The answer depends on what relationship - if any - exists between the points in the table. There need not be any relationship.
A line is made up of many points.
It depends on how far away the observer is from the two points.
The approximate gradient of the hill between points x and y can be calculated by taking the difference in elevation between the two points and dividing it by the horizontal distance between them. This is often expressed as the rise over run. If the elevation at point x is higher than at point y, the gradient will be negative, indicating a downhill slope, while a positive gradient indicates an uphill slope. The steeper the hill, the larger the absolute value of the gradient.
The horizontal distance. Points of latitude and longitude can't account for elevation.
you subtract both elevation and then that would be the elevation...
relief
its a closed loop with dashes inside indicates a depression
Contour line connect points of equal elevation on a map, whereas relief is the difference in elevation from the highest and lowest on a map.
The answer depends on what relationship - if any - exists between the points in the table. There need not be any relationship.
A depression contour is a line drawn on a map connecting points of equal depth below a reference point, such as sea level. It represents a depression or a lower elevation relative to the surrounding terrain. These contours help in visualizing the shape and depth of the land surface.
latitude and longitude
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.
Freezing point depression and boiling point elevation are both colligative properties that occur when solute particles are added to a solvent. Freezing point depression lowers the temperature at which a solution freezes, while boiling point elevation raises the temperature at which a solution boils. These changes in the freezing and boiling points affect the physical properties of the solution, making it different from the pure solvent.
the measure of change in elevation in a certain distance is called gradient
altitude differential
Contour lines connect points with the same elevation or value, showing the shape and elevation of the land on a map.
