Name ___________________________________________ Date _____________ Period__________ Study the diagram below and answer the following questions: 1 Points 2 and 3 on the diagram above are showing revolution and rotation of the Earth. How do the rotation and revolution differ? (motion, length, and what do they bring) 2 What does point 7 represents, how large is it and what is the results of it on the seasons? 3 Label positions 8, 6, 5, and 4 with the correct season. 4 Describe the position of the Earth’s tilt and the sun for each of the seasons. Use the Northern Hemisphere as your point of reference. Positon 8: Position 6: Position 5: Position 4: Name _____KEY______________________________________ Date _____________ Period__________ Study the diagram below and answer the following questions: 5 Points 2 and 3 on the diagram above are showing revolution and rotation of the Earth. How do the rotation and revolution differ? (motion, length, and what do they bring) Point 2 shows the revolution of the Earth around the sun. It takes 365 days for the Earth to complete one revolution around the sun. As a result it brings seasons to us. Point 3 shows the rotation of the earth on its axis. It take 24 hours for the Earth to complete one revolution and as a result it brings night and day. 6 What does point 7 represents, how large is it and what is the results of it on the seasons? Point 7 represents the Earth’s tilt. Earth is tilted 23.50 on its axis. The north end of the axis always points toward the North Star. Tilt Axis results in variations of the angle of light striking Earth. 7 Label positions 8, 6, 5, and 4 with the correct season. 8 Describe the position of the Earth’s tilt and the sun for each of the seasons. Use the Northern Hemisphere as your point of reference. Position 8: Autumn or Autumnal Equinox - Approximately September 23 in the Northern Hemisphere Sun passes directly over the equator The Earth's axis is neither tilted toward nor away from the Sun The day is the same length (12 hours ) everywhere The beginning of fall Position 6: When the Earth is tilted away from the Sun, it receives indirect energy – energy that is spread out over a larger area. This causes cooler temperatures. (Winter) Position 5: Spring or Vernal Equinox (equal day and night ) Approximately March 20 in the Northern Hemisphere Sun passes directly over the equator The Earth's axis is neither tilted toward nor away from the Sun The day is the same length (12 hours ) everywhere The beginning of spring Position 4: When the Earth is tilted toward the Sun, it receives direct energy – energy that is concentrated over a smaller area. This causes hotter temperatures. (Summer)
