A map with contour lines on it is called a topographic map. Contour Representation of Landforms.

Contour patterns can be used to recognise distinctive landforms such as ridges valleys and hills Contours may appear as black or coloured lines on maps and are often supported by colour shading to give an impression of relief Cross-sections provide a useful way of visualizing the shape of the land surface but care needs to be.

. You can see from the picture above the link between the shape of a hill and the. Roughly concentric circles are. A B 2 3 E F STATION BS IS FS RISE FALL REDUCEDREMARKS LEVEL 25 Bench mark 1 211 2 114 3 095 4 084 5 155 Last reading 6 188.

The following are some common landforms or relief features that can be represented on map by using contour lines. Major landforms as shown by contours and other graphical features. They join together places of the same height and form patterns that help us to imagine what the land actually looks like.

Con-tour lines never cross one another. Geography SS 2 Week 2. GRA Time left 12453 948008 D E F B- From the site surveying the controls points from 1 to 6 recorded in the tables as BS IS and FS.

Shown on the map as a black dot with the height written next to it. Contour lines are drawn in intervals. These are lines drawn on maps that join places of the same height.

All points on a contour line are at the same elevation. Where contour lines are wide apart the elevation is changing slowly indicating a gentle slope. Using the basic principles of slope shape and altitude it is possible to identify a wide range of physical landforms on maps.

U-shaped contours indicate broader ridges while V-shaped contours represent narrower and sharper ridge lines. Topographic maps use a combination of colors shading and contour lines to represent changes in elevation and terrain shape. Example 1 - In the graphic below what is the vertical distance between the contour lines.

How contour lines show a pair of small hills. The Geography Department would like to thank Year 7 for making such a huge effort. Contour lines are a maps way of showing you how high the land is.

Every point along the line has the same value. Settlement and Transport pattern. LANDFORMS The way in which contour lines are arranged allows us to identify certain landforms and features in the terrain.

Streamsalways flow downhill Contours can and do cross streams. Count them as regular contour lines. Valleys are represented by V- shaped contour lines with the apex of the V- shape pointing towards the highland.

They are usually an orange or brown colour. Low land between hills or mountains. Are lowland between two highlands.

For 125 000 scale maps the interval between contours is usually 5 metres although in mountainous regions it may be 10 metres. Gives the exact height above sea level of a particular location or feature. A rounded contour indicates a flatter or wider drainage or spur.

Sharp contour points indicate pointed ridges. Contour lines connect points that share the same elevation. Street patterns Land use zones OTHER PRIMARY Mining Fishing SECONDARY Heavy or light.

The spacing of the contours lines on the map shows the steepness of slopes. 3 Identify the landforms regarding structural landscapes. Contour lines form a U or V shape that points away from the high land.

Ridges are represented by U or V shaped contour lines with their closed end pointing towards lower elevation. Lines form a V pattern along valleys. Some contour lines have their height above or.

Landforms Understanding how landforms are depicted on topographic maps Landform refers to the shape of the land and is a function of elevation and relief that is the representation as depicted by the mapmaker of the shapes of hills valleys streams or. A contour is a line drawn on a map that joins points of equal height above sea level. Part 2 - Map interpretation Contour patterns can be used to recognise distinctive landforms such as ridges valleys and hills Contours may appear as black or coloured lines on maps and are often supported by colour shading to give an impression of relief Cross-sections provide a useful way of visualizing Topographic maps illustrate the shape of the Earths surface and help.

Land use ie. Mesas buttes conical hills. Drainage and water features the main river and its important tributaries.

Contour lines tend to enclose the smallest areas on ridge tops which are often narrow or very limited in spatial extent. Contour lines join places with the same height above sea level. Other features are shown by a variety of conventional signs symbols lines and patterns which are printed in appropriate colors and identified by names labels and numbers.

Contour lines also indicate the shape of the terrain. Where theyre close together they never intersect the elevation is changing rapidly in short distance and the terrain is steep. Forest agricultural land wastes sanctuary park school etc.

Joins points of equal height above sea level. Contour lines show relief and elevation on a standard topographic map. An area of land that sticks out like a finger from the side of a mountain or hill.

Essentially topographic maps represent the three-dimensional landscape of Earth within the two-dimensional space of a map. A Match the contour patterns on the left with landforms on the right. Standard colors for contour lines are brown red or.

Aretes and spurs are often generally referred to as ridges in backcountry recreation. A Match the contour patterns on the left with landforms on the right. Civil Engineering questions and answers.

Calculate the reduced level for each point using Rise and Fall method. Up to 24 cash back Spot Height. Ally represent elevations and laNdforms--the shapes into which the earths surface is sculp tured by natural forces--by contour lines.

A contour line represents an imaginary line on the ground above or below sea level. Indicating the direction of the stream flow. For this challenging task they had to produce a relief model with contour patterns and labels that indicate geographical landforms.
