# Quick Answer: Lesson Plan How To Read A Topographical Map For Elementary?

## How do you teach topographic maps?

Draw several lines, called transects, across a USGS topographic map. Create cross-sections (profiles) along these transects, using the contour lines to determine the elevation at each position along the transect.

## How do you read a topographical map?

Every point of the same contour line has the same elevation. One side of a contour line is uphill and one is downhill. Contour lines close to form a circle (or run off the side of the map). The area inside the circle is almost always higher than the contour line.

## What are the six rules for reading a topographic map?

Topographic Map Rules

• Contour Lines Never Cross.
• Measuring Steepness.
• Stream Flow Direction.
• Contours Close.
• Concentric Circles.
• Elevation Between Lines.

## What are the symbols on a topographic map?

Topographic Map Legend and Symbols

• Brown lines – contours (note that intervals vary)
• 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 is a topographic map kid definition?

A topographical map is one that shows the physical features of the land. Besides just showing landforms such as mountains and rivers, the map also shows the elevation changes of the land. Elevation is shown using contour lines. Every point on the map touching the line should be the same elevation.

## What are the parts of a topographic map?

Topographic maps are a detailed record of a land area, giving geographic positions and elevations for both natural and man-made features. They show the shape of the land the mountains, valleys, and plains by means of brown contour lines (lines of equal elevation above sea level).

## What does a closed circle mean on a topographic map?

All points on a contour line have the same elevation — that is, they’re all at the same height above sea level. A series of concentric contour lines that are closed onto themselves indicate mountains or hills. Closed contour lines look like misshapen circles or loops. The smallest circle shows the peak.

## 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.

## Why is it called a 7.5 minute map?

For example, a 7.5-minute map shows an area that spans 7.5 minutes of latitude and 7.5 minutes of longitude, and it is usually named after the most prominent feature in the quadrangle. Others show a whole area—a county, State, national park, or place of special interest.

## What do numbers on a topographic map mean?

Horizontal distance is found on the scale. As you look at the map, notice that the contour lines enclose smaller and smaller areas. The smallest circles represent the tops of peaks, and some are marked with x’s with numbers next to them. The numbers are the elevation at the top of the peak.

## What is Rule #4 when reading a topographic map?

Rule 4 – every 5th contour line is darker in color. This is an INDEX contour line. Rule 5 – Contour lines are closer together in steep terrain and farther apart in flat areas.

## How do you count topographic lines?

Maps generally count five contour lines from one index line to the next, including the next index line.

1. As with counting from one number to the next,
2. like from five to 10,
