaultOver hanging wall slides down
Caused by tensional stress - 27Reverse faultOverhanging wall goes up
Caused by compressional stress - 28Strike-Slip FaultRocks slide sideways passed each other
Cause by shear stress - 29Index FossilsFossils that are widespread and only lived for a short period of time
- 30Direct lightDirect light has more energy than indirect and causes higher temperatures
- 31Indirect lightEnergy is spread out, lower temperatures
- 32EvaporationAbsorbing heat=molecules absorbing energy
Cools surrounding liquid - 33CondensationHeat released
Warms surroundings - 34SublimationFrom ice to air
- 35DepositionFrom vapor to ice
- 36Air PressureAir Pressure up=Temperature up
Pressure down=temperature down - 37CLoudsliquid water molecules that have condensed on particles in the air
- 38Condensation Nucleiparticles in the air for water vapor to condense on
- 39Relative humidityThe % of available energy available to do the work of evaporation.
Num water vapor denom temp:
50/100=50% 50/200=25% 50/50=100%
50/100=50% 75/100=75% 30/100=30% - 40DewpointThe temperature where condensation begins. High dewpoint= moist air because the water vapor has to heat more to condense. Low dewpoint= dry air because the air has too heat less in order dry out
