Topographic Maps and Gradient

Gradient means..

• The slope/steepness

• The width

• Contour line

If the lines are far apart, it means it is a slow or ________________ rise/drop

• Gradual

• Steep

If the lines are close together on the map, it means that the rise/drop is ________________

• Steep

• Gradual

If contour lines are close together, then the slope is

• gentle
• steep
• flat
• going up and down

What are the curved lines on a topographic map called?

• contour lines
• contour intervals
• slope
• elevation

Determine the contour interval:

• 5 m
• 10 m
• 15 m
• 20 m

The gradient between location A and location B is approximately

• 0.04 ft/mi

• 25 ft/mi

• 40 ft/mi

• 50 ft/mi

What is the approximate gradient from point A to point B on the island?

• 1000 ft/mi

• 1250 ft/mi

• 2000 ft/mi

• 2500 ft/mi
