Areas of equal elevation are connected by lines on a topographic map.

meridian

longitude

contour

latitude

Contour

Explanation:

These are just lines that follow the points on the map that contain the same elevation, and are not the lines that one sees drawn for finding particular locations on a projected flat surface of the Earth like meridians or parallels, that give us longitude and latitude of a place.

The topographic lines are actually trying to represent (give an image of) the third dimension (elevation) in a two dimensional chart.

f=gm1m2/d^2 it d

f is force g is gravitaiton constant, m1 is mass of first object, m2 is mass of second object. d is distance between two object

true is the correct answer
