## What is the opposite of a steep slope?

Selected answer: gentle slope..

## 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.

## Whats the relationship between the steepness of a slope and contour line spacing?

In hilly areas, the contour lines are close together while they are wider apart on flat slopes. The closer the contour lines, the steeper the slope. The wider the contour lines, the flatter the slopes. On a hill, the contour lines form circles; whereby the values of their elevation increase from the edge to the centre.

## What is a steep slope in geography?

Steep slopes are legally defined as hillsides having a 15 foot, or greater, vertical rise over 100 feet of horizontal run, or 15% slope (Figure 1). They are often undesirable ar- eas for development due to the difficulty of building on steep grades.

## What are 4 types of slopes?

Slopes come in 4 different types: negative, positive, zero, and undefined. as x increases.

## 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 a steep slope called?

An escarpment is a steep slope or long cliff that forms as a result of faulting or erosion and separates two relatively level areas having different elevations. Usually scarp and scarp face are used interchangeably with escarpment.

## What is average slope in geography?

The average slope of a terrain feature can conveniently be calculated from contour lines on a topo map. To find the slope of a feature, the horizontal distance (run) as well as the vertical distance (rise) between two points on a line parallel to the feature need to be determined.

## Why do contour lines never cross?

Contour lines can never cross one another. Each line represents a separate elevation, and you can’t have two different elevations at the same point.

## What information does the slope tell you?

The slope of a line is the change in y, y (read “delta y”), divided by the change in x, x (read “delta x”). That is, slope is , which is a rate of change. Stating the units for y and x will help clarify what the slope tells you about how the y-value changes from one x-value to the next.

## Is a 5% grade steep?

Grades are often measured by how high up you go as you progress horizontally. For example, a wheelchair-navigable trail is no more than a five-foot rise in one hundred feet horizontally. This is called a 5 percent grade (i.e., five divided by 100). … Just a bit steeper than a wheelchair-navigable trail.

## What is a 10% slope?

It expresses the ratio of difference in altitude between two points on a slope to the horizontal distance between the points, multiplied by 100. For example a 10 percent slope means that, for every 100 feet of horizontal distance, the altitude changes by 10 feet: {10 ft over 100 ft} × 100 = 10%

## What is the space between contour lines called?

Contour lines–usually curved, parallel brown lines–show the shape and elevation of the land by connecting points of equal elevation. … The space between the contour lines is called the contour interval and represents a specific (set) distance.

## 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.

## What is meant 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.

## What does a positive slope look like?

A positive slope means that two variables are positively related—that is, when x increases, so does y, and when x decreases, y also decreases. Graphically, a positive slope means that as a line on the line graph moves from left to right, the line rises.

## Do steep contour lines indicate water?

Contour lines that are further apart indicates a slope that is relatively flat. The area of the map above boxed in orange shows an area that has a fairly steep slope, while the area boxed in purple is a relatively flat area. Contour lines on the map also show how water will travel across the land.

## What is considered a gentle slope?

The slope distance is 100.2 ft. for a run of 100 ft. As you can see from this example, in a forest, a six percent slope would be considered a gentle slope. … For example, a 25 percent slope is simply a ratio of 25:100.

## How topographic maps show steep and gentle 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.

## What does slope look like?

The slope equals the rise divided by the run: . You can determine the slope of a line from its graph by looking at the rise and run. One characteristic of a line is that its slope is constant all the way along it.
