axis
consistent with evidence
plausible
a region throughout which the same standard time is used. ( There are 24 time zones in the world at approximately by meridians at 15 degree intervals, an hour apart)
time zone
an imaginary circle that divides Earth into two halves called the Northern Hemisphere and the Southern Hemisphere
equator
one half of a sphere
hemisphere
a complete circle made by a planet around a sun or by a moon around a planet (orbit)
orbit/ revolution
to spin or turn around an axis
rotate/ rotation
to travel around another object in a circular or elliptical path
revolve
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
crescent Moon
the phase of the Moon that occurs about 14 days after the new Moon is visible from Earth’s surface & appears as a full circle
full Moon
the phase of the Moon, occurring about seven days after the new Moon, in which the lighted part of the moon that is visible from Earth’s surface is a half circle.
first quarter Moon
a phase of the Moon before or after it is full, when more than half of its disk is illuminated
gibbous Moon
