## What does a gentle slope look like?

Gentle: Contour lines showing a uniform, gentle slope will be evenly spaced and wide apart.

Easy walking.

Steep: Contour lines showing a uniform, steep slope on a map will be evenly spaced, but close together..

## What are the 3 types of contour lines?

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. … Intermediate lines are the thinner, more common, lines between the index lines.More items…

## How do you tell if a slope is steep or gentle?

The space between contour lines reflects the slope. When contour lines are closer to each other, then slope is called steep slope. When contour lines are further apart from each other, then slope is gentle slope.

## What is gentle and steep slope?

Slope is a type of surface where one end of the surface is higher than the another end of the surface. … 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 do you know if a slope is steep?

When you look at the two lines, you can see that the blue line is steeper than the red line. It makes sense the value of the slope of the blue line, 4, is greater than the value of the slope of the red line, . The greater the slope, the steeper the line.

## How do you find the slope of a contour map?

To calculate a percent slope, simply divide the elevation change in feet by the distance of the line you drew (after converting it to feet). Multiply the resulting number by 100 to get a percentage value equal to the percent slope of the hill.

## What does a steep slope look like on a topographic map?

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. Broadly spaced contour lines indicate a shallow slope.

## How do you read a hill on a map?

Remember contour numbering reads up hill – in other words the top of the number is uphill and the bottom is downhill. Also remember the closer contour lines are together, the steeper the slope.

## How do I find the slope of the line?

The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .

## What are the 5 Rules of contour lines?

Rule 1 – every point of a contour line has the same elevation. Rule 2 – contour lines separate uphill from downhill. Rule 3 – contour lines do not touch or cross each other except at a cliff. Rule 4 – every 5th contour line is darker in color.

## What is the distance between two contour lines called?

contour intervalThe elevation difference between two adjacent contour lines is called the contour interval (CI). Usually the contour interval is noted on the map legend. In most topographic maps every 5th contour line is drawn in bold print or wider than other contours. Such lines are called index contour lines.
