Question

change your location to houston, texas. identify (by advancing time forward) the circumpolar region in the northern sky – the region surrounding polaris where stars never set. then change your location to winnipeg, manitoba and do the same thing. how do the sizes of these two circumpolar regions compare? options: winnipeg’s circumpolar region is larger than that of houston. houston’s circumpolar region is larger than that of winnipeg. it is impossible to compare because neither city has any circumpolar stars. the two circumpolar regions are equal in size. it is impossible to compare because one city doesn’t have any circumpolar stars.

Explanation:

The circumpolar region (stars never set) around the North Pole depends on latitude. Winnipeg (Manitoba, Canada) is at a higher latitude than Houston (Texas, USA). The higher the latitude, the larger the circumpolar region (since the angle from the pole is related to latitude; the circumpolar region's radius in the sky is equal to the observer's latitude). So Winnipeg, being farther north (higher latitude), has a larger circumpolar region than Houston.

Answer:

Winnipeg’s circumpolar region is larger than that of Houston.
