GUIDE QUESTIONS AND CORRECT
ANSWERS
Exponential growth - ANSWER-a model of population growth in which a population
grows at a fixed rate per amount of time
logistic growth - ANSWER-a model of population growth in which population growth
slows as the population approaches the habitats carrying capacity
niche - ANSWER-the total set of biotic and abiotic resources a species uses within a
community
population - ANSWER-a group of individuals of a single species that lives in a specific
area
producer - ANSWER-an organism that lives by making organic molecules from
inorganic molecules and energy
asthenosphere - ANSWER-a layer of weak, warm rock that flows slowly over geologic
time
continental drift - ANSWER-the hypothesis that the worlds continents move slowly over
earth's surface
convergent boundaries - ANSWER-Places where tectonic plates are coming together
core - ANSWER-earth's innermost layer, which is mostly iron and includes the inner and
outer core
crust - ANSWER-earth's surface layer consisting of oceanic and continental crust
density - ANSWER-the amount of mass an object or material has compared to its
volume
Divergent boundaries - ANSWER-places where plates are pulling apart
earth science - ANSWER-the study of the history, structure, and natural processes of
planet earth
geology - ANSWER-the earth science that is concerned with the compostion and
structure of the earth's interior
, inner core - ANSWER-a solid sphere of hot metal, mostly iron, at the center of earth
lithosphere - ANSWER-earth's outermost structural layer, consisting of cool rigid rock
lower mantle - ANSWER-the lowest portion of mantle, a zone of rigid rock
magma - ANSWER-molten rock inside the earth
mantle - ANSWER-a layer of thick hot rock between the crust and core
midocean ridge - ANSWER-a global system of underwater mountains created by
Seafloor spreading
ocean trenches - ANSWER-long, deep, steep troughs in the Seafloor where an oceanic
plate sinks beneath an overlying plate
outer core - ANSWER-a shell of hot liquid metal beneath the mantle and above the
inner core
Plate tectonics - ANSWER-the theory that states that earth's lithosphere so divided into
larger plates that slowly move around the globe
Seafloor Spreading - ANSWER-the process by which new lithosphere is crated at
Midocean ridges as older lithosphere moves away
subduction - ANSWER-the sinking of oceanic lithosphere into the asthenosphere
subduction zone - ANSWER-the region where an oceanic plate sinks into the
asthenosphere at a convergent plate boundary
tectonic plates - ANSWER-separate pieces of lithosphere that move on top of the
asthenosphere
transform boundaries - ANSWER-places where tectonic plates slide along beside one
another as they move
asteroid - ANSWER-a small rocky body that orbits the sun
comet - ANSWER-a body composed of ice and dust that orbits the sun, usually in a very
eccentric orbit, and that casts a luminous tail when it is close to the sun
Full Moon - ANSWER-the phase of the moon when it's sunlit side is the side facing
earth
inner planets - ANSWER-the planets close to the sun: Mercury, Venus, Earth and Mars
