**Relatively close contours** Indicates a fairly steep slope. Contours that are further apart represent relatively flat slopes. The area outlined in orange in the image above shows an area with a fairly steep slope, while the area outlined in purple is a relatively flat area.

## How do you determine an uphill road on a topographic map?

**Read the topographic map**

- Contour lines show the height of the ground.
- Contour interval shows the vertical distance between each contour line. …
- A sharply tapering contour line indicates the upslope direction.
- Circular contour lines usually indicate downslope directions.

## What are the symbols on the topographic map?

**Topographic Map Legends and Symbols**

- Brown lines – contour lines (note the different intervals)
- Black lines – roads, railroads, trails and boundaries.
- Red Lines – Survey Lines (Country, Extent, and Section Lines)
- Blue area – Streams and solids are used for larger bodies of water.
- Green Space – Vegetation, usually trees or dense foliage.

## What are the 4 types of slopes?

There are four different types of slopes.they are **positive, negative, zero and indeterminate**.

## How do gentle and steep slopes appear on the map?

**Relatively close contours** Indicates a fairly steep slope. Contours that are further apart represent relatively flat slopes. The area outlined in orange in the image above shows an area with a fairly steep slope, while the area outlined in purple is a relatively flat area.

## How would you identify gentle and steep slopes?

**when contours are close to each other**, the slope is steep. When the contours are far apart, the slope is gentle.

## Which slope is the gentlest?

If you use a topographic map, the gentlest slope will be **where the lines are farthest apart**.

## What are steep and gentle slopes?

Steep slope refers to a steep slope; gentle slope refers to **slightly inclined**. The steep forest slope in Figure 1.1 contrasts with the gentle slope of the river path as it flows between them. … a 6% slope means that the road elevation changes by 6 feet for every 100 feet of horizontal distance (Figure 1.3).

## What is a gentle slope?

gentle slope or curve **not steep or severe**.

## What are the types of slopes?

**In the previous section, you have discovered that there are four types of slopes.**

- Positive slope (when the line goes uphill from left to right)
- Negative slope (when the line goes downhill from left to right)
- Zero slope (when the line is horizontal)
- Undefined slope (when the line is vertical)

## How do you interpret the terrain?

terrain **Describe the physical characteristics of a piece of land**. These features often include natural formations such as mountains, rivers, lakes and valleys. Man-made features such as roads, dams, and cities may also be included. Terrain usually uses a topographic map to record various elevations of an area.

## What does a concave bevel look like?

**Topographic features that are rounded inward, such as the interior of a bowl**, i.e. from steeper to steeper. Slope Shape: Avalanches occur on any steep slope without thick anchors, regardless of the shape of the slope. …

## What is the standard form slope?

Standard form is another way of writing the slope-intercept form (as opposed to y=mx+b).it is written as **Ax+By=C**. You can also change the slope-intercept form to the standard form as follows: Y=-3/2x+3. … A, B, C are integers (positive or negative) with no standard form of fractions or decimals. The word « axe » is positive.

## What is not a slope type?

undefined slope or **infinite slope**Indicates that the line moves neither left nor right, as is the case with vertical lines.

## What does a negative slope look like?

Graphically, a negative slope means that **As the line on the line chart moves from left to right, the line goes down**. We will learn that there is a negative correlation between « price » and « quantity demanded »; that is, when prices are higher, consumers buy less. …Graphically, the line is flat; the rise beyond the run is zero.

## What do topographic maps show us?

A topographic map is a detailed record of an area of land, giving the geographic location and elevation of natural and man-made features.they show **Outline land shapes of mountains, valleys and plains with brown contour lines** (elevation contour).

## What is the purpose of topography?

Terrain aims to be **Determine the position of any feature, or more generally any point, in terms of a horizontal coordinate system, such as** Such as latitude, longitude and altitude. Identifying (naming) features and identifying typical terrain patterns are also part of the field.

## What are the three main types of terrain?

**Terrain type**

- Karst topography. Karst landforms describe unique landscapes formed when underlying rocks dissolve or change shape. …
- Mountain terrain. Topographic maps show landforms such as hills and mountains. …
- Vegetation, elevation and glaciers.

## What is the zero slope equation?

A zero-slope line is a straight, perfectly flat line extending along the horizontal axis of the Cartesian plane. The equation for a zero-slope line is one where the X value may vary but the Y value remains the same.The equation for the zero slope line will be **y = b**where the slope of the line is 0 (m = 0).

## What is a straight slope?

The slope of a line indicates how steeply it slopes.it is also called **gradient**.

## What is C in slope-intercept form?

One form of the equation of the line is called the slope-intercept form because it contains information about these two properties. … the value of c is called **vertical intercept of a line**. It is the value of y when x = 0. When drawing a line, c gives where the line intersects the vertical axis.

## What is a steep slope on a topographic map?

You can calculate the elevation of any point by finding the nearest marker line, counting the number of lines above or below it, multiplying the contour interval, and adding or subtracting the result from the nearest marker contour. **The closer the contour lines are**the steeper the slope.

## Which are gently sloping land?

**flat area** By no means strictly horizontal; there are gentle slopes in seemingly flat areas, but are often imperceptible to the naked eye. To identify these so-called « flat slopes », an accurate survey of the land is necessary.
