Unit F-List A Flashcards
Information gathered.
Data
An event related to how the world and universe work.
Phenomenon
Any representation of a system, or it’s components, to help one study and understand how it works.
Model
The imaginary line around which an object spins, or rotates. Earth rotates around an axis that run straight through Earth from the North Pole to the South Pole.
axis
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
An imaginary circle that divides Earth into two halves called the Northern Hemisphere and Southern Hemisphere.
Equator
The phase of the Moon,occurring about seven days after the new Moon, in which the complete lighted portion of the moon that is visible from Earth’s 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 from Earth’s surface & appears as a full circle.
Full Moon
A phase of the Moon before or after it is full, when more than half of it’s disk is illuminated.
Gibbous Moon
The phase of the Moon that occurs about 7 days after the full Moon in which 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.
Lunar cycle
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.
New Moon
Another term of revolution.
Orbit
Consistent with evidence.
Plausible
A complete circle made by a planet around the sun or by a moon around a planet (orbit).
revolution
To travel around another object in a circular or elliptical path.
Revolve
To turn or spin around an axis.
Rotate, Rotation
The phases of the Moon when the illuminated portion visible from Earth is decreasing (between the full and new Moon).
Waning
The phases of the Moon when the illuminated portion visible from Earth is increasing (between the new full Moon.
Waxing
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.)
Time zone
One half of a sphere.
Hemisphere
