you subtract both elevation and then that would be the elevation...
when you want to find out the differences between the points
yes, it is believed that the Romans used this method when extreme accuracy was necessary
The elevation of a point that falls between two contour lines can be approximately determined by averaging the elevation of those two points. Assuming the point is somewhat halfway between the lines, this can be done by adding the elevations and dividing by two.
The distance between two points must be known to determine the average slope between the two points. You must also know the change in elevation.
property line
because they are not high points of elevations and divides are high points of elevation
hi my name is bhavya
you simpily project all your points up
an imaginary line, joining the equal elevations of the points
Landforms are commonly classified according to differences in relief - the difference in elevation between highest & lowest points
potential difference between two points in a circuit
Distillation is based on the differences between boiling points of the components of a liquid.
