Calculate Gradients

How can you analyze changes in elevation? Gradient refers to the steepness of a slope. To measure gradient, divide the change in elevation between two points on a map by the distance between the two points. Use the map to answer the following questions, and convert your answers to SI units.

Analysis

1. Determine the distance from Point A to Point B using the map scale.

2. Record the change in elevation.

3. Calculate If you were to hike the distance from Point A to Point B, what would be the gradient of your climb?

Think Critically

4. Explain Would it be more difficult to hike from Point A to Point B, or from Point B to Point C?
