What is the difference between gentle slope and steep slope?

Slope is a type of surface where one end of the surface is higher than the another end of the surface. The space between the contour lines reflects the slope. 1) Where the contour line is farther apart, it is called gentle slope. 2) Where contour lines are closer to each other, it is called a steep slope.

How does the spacing of the contour lines show the difference between gentle and steep slopes?

1. Contour lines do not cross each other, divide or split. 2. Closely spaced contour lines represent steep slopes, conversely, contour lines that are spaced far apart represent gentle slopes.

How will you identify gentle and steep slopes?

When contour lines are closer to each other, the slope is steep. When contour lines are further apart from each other, the slope is gentle.

Is a hill concave or convex?

concave When the contour lines of a hill are far apart at first, then come close together. The hill will be easy to climb at first, but then it gets steep. convex When the contour lines of a hill are close together at first, then get farther apart. The hill will be hard to climb at first, but then it becomes easy.

Why do contour lines never cross?

Contour lines never cross on a topographic map because each line represents the same elevation level of the land.

What is the other name of contour lines?

A contour line (also isoline, isopleth, or isarithm) of a function of two variables is a curve along which the function has a constant value, so that the curve joins points of equal value.

What is meant by a 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.

What is the shape of contour lines?

At a stream junction, contour lines form a “M” or “W” shape. This can be interpreted as two “V-shaped contours intersecting.

What are the characteristics of contour lines?

The contours have the following characteristics:

  • Contour lines must close, not necessarily in the limits of the plan.
  • Widely spaced contour indicates flat surface.
  • Closely spaced contour indicates steep ground.
  • Equally spaced contour indicates uniform slope.
  • Irregular contours indicate uneven surface.

What is purpose of contouring?

What is the purpose of contour? The whole point of contouring is to enhance or change the shape of your face with makeup, but its effects don’t have to be all that drastic. “From 2012 to 2018, contouring based on your face shape was seemingly very important,” says LA-based makeup artist Jenna Nicole.

What are the uses of contouring?

Uses of the Contour Lines

  • To estimate the water storage capacity, back water limit and max .
  • Volume of the proposed excavation wok,
  • To decide whether certain location is visible from another location,
  • To decide exact line of railway or road way haing safe slope,
  • To determine the ground water level from contours of ground water.

What are the methods of contouring?

There are two methods of contour surveying: Direct method. Indirect method….Indirect Method of Contouring

  • Method of squares.
  • Method of cross-section.
  • Radial line method.

What is block contouring?

By squares (block contouring)- In this method the area to be surveyed is dividing into no of the square of size 5 to 20m. depending upon the nature of ground and contour interval required. The elevation of the corner of the square is determined by the mean of the process of levelling.

What is direct contouring?

Methods of Contouring Direct Method • In the direct method of contouring, the reduced level of various selected points on a contour line are obtained and their positions are located. The contours are then drawn by joining these points. It is a very accurate method but it is slow and tedious.
