The moon moves _____ per day around the earth. 13.2 degrees
When the moon is in the same direction as the sun and above it or below it in the sky is called? New Moon

A pointed end of a crescent moon Cusps
Sunlight reflected from the earth to the moon and back again is called? Earthshine
90 degrees to the east from the sun in the sky is called? First quarter
The phase "as it increases between first quarter and full moon, is called? Waxing gibbous
Exactly 180 degrees away from the sun in the sky Full moon
The full moon that occurs mearest to the time of the autumnal equinox (September 21-23) in the Northern Hemisphere or the vernal equinox (March 21-23) in the Southern Hemispere Harvest moon
The full moon occurring one month after the harvest moon or the fields are clear of vegetation and hunters can more easily spot game animals at this time Hunter's moon
The decreasing phase of the moon, following a full moon, when the illuminated disk gradually diminishes to the third quarter Waning gibbous

What is another name for third quater? Last quarter
The phrase "between third quarter and new moon, is called? Waning crescent
An eclipse that occurs when the moon passes between the earth and the sun, blocking some or all of the sun's light to the earth at a given location Solar eclipse
An event where the direct (solar) or reflected (lunar) light from the sun as viewed by an observer at a given location is completely cut off by another astronomical body Total eclipse
An eclipse in which the face of the sun is never fully covered, as observed at a particular location Partial eclipse
An eclipse of the sun in which a narrow ring (annulus) of the sun's disk shows around the moon because the moon is too far from the earth to cover the sun's disk completely Annular eclipse
Bright pinpoints of light that appear briefly during a total solar eclipse as sunlight shines through valleys around the moon's edge Baily's beads
During a total solar eclipse, the effect produced by a single Baily's bead flash occurring along the thin remaining solar crescent at the limb of the moon Diamond ring effect
The darkening of the full moon when it passes into the earth's shadow Lunar eclipse
The naturalistic theory that the moon was once a planet in its own orbit around the sun but that the earth somehow deflected it into an orbit around the earth Capture Theory
A naturalistic theory of the origin of the moon suggesting that somehow the moon split away from the earth when the earth was still molten Fission Theory
The uniformitarian theory that all celestial objects, but especially those of the solar system, were formed by the gravitational accumulation of space dust Accretion Theory
A naturalistic theory for the origin of the moon that suggests the matter in the moon was once a part of the earth, but a collision with another celestial object ejected the matter coalesced and went into orbit around the earth as the moon Impact Theory
