What do you know about the elevation and the slope? 

​Many maps are showing elevation but only Topographic maps are showing elevation in details for the whole area presented on the map.

​

​Elevation is the height of an object above the sea level. The elevation at the sea level is zero (0). Elevation is generally reported in meters or feet. Usually, elevation is shown by contour lines.

Multiple Choice

The height above sea level is called

• topographic

• contour

• elevation

• depth

Multiple Choice

What is the elevation of point B?

• 800 ft

• 850 ft

• 900 ft

• 1000 ft

Multiple Choice

Determine the contour interval:

• 5 m

• 10 m

• 15 m

• 20 m

Draw

​Slope

​

​The rate of rise or fall of a terrain feature is known as its slope. The speed at which things or people can move is affected by the slope of the ground or an area feature. This slope can be determined from the map by studying the contour lines.

​

​The closer the contour lines are the steeper the slope is. The farther apart the contour lines are the gentler the slope is.

Critical thinking: How the slope can affect hikers?

Multiple Choice

If contour lines are close together, then the slope is

• gentle

• steep

• flat

• going up and down

Multiple Choice

Which one is the steepest?

• 2

• 1

• 4

Multiple Choice

What do contour lines that are farther apart represent?

• waterfall

• steep area

• gentle slope

• river

Match

Match the following

• Contour lines close together

• Contour lines far apart

• Fall or a rise of a terrain

• The difference between the lowest and the highest point

• Zero meters
