PRAXIS 5005: SCIENCE QUESTIONS &
ANSWERS(RATED A+)
Igneous Rock - ANSWERformed when hot magma cools beneath the ground
or
lava cools above the ground
forms crystal like/ glassy rocks
ex: granite, pumus, basalt
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
Sedimentary Rock - ANSWERChanged 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
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
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
Potential energy - ANSWERthe amount of energy an object has stored within itself
because of its position or orientation
Kinetic energy - ANSWERthe energy of an object in motion
when an object is dropped it converts from potential energy to kinetic energy
you can use potential and kinetic energy to calculate velocity of an object during a
fall
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
