The questions below accompany the lab assignment "Earth-Sun Relations", read the lab manual and respond to the questions posed in the manual in the spaces provided below.

The first section of this "lab" is a quick review of the content material associated with the topic.

If you get most of the content questions on the first page correct, you are probably ready to move on to the skills development questions on the subsequent pages.

If you get more than a few of them incorrect, you should review the chapter in the text dedicated to explaining the how the earth's axial tilt and orbit around the sun function to create the seasons.

These the questions on this page are worth only 1 point per question.

Subsequent questions may be worth significantly more points.
