Starry Starry Night By: Angie Bowen
Rotation VS Revolution Revolution A complete trip of the Earth around the sun. This takes the Earth one year. Rotation A complete turn of the Earth on its axis from west to east. This takes the Earth one day.
Question • What causes day and night? • (a) the Earth’s orbit • (b) the Earth’s rotation • (c) the Sun’s orbit • (d) the moon’s orbit
Answer (b) the Earth’s rotation
Question • It takes Earth how long to complete one revolution? • (a) 24 hours • (b) one month • (c) one year • (d) it depends on the season

Earth’sSeasons The Earth's seasons are not caused by the differences in the distance from the Sun throughout the year (these differences are extremely small). The seasons are the result of the tilt of the Earth's axis. Summer is warmer than winter (in each hemisphere) because the Sun's rays hit the Earth at a more direct angle during summer than during winter and also because the days are much longer than the nights during the summer. During the winter, the Sun's rays hit the Earth at an extreme angle, and the days are very short. These effects are due to the tilt of the Earth's axis.
Solstice The solstices are days when the Sun reaches its farthest northern and southern declinations. The winter solstice occurs on December 21 or 22 and marks the beginning of winter (this is the shortest day of the year). The summer solstice occurs on June 21 and marks the beginning of summer (this is the longest day of the year).
Equinox Equinoxes are days in which day and night are of equal duration. The two yearly equinoxes occur when the Sun crosses the celestial equator. The Spring equinox occurs in late March (this is the beginning of spring in the Northern Hemisphere and the beginning of fall in the Southern Hemisphere); the autumn equinox occurs in late September (this is the beginning of fall in the Northern Hemisphere and the beginning of spring in the Southern Hemisphere).
Question • Summer occurs on Earth in the northern hemisphere when: • the northern hemisphere is tilted away from the Sun • the northern hemisphere is tilted towards the Sun • (c) the Earth is revolving closest to the Sun • (d) none of these are true
Answer • (b) the northern hemisphere is tilted towards the Sun
Question True or False: The equinoxes occur during Fall and Spring? (a) True (b) False
Answer (a) True
Question What is the cause of Earth’s seasons? (a) the distance of Earth from the Sun (b) the position of the moon (c) Earth’s axial tilt (d) Earth’s orbit
Answer (c) Earth’s axial tilt
Question Which has more daylight hours in the northern hemisphere? (a)March 20 (b) June 20 (c) September 21 (d) December21
Answer (b) June 20

OurMoon During the waning crescent moon phase, we see a small sliver of light on the ______________ side of the moon. (a) right (b) left
Answer (b) left
Question Which phase of the moon occurs directly AFTER the new moon? (a) waxing crescent (b) waning crescent (c) waxing gibbous (d) waning gibbous
Answer (a) waxing crescent
Did You Know……? We only see one side of the moon. It turns out that the speed at which the Moon rotates has led to this particular phenomenon. Millions of years ago, the Moon spun at a much faster pace than it does now. However, the gravitational influence of the Earth has gradually acted upon the Moon to slow its rotation down. The Moon’s rotational period now matches its revolution – about 29.5 days – and it is now "locked in" to this period.
Question Why do we only see one side of the moon? • the Earth’s and moon’s revolution times are the same • the Earth’s rotation and revolution times are the same (c) the moon’s rotation and revolution times are the same (d) the Earth’s and moon’s rotation times are the same
Answer • (c) the moon’s rotation and revolution times are the same
