Atopographic map would be most useful for which activity? a. finding the average precipitation in your city b. finding the lowest point in your city c. determining the highest temperature in your state d. finding a source of copper or iron in your state

A topographic map would be most useful in finding the lowest point in your city. A topographic map is a map that shows the relief of a certain area which means that it shows the elevations of certain areas through certain lines on the map. Because of this it is possible to see elevation changes on the map and ultimately determine high and low points in an area such as in your city. These other examples would most likely require a different kind of map. 

Assuming this is a question on a test just name a restaurant by your house and the state you live in, its not too difficult : )
