Answer:
-subtraction
Explanation:
Elevation is the altitude of a place above a reference frame. 
To find the difference between the elevation between two or places on a map, we perform a subtraction operation. 
The differences in elevation is the subtraction of the two elevation values from one another. 
For example if point A on a map is at 60m above sea level and point B is at 100m, the change in elevation is; 
 Change in elevation  = Elevation of B - Elevation of A = 100m  - 60m  = 40m
 
        
             
        
        
        
I think the answer is plate movement. Tectonic plate movement is the movement on the lithosphere. This movement is defined into three; we have the convergent, divergent and transform. Plate movements often caused volcanic eruptions as well as earthquakes, depending on the movement on the plates.
