nonliving, physical features of the
environment, including air, water,
sunlight, soil, temperature, and climate.
a type of erosion that occurs when
windblown sediments strike rocks and
sediments, polishing and pitting their
surface.
age, in years, of a rock or other object;
can be determined by using properties of
the atoms that make up materials.
measure of the amount of light a star
actually gives off.
flat seafloor area from 4,000 m to 6,000
m below the ocean surface, formed by the
deposition of sediments.
rate of change of velocity; can be
calculated by dividing the change in the
velocity by the time it takes the change
to occur.
precipitation with a pH below 5.6—which
occurs when air pollutants from the
burning of fossil fuels react with water
in the atmosphere to form strong acids
that can pollute water, kill fish and
plants, and damage soils.
acidic moisture, with a pH below 5.6,
that falls to Earth as rain or snow and
can damage forests, harm organisms, and
corrode structures.
substance with a pH lower than 7.
the study of sound.
long-lasting immunity that results when
the body makes its own antibodies in
response to a specific antigen.
energy-requiring process in which
transport proteins bind with particles
and move them through a cell membrane.
any structural or behavioral change that
helps an organism survive in its
particular environment.
any organism that uses oxygen for
respiration.
forceful behavior, such as fighting, used
by an animal to control or dominate
another animal in order to protect their
young, defend territory, or get food.
large body of air that has the same
characteristics of temperature and
moisture content as the part of Earth’s
surface over which it formed.

compound, such as ethanol, that is formed
when 2OH groups replace one or more
hydrogen atoms in a hydrocarbon.
chlorophyll-containing, plantlike
protists that produce oxygen as a result
of photosynthesis.
an alternate form that a gene may have
for a single trait; can be dominant or
recessive.
substance that causes an allergic
reaction.
overly strong reaction of the immune
system to a foreign substance.
different forms of the same element
having different molecular structures.
a mixture of elements that has metallic
properties.
particle consisting of two protons and
two neutrons that is emitted from a
decaying atomic nucleus.
electric current that reverses its
direction of flow in a regular pattern.
tiny, thin-walled, grapelike clusters at
the end of each bronchiole that are
surrounded by capillaries; carbon dioxide
and oxygen exchange takes place.
building block of protein.
thin, liquid-filled, protective membrane
that forms around the embryo.
egg covered with a shell that provides a
complete environment for the embryo’s
development; for reptiles, a major
adaptation for living on land.
a measure of the energy carried by a
wave.
any organism that is able to live without
oxygen.
flowering vascular plants that produce
fruits containing one or more seeds;
monocots and dicots.
chemicals produced by some bacteria that
are used to limit the growth of other
bacteria.
a protein made in response to a specific
antigen that can attach to the antigen
and cause it to be useless.
any complex molecule that is foreign to
your body.

measure of the amount of light from a
star that is received on Earth.
jointed structures of arthropods, such as
legs, wings, or antennae.
layer of permeable rock that allows water
to flow through.
blood vessel that carries blood away from
the heart, and has thick, elastic walls
made of connective tissue and smooth
muscle tissue.
a type of reproduction—fission, budding,
and regeneration—in which a new organism
is produced from one organism and has DNA
identical to the parent organism.
a piece of rock or metal made up of
material similar to that which formed the
planets; mostly found in the asteroid
belt between the orbits of Mars and
Jupiter.
plasticlike layer of Earth on which the
lithospheric plates float and move
around.
lung disorder in which the bronchial
tubes contract quickly and cause
shortness of breath, wheezing, or
coughing; may occur as an allergic
reaction.
air surrounding Earth; is made up of
gases, including 78 percent nitrogen, 21
percent oxygen, and 0.03 percent carbon
dioxide.
the smallest particle of an element that
still retains the properties of the
element.
tiny building block of matter, made up of
protons, neutrons, and electrons.
number of protons in an atom’s nucleus.
two upper chambers of the heart that
contract at the same time during a
heartbeat.
plant hormone that causes plant leaves
and stems to exhibit positive
phototropisms.
weighted-average mass of the mixture of
an element’s isotopes.
total distance an object travels divided
by the total time it takes to travel that
distance.
axis
axon
imaginary vertical line that cuts through
the center of Earth and around which
Earth spins.
neuron structure that carries messages
away from the cell body.
