Two times of year when the day and night lengths are about 12 hours. Equal day and night.

This occurs in March and marks the beginning of spring in North America. Also called spring equinox

This occurs in September and marks the beginning of fall in North America. Also called fall equinox

Two times of year when the day or night lengths are at their longest or shortest. The Earth is either tilted towards or away from the sun at 23.5 degrees

This occurs in December and marks the beginning of winter in the Northern Hemisphere. This is also the shortest day of the year in the NH

This occurs in June and marks the beginning of summer in the Northern Hemisphere. This is also the longest day of the year in the NH

Because the year has 365 1/4 days a year we add on day to the calendar every four years we call this ______.

the phase of the moon in which we see the entire moon lighted, and it appears bright and round

The phase of the moon when it is three-quarters of the way through its orbit, and we see half of the moon lighted

the phase of the moon in which only a curved edge of the moon's side that faced earth is illuminated, lasts about 6 days, can be a small sliver or almost a quarter moon.

when the size of the illuminated portion of the moon is greater than half but not a full moon, lasts about 6 days can be almost all white or just a little more than 1/2 white
