PRAXIS 5005. Science
Igneous Rock - answer formed when hot magma cools beneath the ground
or
lava cools above the ground
forms crystal like/ glassy rocks
ex: granite, pumus, basalt
Sedimentary Rock - answer Changed by pressure
does not involve heat
Usually near water/ involves water
sometimes contain fossils
forms from previously weathered and erroted material which may have been igneous,
sedimentary, rock metamorphic rock.
ex: dolemite, limestone, sandstone
Metamorphic Rock - answerHas been changed by great heat and pressure
altered, partially remelted
ex: slate, marble
Plate tectonic theory - answerLithosphere is made up of major and minor plates
Sit on viscous (thick fluid) part and move with it
Three types of plate boundaires - answer1. Transform boundaries: they slide past each
other causing friction/ earthquakes
2. Divergent boundaries: two plates that pull away from each other/ creates new crust
3. Convergent boundaries: plates push into each other/ one goes under called
subduction
The atmosphere is composed of - answer78% nitrogen
21 % oxygen
List earths atmosphere layers in order from lowest to highest. - answerTroposphere
Stratosphere
Mesosphere
Thermosphere
Exosphere
Moon phase: waxing - answerTwo weeks where the moon goes from a new moon to a
full moon
, After a full moon the moon is - answerWaning
What type of cells are animal and plant cells - answerEukaryotic
Eukaryotic cells have a - answerNucleus
Mendels laws are the laws of - answerSegregation (each parent contributes half) and
the law of independent assortment (traits are passed randomly)
Natural selection - answerThe theory developed by Darwin that traits help give a
species a survival advantage are passed on to generations
Heterotrophs - answerfeed off of a host
can only consume food/ cannot produce their own
the number of protons in the nucleus determines - answerthe atomic number of the
element
atoms with neutral charge have an atomic number that is equal to - answerthe number
of electrons
Atomic mass (A) - answertotal number of protons(Z) and neutrons(N) in the nucleus
A= Z+N
Boyle's law - answerGases contract when pressure is applied to them
If temp remains the same so will pressure and and volume ratio
Ideal gas law - answerexplains the properties of a gas under ideal pressure, volume,
and temperature conditions.
Conduction - answerform of heat transfer that occurs at the molecular level
ex: pan on burner, handle isn't hot at first but then heat transfers
Convection - answerheat transfer that occurs through the movement or circulation of
fluids
heat moves to cooler denser areas
ex: boiling water, ocean currents
Temperature - answerthe average kinetic energy of an objects particle
when heat increases so does kinetic energy
Heat capacity - answerthe amount of heat energy needed to raise the the temp of an
object
measured in joules
