Answer:
In " errors due to the curvature " the points appears to be lower than they are in reality while
In " errors due to Refraction " The points appears to be higher than they are in reality .
Step-by-step explanation:
The difference between both errors
In " errors due to the curvature " the points appears to be lower than they are in reality while
In " errors due to Refraction " The points appears to be higher than they are in reality .
when the effects of both Errors are combined the points will appear lower and this is because the effect of "error due to the curvature" is greater
