Which map feature best indicates whether two regions have the same elevation?

a) contour
b) relief
c) slope
d) symbol

A) contour

Explanation:

Contour lines are map features that shows places of equal elevations. Each contour has a value that connotes the elevation and relief pattern in a particular region.

Contours are the basis of topographic map. Topographic maps shows differences in elevation from one place to another using contour lines. All points on a contour line have the same elevation.

It is a general rule that contour lines don't cross one another and they close at a point. Contours lines can be straight, curved and they close up or extend out of a map. Contour lines don't also branch like stream patterns on a map.

The closer contour lines are, the more steep the slope is. When contours are far apart it shows a plain or flatland and a gentle slope.

Contours find a lot of use in geologic works, in the military and other environmental related areas. It is common to often use contours to draw topographic profiles which can easily be used to view the landform.

a

Explanation:

contour

d. new methods of assembly are introduced.

explanation:

this allows for the goods to be made on a larger scale. not faster because now it is shown to be made better, hence the greater productivity in the question. it is calling for something new to be introduced.
