Maps

What do we need to know in order to read this map?

There are many different types of maps

Road Maps

Shows people how they can travel form one place to anotherShows where the __________ highways are and where small country roads are.

Shaded Relief Map

Shows the shape of the ________ - mountains, valleys, rivers and lakes

Topographic Maps

Show a _______- dimensional representation of a portion of the three dimensional surface of the earth.

What is a topographic map?

a map showing _____________ features, usually by means of contour lines.

___________ representation of the surface features of a place or region on a map, indicating their relative positions and elevations.

Land Height

Elevation- is the ____________ distance above or below mean sea level. Relief- is a representation of the __________ of hills, valleys, streams or terrain

CONTOUR LINES

• Contour lines join points on a map that are of equal height above sea level.

The houses are 50m above sea level.The deciduous trees are 100m above sea level.The coniferous trees are 150m above sea level.

How high above sea level is point X? _____How high above sea level is point Y? _____

On the above map, the highest point is shown with a dot.

This is called a _________ ______________.

Rules to Draw Contour Lines

1. A contour line must ___________ divide or split.2. A contour line must never simply ______. Somewhere the two ends of

a contour line must ______to enclose an irregularly circular region.3. A contour line must represent ______ and only ______ elevation. 4. A contour line may never ___________ other contour lines.5. Contour lines forms a __ pattern when crossing streams and it always

points ___________.6. Closely spaced contour lines indicate a ___________ slope; widely

spaced lines indicate a ___________ slope. 7. Concentric circles of contour lines indicate a ___________ or mountain

peak.8. Concentric circles of hashed contour lines indicate a ___________ or

closed depression.

Drawing Contour Lines

Where would the X and Y be on this map?

Where would the contour lines go?

Draw the 500m contour line

Draw the 400m, 500m and 600m contour lines

Can you recognize which set of contour lines match the profile view?

Contour Intervals

A set ______________ between contour lines on a map.

Ex. A 100 interval would mean that you have lines showing 100m changes in elevation between them.

So what is the contour interval for this island?

Contour Line Worksheet

1. Study the spot heights on the map below carefully. Use a contour interval of 50m and draw in the contour lines. This means you will draw the 50m, 100m, 150m and 200 m contour lines.

2. Draw in the contour lines using a contour interval of 50m on the 3 following maps. ** the 50m contour line is already completed on the first map.

3. Match the image with the contour line.
