Question

contour interval = 50 meters
what is a possible elevation of point a?
a) 575 meters
b) 600 meters
c) 710 meters
d) 655 meters

Explanation:

Step1: Determine the contour interval

The contour interval is given as 50 meters.

Step2: Identify the elevation of the innermost contour around point A

The innermost contour around point A is higher than the 600 - meter contour (since the contour interval is 50 meters, the next contour after 600 would be 650).

Step3: Analyze each option

• Option A: 575 meters is less than the 600 - meter contour level around point A, so it is incorrect.
• Option B: 600 meters is the value of a contour line below the innermost contour of point A, so it is incorrect.
• Option C: 710 meters would be \(600+ 2\times50 = 700\) (if we consider two intervals above 600), but 710 is not a multiple of 50 added to 600 in a simple contour - interval - based calculation.
• Option D: 655 meters is between 650 (the innermost contour value, \(600 + 50\)) and 700 (\(600+2\times50\)).

Answer:

D. 655 meters
