Describe how a person can roughly know his or her latitude on the Earth by the
location of the Big Dipper in the night sky.

Find the Big Dipper, then follow a line through the last 2 stars in the 'bowl' north and this will lead you to the North Star (Polaris)...it's the next brightest star you'll see on that line. You're lattidude is the same as the angular distance from the northern horizon to Polaris. For example, I live at 41 deg. N. lattitude, so Polaris is always 41 deg. above the horizon.

The top of the Big Dipper's bowl is about 20° from the celestial north pole. In the spring when the big dipper is near the meridian ( the highest it gets), one can see how high the dipper is. At the equator the big dipper would be about 20° above the northern horizon, at 20° N latitude it would be 40° above the northern horizon, and at 40° N latitude the big dipper would be 60° above the northern horizon. At 70° N latitude, the big dipper is around your zenith in the spring.

Big dipper cannot be seen from most of the southern hemisphere.
