Model
The imaginary line around which an object spins, rotates. Earth rotates around an axis that runs straight through Earth from North pole to the South pole.
Axis
Consistent with evidence
Plausible
To turn or spin on an axis
rotate
To turn or spin on an axis
Rotation
A region throughout which the same standered time is used
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. (The half Earth that is north of the equator is the Northern hemisphere; the half of Earth that is south of the equator is the Southern Hemisphere)
Hemisphere
Another term for revolution
Orbit
A complete circle made by a plant around a sun or by a moon around a planet
Revolution
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 Earths surface is less than a half-circle. They occur right after or right before the New moon
Crecent 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 from Earth’s surface and appears as a full circle
Full moon
The phase of the moon, occurring about 7 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
A phase of the moon before or after it is full, when more than half of its disk is illuminated.
Gibbous moon
The phase of the moon that occurs about 7 days after the full moon in which the lighted portion of the moon that is visible from Earth’s surface is a half-circle
Last quarter moon
The revolution of the moon around Earth that produces the changing phases of the moon One complete lunar cycle happens every 29.5 days.
Lunar cycle
The phases of the moon, occurring about 14 days after the full moon, in which none of the lighted portion of the moon is visible to Earth’s surface
New moon
The phases of the moon when the illuminated portion visible from Earth is decreasing
Waning
The phases of the moon when the illuminated portion visible from Earth is increasing.
Waxing
