PRAXIS 5005: Science || QUESTIONS WITH CORRECT
SOLUTIONS!!
Igneous Rock correct answers 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 correct answers 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 correct answers Has been changed by great heat and pressure
altered, partially remelted
ex: slate, marble
Plate tectonic theory correct answers Lithosphere is made up of major and minor plates
Sit on viscous (thick fluid) part and move with it
Three types of plate boundaires correct answers 1. 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 correct answers 78% nitrogen
21 % oxygen
List earths atmosphere layers in order from lowest to highest. correct answers Troposphere
Stratosphere
Mesosphere
Thermosphere
Exosphere
Moon phase: waxing correct answers Two weeks where the moon goes from a new moon to a
full moon
After a full moon the moon is correct answers Waning
What type of cells are animal and plant cells correct answers Eukaryotic
Eukaryotic cells have a correct answers Nucleus
, Mendels laws are the laws of correct answers Segregation (each parent contributes half) and
the law of independent assortment (traits are passed randomly)
Natural selection correct answers The theory developed by Darwin that traits help give a
species a survival advantage are passed on to generations
Heterotrophs correct answers feed off of a host
can only consume food/ cannot produce their own
the number of protons in the nucleus determines correct answers the atomic number of the
element
atoms with neutral charge have an atomic number that is equal to correct answers the number
of electrons
Atomic mass (A) correct answers total number of protons(Z) and neutrons(N) in the nucleus
A= Z+N
Boyle's law correct answers Gases contract when pressure is applied to them
If temp remains the same so will pressure and and volume ratio
Ideal gas law correct answers explains the properties of a gas under ideal pressure, volume,
and temperature conditions.
Conduction correct answers form of heat transfer that occurs at the molecular level
ex: pan on burner, handle isn't hot at first but then heat transfers
Convection correct answers heat transfer that occurs through the movement or circulation of
fluids
heat moves to cooler denser areas
ex: boiling water, ocean currents
Temperature correct answers the average kinetic energy of an objects particle
when heat increases so does kinetic energy
Heat capacity correct answers the amount of heat energy needed to raise the the temp of an
object
measured in joules
Potential energy correct answers the amount of energy an object has stored within itself
because of its position or orientation
Kinetic energy correct answers the 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
Friction correct answers a force that arises as a resistance to motion where two surfaces are in
contact.
