The blue ridge would be the answer to your question
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.
In most cases, as altitude increases, the air in the troposphere cools. Vertical mixing occurs as a result of warm air rising. However, a layer of cool air may form beneath a layer of warm air on occasion. Temperature/thermal inversion refers to this deviation from normal temperature.
When an inversion occurs, polluted areas (such as London and Donora PA) experience unhealthy air and an increase in smog because pollutants are trapped at ground level rather than circulating away.
