Information gathered
data
an event related to how the world and universe work.
phenomenon
any representation of a system
model
the imaginary line around which an object spins, or rotates. Earth rotates around an axis that runs straight through earth from the north pole to south pole
axis
the phase of the moon in which the lit portion of the moon visible from earths surface is less than a half-circle (crescent shape). Crescent Moons occur right after and right before the new moon.
crescent Moon
an imaginary circle that divides earth into two halves called the Northern Hemisphere and the southern Hemisphere.
equator
the phases of the moon, occurring about seven days after the new moon, in which the lighted portion of the moon that is visible to earths surface is a half-circle
first-quarter moon
the phase of the moon that occurs about 14 days after the new moon in which the complete lighted portion of the moon is visible to earths surface and appears as a full circle
full moon
a phase of the moon before or after the full, when more than half of its disk is illuminated
gibbous moon
the phase of the moon that occurs about seven days after the full moon in which the lighted portion of the moon is visible to earths surface is a half circle
last quarter moon
the revolution of the moon around the earth that produces the changing phases of the moon. one complete lunar cycle takes about 29.5 days.
lunar cycle
the phase of the moon, occurring about 14 days after the full moon, in which none of the lighted portion is visible to earths surface.
new moon
a complete circle made by a planet around the sun or by a moon around a planet
orbit/revolution
consistent with evidence
plausible
to travel around another object in a circular or elliptical path
revolve
