12. The geographic grid apportions the globe into hemispheres of 180 lines of longitude. Based on your knowledge of basic geometry, what portion of a sphere does 180 degrees equal? __________________ The grid also defines so-called "central meridians" centered on every 15 degrees of longitude. How many central meridians would there be for a complete sphere? ________________________ Compare this answer to the number of hours in a day. How does it compare?
