   “Orbit diagram, top view from above the North Pole, not to scale:” Noah looks at Earth at place P on the orbit diagram. The North Pole leans toward the Sun. Which season is it in the Northern Hemisphere?

   • Summer, because the north leans toward the Sun

   • Summer, because Earth is closest to the Sun here
   • Summer in both hemispheres at once

   Use this

   Orbit diagram, top view from above the North Pole, not to scale: the Sun in the center; Earth at four places lettered P (left), Q (bottom), R (right) and S (top), counterclockwise; at every place the axis is drawn the same way, with the North Pole leaning toward the right of the page. Place R is circled.

7. 6.

   Pia finds Earth at place R, where the North Pole leans away from the Sun. Which season is it in the Northern Hemisphere?

   • Winter in both hemispheres at once
   • Winter, because the north leans away from the Sun
   • Winter, because Earth is farthest from the Sun here
   • Summer, because the axis has turned toward the Sun
8. 7.

   “Orbit diagram, top view from above the North Pole, not to scale:” Earth is at place P, with the North Pole leaning toward the Sun. Ren asks about the other half of Earth. Which season does the Southern Hemisphere have?

   • Spring, because the axis is turning around
   • Winter, because the south leans away from the Sun
   • Summer, because Earth is closest to the Sun here
   • Summer, the same as the north at that time
9. 8.

   In December, Tala builds a snow fort in Minnesota that is mostly snow and a little bit of hope. What season is it in Australia?
