Unit F- List A Flashcards
information gathered
data
an event related to hoe 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 around which and object spins , or rotates. Earth rotates around an axis that runs 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 earths surface is less than half-circle (crescent shape).Crescent moons occur right after and right before the New moon.
crescent moon
an imaginary circle that divides Earth in 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 lighted portion of the moon that is visible from Earths surface is half a circle.
first-quarter moon
the phase of the moon, occurring about 14 days after the new moon in which the complete lighted portion of the moon is visible from Earths 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 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 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 of the moon is visible from earths surface
New moon
a complete circle made by a planet around a 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
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 moon and new moon)
wanning
the phase 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 intervals, an hour apart.)
time zone
One half of a sphere. (The half of 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
