What is the contour interval of map 1?

20 feet
In every map, on the right-hand bottom side, the contour interval is described. The commonly utilized contour interval is 20 feet for a 1:24,000 map scale.

What is a contour line * 1 point?

Contour: A Contour line may be defined as an imaginary line passing through the points of equal elevation. Characteristics of Contour line: Closed contour lines with higher values inside show a hill. The variation of the vertical distance between any two contour lines is assumed to be uniform.

What are contour lines Question Answer?

Answer: Contour line, a line on a map representing an imaginary line on the land surface, all points of which are at the same elevation above a datum plane, usually mean sea level. Numbers on the lines give the height in feet. (Sea level is zero.) Lines drawn closely together indicate that a slope is steep.

What are the numbers on contour lines?

The painted lines are topographic contours: lines of equal elevation (height above sea level). So, we have contours at 0′, 500′, 1000′ and so on.

What are the 3 types of contour lines on a map?

There are 3 kinds of contour lines you’ll see on a map: intermediate, index, and supplementary. Index lines are the thickest contour lines and are usually labeled with a number at one point along the line.

What are contour lines Grade 6?

Contour lines show all the places that are the same height above sea level. They also tell us about the slope of the land. On a steep slope, the lines are close together. On a more gentle slope, they are farther apart.

What are contour lines Class 7?

(i) Contour lines are isolines of height. (ii) These are drawn by joining the places of equal altitude. (iii) These help in identification of land forms and their altitude from sea level. (iv) These lines also help us to understand the nature and direction of the slope.

What is a contour line Class 5?

A contour line is an imaginary line on a map connecting points at the same height above sea level.
