Tic Tac Toe Review Seasons and Moon Phases Directions: You must complete one row across AND one column down. All of these are good review activities, so it may be helpful to do more than one row or column! 1. Compare and contrast: - seasons of winter and summer for the northern hemisphere AND -Solstice and equinox days 4. What season is it in the Northern Hemisphere according to this image?: 1. Name it 2. Explain the length of day and angle of the Sun’s rays during this season. 3. Explain what season will come next. 7 Draw the orientation of the Sun, Earth and Moon for each of the following phases: 1. Full moon 2. Waxing Gibbous 3. Waning Gibbous 2. Draw a picture and give a written explanation for why we have seasons on Earth. 3. What type of moon is in the picture below: 1. Name it 2. Draw the arrangement of the Sun, Earth and Moon for this phase. 3. Explain what the next phase of the moon will be. 5. Compare and Contrast the full and first quarter moon. 6. Draw and label a diagram showing how Earth orbits the Sun. Label the four positions for the Earth at the beginning of each season. 8. Describe how length of day and the angle of the Sun’s rays vary throughout the year for someone at 33o S latitude. 9. Draw a picture and give a written explanation of synchronous rotation. 1. Compare and contrast seasons of winter and summer in the NH: Summer- NH tilted towards the sun, long days, sun is high in the sky and strikes at a more direct angle Winter- NH tilted away from the sun, shorter days, sun is lower in the sky and strikes at an indirect angle Compare and Contrast Solstice and Equinox days Solstice- when the sun is the farthest north or south of the equator, start the seasons of winter and summer, have the longest days on summer solstice, shortest day on the winter solstice Equinox day- when the sun is directly overhead at the Equator, start the seasons of fall and spring, almost all latitudes on Earth experience 12 hours of daylight 2. Draw a picture and explain why we experience seasons on Earth. The Earth’s axis is tilted 23.5o toward the distant star Polaris. As the Earth orbits the Sun, the hemisphere that is tilted toward the Sun changes. When the hemisphere is tilted toward the sun, that hemisphere experiences summer. The angle of the Sun’s rays in the sky is higher and the days are longer. When a hemisphere is tilted away from the Sun, it experiences winter. The days are shorter and the angle of the Sun in the sky is lower. 3. Waning gibbous moon (see more than half of the disk of the moon illuminated on the left side). The next phase would be a third (last) quarter moon. 4. In the picture the northern hemisphere would be experiencing winter. You know this because the NH is tilted away from the Sun. The daylight hours would be short and the sun would be low in the sky. The angle of the Sun’s rays would be low and indirect. The next season would be spring. 5. During the Full moon, the Earth/Moon/Sun are all in a line. The moon is on the opposite side of the Earth as the Sun. From the Earth you see the entire disc of the moon illuminated. During the First Quarter moon, the Earth/Moon/Sun are at right angles. An observer from Earth would see the right half of the disc of the moon illuminated. 6. 7. See answer 3. 8. Someone at 33oS would experience the opposite seasons that we experience in the Northern Hemisphere. During December-March they would have the sun high in the sky and have long days. During June-September they would have the sun low in the sky and have shorter days. 9. Synchronous rotation describes the fact that the Moon orbits the Earth at the same rate that it revolves. Each motion takes 27.3 days. This means that we only ever see one side of the moon from Earth.
