Phases of the Moon Reasons for the Seasons Constellations Eclipses Celestial Sphere Using terms $200 $200 $200 $200 $200 $200 $400 $400 $400 $400 $400 $400 $600 $600 $600 $600 $600 $600 $800 $800 $800 $800 $800 $800 $1000 $1000 $1000 $1000 $1000 $1000 $200 Full moon Which phase appears as the moon completely lit overhead at midnight $400 6 pm If the moon rose tonight at 5 pm, about what time will it rise tomorrow $600 Full moon a lunar eclipse occurs only during a $800 The Earth is also revolving around the Sun, so the Moon must catch up Why is there a difference between the sidereal and lunar months? $1000 The phase will be full because it is rising opposite the sun. If the moon is directly opposite of the sun in the sky it will be a full moon If the moon rises at sunset, what phase will it be in? Why? $200 23.5 degrees What is the tilt of the earth on its axis? $400 year The time it takes for Earth to complete an orbit around the Sun is called. $600 equinoxes The places where the Sun crosses the equator are called the $800 Summer solstice The sun is high overhead at 23.5 degrees north. $1000 Check your answer with me Draw the reasons for the seasons showing equinoxes and solstices $200 constellations Groups of stars making an apparent pattern in the celestial sphere are called $400 Brightest star In general, what is true of the alpha star in a constellation $600 About 3000 About how many stars are visible on a clear, dark night with the naked eye alone? $800 Taurus If the sun rises in the constellation of Taurus which constellation will it set in? $1000 88 Into how many constellations is the celestial sphere divided by the IAU? $200 New moon. A solar eclipse can only happen during a $400 Total eclipse of the sun If you are in the Moon’s umbral shadow, then you will witness $600 New moon on ecliptic at apogee What conditions are necessary for an annular solar eclipse? $800 New moon on the ecliptic at perigee What conditions are necessary for a total solar eclipse? $1000 Show your visual representation Draw a solar eclipse showing the penumbra and umbra of the moon’s shadow on earth $200 North pole Where on Earth would you be if Polaris was at your zenith? $400 ecliptic What celestial line is a product of the Earth’s orbit around the Sun? $600 23 hours and 56 minutes You note that a particular star is directly overhead. It will be directly overhead again in $800 0 hours to 23 hours What is the range of values for Right Ascension $1000 47 degrees If Seattle is at 47 degrees north latitude on earth where is Polaris in the sky $200 Northstar Of all the visible objects in the sky, which appears to move the least? $400 Shorter distance Is a star with a large parallax and great distance or short distance from earth $600 Precession The fact that Polaris will not always be the North Star is due to what Earth motion? $800 26,000 years How long is the precession cycle $1000 He realized that the sun was directly overhead in one city and at a slight angle in another at the same time and therefore realized the Earth was curved. He realized the distance between the cities was a 7 degree difference or about 1/50th of the earth’s total conference Explain how Eratosthenes measure the circumference of our planet
