It is plain, therefore, that the inclination of theearths axis determines the exact boundaries of the zones. Show each zone on a globe and point out its boundaries (). What is the width of each in degrees? Find the ap-proximate width in miles. (Each of these degrees is aboutsixty-nine miles.) What is the direction of the suns rays ineach zone, and the resulting temperature ? Should you expectto find a very different temperature in moving across theboundary line between two neighboring zones ? Why ? Review Questions. — (1) What is the earths axis? (2) Whatwas formerly believed about the earths movement? (3) In whatdirection does the earth rotate ? (4) What changes in the stars resultfrom the earths revolution ? (5) What other effect of revolution isnoticeable? (6) With a pencil, illustrate the movement of theearth around the sun (Figs. 6-9). (7) What
