# What Two Things Does A Topographic Map Show?

What does a topographic map show? it shows natural features such as rivers and lakes. They also show some features made by people such as brodges. They also show elevation.

## How do you determine elevation on a topographic map?

You can figure out the elevation of any point by finding the nearest labeled line, counting the number of lines above or below it, multiplying by the contour interval, and adding or subtracting the result from the nearest marked contour line. The more closely spaced the contour lines, the steeper the slope.

## What do contour lines indicate on a topographic map quizlet?

A contour line on a topographic map connects points of equal elevation. The change in elevation from contour line to contour line is called the contour interval. such as 1,600 or 2,000 feet.

### What are topographic symbols?

Symbols are used in topographic maps to identify cultural and natural features. Symbols come in different shapes, sizes and colors to uniquely identify such features on the map.

### How do you explain topography?

Topography describes the physical features of an area of land. These features typically include natural formations such as mountains, rivers, lakes, and valleys. Manmade features such as roads, dams, and cities may also be included. Topography often records the various elevations of an area using a topographical map.

### What will a hill look like on a topographic map?

Concentric circles indicate a hill. When contour lines form closed loops all together in the same area, this is a hill. The smallest loops are the higher elevations and the larger loops are downhill.

### What is the actual distance represented by 1 inch on this map?

On the map 1 inch is equal to 0.4 miles.

### What does a Depression look like on a topographic map?

A depression is represented by a series of concentric closed contours with the inner contours having lower elevation than their outer surrounding. There are small tick marks or hachures on these contour lines pointing towards lower elevation.

### What are the 5 colors on a map?

• RED -Overprinted on primary and secondary roads to highlight them. …
• BLACK -Manmade or cultural features.
• BLUE -Water-related features.
• BROWN -Contour lines and elevation numbers.
• GREEN -Vegetation features.
• WHITE -Sparse or no vegetation. …
• PURPLE -Denotes revisions that have been made to a map using aerial photos.

### What is the purpose of topography?

Objectives. An objective of topography is to determine the position of any feature or more generally any point in terms of both a horizontal coordinate system such as latitude, longitude, and altitude. Identifying (naming) features, and recognizing typical landform patterns are also part of the field.

### What are the three main types of topography?

Topography Types

• Karst Topography. Karst topography describes the distinct landscape that is made when underlying rocks dissolve or change shape. …
• Mountain Topography. Topographical maps show landforms such as hills and mountains. …
• Vegetation, Elevation and Glaciers.

### How do you explain topography of an area?

Slope and topography describe the shape and relief of the land. Topography is a measurement of elevation, and slope is the percent change in that elevation over a certain distance. Topography may be measured with lines that connect points representing the same elevation; these are called topographic contours.

### What are 10 symbols on a topographic map?

Topographic Map Legend and Symbols

• Brown lines – contours (note that intervals vary)
• Black lines – roads, railroads, trails, and boundaries.
• Red lines – survey lines (township, range, and section lines)
• Blue areas – streams and solid is for larger bodies of water.
• Green areas – vegetation, typically trees or dense foliage.

### What are the five map symbols?

Most maps will have the five following things: a Title, a Legend, a Grid, a Compass Rose to indicate direction, and a Scale.

### What are the three types of map symbols?

Map symbols are categorized into three categories: Point Symbol, Line Symbol and Area Symbol.

### What are four main uses of topographic maps?

Topographic maps have many multiple uses in the present day: any type of geographic planning or large-scale architecture; earth sciences and many other geographic disciplines; mining and other earth-based endeavours; civil engineering and recreational uses such as hiking and orienteering.

### What is topographic effect?

The topographic effect is the variation in radiance from an inclined surface compared to the radiance from a horizontal surface as a function of the surface orientation relative to the light source and sensor position.

### How does a topographic map work?

A map with contour lines on it is called a topographic map. Topographic maps use a combination of colors, shading and contour lines to represent changes in elevation and terrain shape. Essentially, topographic maps represent the three-dimensional landscape of Earth within the two-dimensional space of a map.

### What is the meaning of Topograpiya?

### What does blue mean on a topographic map?

The colors of the lines usually indicate similar classes of information: topographic contours (brown); lakes, streams, irrigation ditches, and other hydrographic features (blue); land grids and important roads (red); and other roads and trails, railroads, boundaries, and other cultural features (black).

### What do colors mean on a map?

Physical maps use color most dramatically to show changes in elevation. A palette of greens often displays elevations. Dark green usually represents low-lying land, with lighter shades of green used for higher elevations. … Green-gray, red, blue-gray, or some other color is used for elevations below sea level.
