axis
the imaginary line around which an object spins or rotates around and axis that runs straight through earth from the north pole to the south pole.
plausible
consistent with evidence
rotate

time zone
a region throughout which the same standard time is used (there are 24 time zones in the world at approximately by meridians at 15 degrees intervals, an hour apart)
angle
the space usually measured in degrees between two interesting lines or surfaces at or close to the point where they meet.
equator

hemisphere

crescent Moon
The phase of the Moon in which the lit portion of the Moon visible from Earth’s surface is less than a half-circle (crescent shape).Crescent moons occur right after and right before the new moon
full moon
the phase of the moon that occurs about 14 days after the new moon in which the lighted portion of the moon that is visible from earth’s surface is a half-circle.
first quarter moon
the phase of the moon, occurring about seven days after the new moon, in which the lighted portion of the moon that is visible from Earth’s surface is a half-circle.
gibbous moon
a phase of the moon before or after it is full, when more than half of its disk is illuminated
last-quarter moon
the phase of the moon that occurrs about 7 days after the full moon in which the lighted portion of the moon that is visible from earth’s is a half circle
lunar cycle
the revolution of the moon around earth that produces the changing phases of the moon. One complete lunar cycle takes about 29.5 days.
new moon
the phase of the moon, occurring about 14 days after the full moon, in which none of the lighted portion of the moon is visible from earth’s surface.
waning
the phases of the moon when the illuminated portion visible from earth is decreasing (between the full and new moon)
waxing
the phases of the moon when the illuminated portion visible from earth is increasing (between the new full moon).
