    • A. 

      (a) Summer

    • B. 

      (b) Winter

  • 18. 
    Which of the following describes one reason that the northern and the southern hemispheres have different seasons at the same time?  
    • A. 

      (a) The Earth is closer to the Sun during summer in the southern hemisphere and is farther from the sun during winter in the northern hemisphere.

    • B. 

      (b) During the time of the year when the Sun is high in the sky in the northern hemisphere it will be low in the sky in the southern hemisphere.

    • C. 

      (c) The Earth is tilted, so the Sun is closer to one hemisphere than the other, which causes one hemisphere to be in winter and the other in summer.

    • D. 

      (d) The energy received at Earth from the Sun changes throughout the year providing more energy to one hemisphere than the other.

    • E. 

      (e) The amount the Earth is tilted changes over the course of the year and causes the amount of sunlight that reaches each hemisphere to be different which causes the seasons to be opposites.
