A topography map provides visual information about elevations, either by color or by circles, so the answers would be:
- areas with mountains
- regions with a high elevation.
The change of elevation (going high or low) would be represented by circles. The closest the circles are to each other, the steeper is the variation.
A topographic map is usually a large-scale map (showing a small area, like your neighbourhood, not a whole country for example). If there are state boundaries or any kind of road passing in that frame, yes they will be shown on the map... but it's not the primarily use of a topographic map.
