What are contour lines for Class 7?

What are contour lines for 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 do you mean by contour interval?

A contour interval is the vertical distance or difference in elevation between contour lines. Index contours are bold or thicker lines that appear at every fifth contour line. If the numbers associated with specific contour lines are increasing, the elevation of the terrain is also increasing.

How does a contour line look in a steep elevation?

Closely-spaced contour lines indicate a steep slope, because the elevation changes quickly in a small area. Contour lines that seem to touch indicate a very steep rise, like a cliff or canyon wall.

What is the difference between a contour line and an outline?

Lines that describe a shape of a figure or an object and also include interior detail. These lines can vary in thickness. an outline is the line made by the edges of an object. Contour lines describe the shape of an object, and include interior detail.

Is a contour line an outline?

Outline: the edge of a shape or figure depicted by an actual line drawn or painted on the surface. Contour line: the perceived line that marks the border of an object in space.

Which best describes a contour line drawing?

Contour drawing is the place where most beginners start, following the visible edges of a shape. The contour describes the outermost edges of a form, as well as dramatic changes of plane within the form. Put simply, a contour line drawing is an “outline drawing,” that uses no shading.
