Line joining points of equal elevation on earth's surface is called

Answer 1

Line joining points of equal elevation on the earth's surface is called contour lines.

An imaginary line joining the points of equal elevation on the surface of the Earth represents the contour line.

A line laying on the ground which maintains a constant inclination to the horizontal is known as contour gradient. It is found out by instrument clinometer. The method of representing the height on the map by using contour lines is called Contouring.

Let us study some of the features of contour lines:

• The variation of the vertical distance between any two contour lines is assumed to be uniform.
• The horizontal distance between any two contour lines indicates the amount of slope and varies inversely on the amount of slope.
• The steepest slope of terrain at any point on a contour is represented along the normal of the contour at that point. They are perpendicular to ridge and valley lines where they cross such lines.
• These lines do not pass through permanent structures such as buildings.

Answer 2

Answer:

Line joining points of equal elevation on earth's surface is called Contour lines.

Explanation:

A contour line is an imaginary line that connects locations that have the same height above sea level, and contouring is the way of expressing height on a map using contours.

Isolines, also known as contour lines, can be used to represent elevation on a map by, for example, connecting points of equal elevation. When contour lines are close together, they reflect a severe slope; when they are far away, they show a gradual slope.

A contour is a line on a map that connects points of equal elevation.

A contour line (also known as a "contour line") in cartography connects locations of similar elevation (height) above a specific level, such as mean sea level. A contour map's contour interval is the elevation difference between successive contour lines.

Therefore, Line joining points of equal elevation on earth's surface is called Contour lines.
