How do you read contour lines on a map?
How To Read Contour Lines
- 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.
- Supplementary lines appear as dotted lines, indicating flatter terrain.
Is Table Mountain an icon or attraction?
Table Mountain is the most iconic landmark of South Africa. It is also the country’s most photographed attraction and its famous cable car took millions of people to its top. Table Mountain has become the single most welcoming icon to not only our people, but travellers from all over the world.
What are contours answer?
Complete answer: Contour lines are lines drawn on a topographic map connecting points of equal elevation. They are also called “level- lines”. Contour lines are useful because they depict the shape of land used by countless professions- foresters, hunters,miners,engineers etc.
How do you get contour lines?

- Gather supplies.
- Draw orientation lines on the drawing paper.
- Make a clay mountain and cut layers out of the mountains.
- Use the clay layers to draw contour lines.
- Complete your contour maps with DOGSTAILS.
- Share your contour map and explore contour maps of your local area.
What is the shape of contour line?
At a stream junction, contour lines form an “M” or “W” shape. This can be interpreted as two “V-shaped contours intersecting.
How would you describe Table Mountain?
Table Mountain, Afrikaans Tafelberg, flat-topped mountain in southwestern South Africa, overlooking Cape Town and Table Bay and dominating the northern end of the high, rocky Cape Peninsula. Its tabular shape results from nearly horizontal layers of sandstone exposed by vigorous wind and water erosion.

What are contour lines Grade 6?
Contour lines show all the places that are the same height above sea level. They also tell us about the slope of the land. On a steep slope, the lines are close together. On a more gentle slope, they are farther apart.
How are contours drawn?
contour drawing, version of outline drawing, in which the artist, looking closely at the contour of an object, transfers it in one continuous line to paper without looking down to see what he is doing, except when he needs to place an internal feature such as an eye.
What Colour are contour lines on a map?
brown
Topographic contours are shown in brown by lines of different widths. Each contour is a line of equal elevation; therefore, contours never cross.
What are the features of contours?
Characteristics of Contours
- Must close on themselves, on or off the map.
- Perpendicular to the direction of max.
- Slope between them is assumed uniform.
- The distance between them indicates the steepness of the slope, gentle or steep.
- Irregular signify rough, smooth signify gradual slopes.
How does Table Mountain look like?
How are tabletop mountains formed?
Around 300 million years ago the mountain was still at sea level during an ice age and ice sheets flattened the layers of sandstone creating the flat surface that today we call the ‘Table Top’. When the continents split apart, stresses and pressures built up in the earth’s crust.
What do the lines on a topographic map indicate?
Note: The intervals are increasing, therefore, the contours indicate a hill. The peak is normally considered to be located at half the interval distance. Widely separated contour lines indicate a gentle slope. Contour lines that are very close together indicate a steep slope.
What is a contour line on a map?
Put simply, contour lines mark points of equal elevation on a map. If you trace the length of a line with your finger, each point you touch is the same height above sea level. If you were to walk the path of a contour line in real life, you would remain at the same elevation the whole hike, never traveling up or down.
How to draw a profile from a contour map?
From the contour map, a profile can be drawn of the terrain. Example 2 – Draw a profile showing the elevations of the contours. Note: The intervals are increasing, therefore, the contours indicate a hill. The peak is normally considered to be located at half the interval distance. Widely separated contour lines indicate a gentle slope.
How do you read elevation on a contour line?
If you’re looking at an index line, it’s easy to read the elevation because it is clearly labeled. However, interval lines are somewhat trickier. To determine their elevation, you’ll need to know the contour intervals. Contour intervals tell you the change in elevation between any two contour lines.
