  13. Seasons Fig 3.12 Arbogast Geog 096: Weather, Climate and Landscapes

  14. Our seasons are not controlled by distance from Sun Fig 3.4 Arbogast but our climate may be! Geog 096: Weather, Climate and Landscapes

  15. Review Which of the following factors does NOT contribute to the formation of Earth’s seasons? • Rotation of the Earth on its axis • Revolution of the Earth around the Sun • Tilt of the Earth’s axis relative to plane of the ecliptic • Axial parallelism • Migration of the subsolar point Geog 096: Weather, Climate and Landscapes
