Aice Marine Science Final Exam ACTUAL
Exam Questions and CORRECT Answers
hypothesis - CORRECT ANSWER- an explanation of an observation that can be tested
through experimentation
variable - CORRECT ANSWER- a condition in an experiment that can be controlled or
changed
theory - CORRECT ANSWER- a well-substantiated explanation of an aspect of the natural
world that has been repeatedly tested and confirmed through observation and experimentation
quantitative - CORRECT ANSWER- numerical data such as DO or salinity levels.
prediction - CORRECT ANSWER- a statement of the expected lab results in an experiment
based on the hypothesis being tested
independent variable - CORRECT ANSWER- the variable being changed in an experiment
dependent variable - CORRECT ANSWER- the variable being measured in an experiment
control group - CORRECT ANSWER- a group within an investigation that receives exactly
the same treatment as the experimental group with the exception of the variable being tested.
control variables - CORRECT ANSWER- variables that are not being tested but that must be
kept the same in case they affect the experiment.
buffer - CORRECT ANSWER- a solution which can maintain a relatively stable pH
,atom - CORRECT ANSWER- the smallest particle an element can be divided into an still be
the same substance.
element - CORRECT ANSWER- a substance that cannot be chemically broken down into a
simpler substance.
molecule - CORRECT ANSWER- a group of atoms covalently bonded together
solid - CORRECT ANSWER- atoms within this substance have the least kinetic energy and
the least space between other atoms.
liquid - CORRECT ANSWER- atoms within this substance have moderate kinetic energy
and a moderate space between other atoms.
gas - CORRECT ANSWER- atoms within this substance have the MOST kinetic energy and
the MOST space between other atoms.
water vapor - CORRECT ANSWER- an example of a substance with a high kinetic energy
proton - CORRECT ANSWER- a positively charged subatomic particle contained within the
nucleus of an atom
neutron - CORRECT ANSWER- a neutral subatomic particle contained within the nucleus of
an atom
electron - CORRECT ANSWER- a negatively charged subatomic particle that orbits the
nucleus of an atom
nucleus - CORRECT ANSWER- the positively charged central core of an atom made of
protons and neutrons
,shells - CORRECT ANSWER- each of a set of orbitals around the nucleus of an atom that
can be occupied by electrons
atomic number - CORRECT ANSWER- the number of protons contained within the nucleus
of an atom
bond - CORRECT ANSWER- a strong force of attraction holding atoms together in a
substance
covalent bond - CORRECT ANSWER- a chemical bond that involves the sharing of electron
pairs between atoms
ionic bond - CORRECT ANSWER- chemical bond that involves the attraction of two
oppositely charged ions
hydrogen bond - CORRECT ANSWER- a weak bond between two molecules due to the
electrostatic attraction between a hydrogen atom in one molecule and an atom of oxygen,
nitrogen, or fluorine in the other molecule
ion - CORRECT ANSWER- an atom or molecule that has lost or gained one or more
electrons creating an electrical charge
CaCO3 - CORRECT ANSWER- calcium carbonate
MgSO4 - CORRECT ANSWER- magnesium sulfate
shares electrons - CORRECT ANSWER- covalent bond
transfers electrons - CORRECT ANSWER- ionic bond
, hydrogen - CORRECT ANSWER- a ___ bond must break for boiling water to become water
vapor
covalent - CORRECT ANSWER- the ___ bond is the strongest, and requires the most energy
to be broken
double covalent bond - CORRECT ANSWER- occurs when two electrons are shared
between at least two, or more, atoms; i.e. CO2
oxygen atom - CORRECT ANSWER- this side of the water molecule attracts the most
electrons due to its larger size
hydrogen atoms - CORRECT ANSWER- this side of the water molecule mostly loses its
electron, leaving it with a net positive charge
universal solvent - CORRECT ANSWER- water, being cohesive and adhesive, has this
unique title
Salinity - CORRECT ANSWER- A measure of dissolved solids, such as salt, in seawater.
TDS - CORRECT ANSWER- Total dissolved solids
Decrease salinity - CORRECT ANSWER- Precipitation, runoff, melting glaciers
Increase salinity - CORRECT ANSWER- Evaporation, forming glaciers
Tropical cyclones - CORRECT ANSWER- These generate intense wave action that causes
mixing of the surface waters of the ocean and are a storm characterized by a LOW atmospheric
pressure
