Question

You started hiking the Appalachian Trail at Springer Mountain in Georgia. You finally reach Maine, the last state on the Appalachian Trail. Wanting to know how mu Ch further you have to hike, you pull out a 1:500, 000 scale map of the state You measure 35.6 inches from the Maine border (where you are standing) to Baxter Peak at the top of Mount Katahdin (the end of the trail). How many miles do you have to go? How many inches are there in a mile? What delineates the boundaries of a quadrangle map? What does a "15-minute quad" map represent? What is an isoline? Give two examples of isoclines used on maps. Explain how the elevation at the top of a hill is determined from a map with contour

Explanation / Answer

2. Here in this question, the Reference Factor is 1:500,000, so 1 inch on the map = 500,000 inches on the ground. To find out how many miles 500,000 inches equals, divide 500,000 inches by 63,360 (63,360 inches = 1 mile). The answer is 7.89 miles (or approximately 7.9 miles). So, one inch on the map = about 7.9 miles on the ground. So 35.6 inches on map will be equal to,

35.6* 7,89= 280.884 miles

3. The boundaries of a quadrangle map is delineated by lines of latitude at the top (north) and bottom (south) and by lines of longitude on the left (west) and right (east).

4. It provides a detailed topographic map coverage of the entire United States at the same scale.

5. Isolines are line joining points of equal value on maps.

6.

a)Isobars: Lines representing points of equal atmospheric pressure.

b)Isohytes: Lines representing points of equal precipitation.
