River Valleys and Spurs
Rivers flown inside of Valleys
Ridges of land are called spurs
Spurs seperate valleys
Contour lines indicate a valley by making a
V
shape that points
Uphill
Contour lines represent spurs by making a
U
shape that points
downhill
Contour Lines
We represent rises and falls of the earth on flat paper using contour lines
Contour lines join places of equal height that are above sea level
They are good at showing relief because they show shape, size and steepness of all features
Height and Contours
Trigonometrical Beacons
These occur at the highest point
They show the height and Code of the trig beacon
Spot Height
These are small dots that are next to a specific place on the map
The exact altitude is recorded there
Bench Mark
Evident along roads or highways
The exact altitude is printed next to the beacon
Steep and Gentle Slopes
Contour lines that are close together show
Steep slopes
Contour lines that are further apart show
Gentle slopes
Scale and Distance
We use the scale to show how far a place would be in the real world by using a map
You must use conversions to figure out the distance in
M or KM
