What you will learn

A contour joins places at the same elevation. With equal map scale and contour interval, closer lines represent a steeper slope.

Words to use

  • contour: line of equal elevation
  • elevation: height relative to a stated reference
  • slope: how steeply ground rises

Work through the activity

  1. 5 min · Read a lineImagine two points on a contour labeled 100 ft. Explain why both are at the same elevation even if far apart along the line.
  2. 15 min · Compare spacingOpen Topo Lab question 1 or draw five close lines and five widely spaced lines. State that both panels use the same scale and interval.
  3. 10 min · Read a hillDraw nested closed contours labeled 100, 120 and 140 ft increasing inward, with no depression marks. Describe the land shape they suggest.
  4. 10 min · Explain to a partnerUse the words elevation and spacing in your explanation. Identify what the simple drawing does not tell you about trails or safety.

Grade 4 · Contour Lines for Beginners

Learning goal: Explain equal-elevation lines and compare slope spacing on maps with the same scale and interval.

Expected responses

  1. The same elevation.
  2. Close lines, when scale and interval are the same.
  3. A hill rising toward the center under the stated no-depression assumption.
  4. No. Trail conditions, access, terrain hazards and more information are needed.

Understanding check: the same elevation. Contours show elevation. They do not establish equal travel distance.

Watch for this misconception

Spacing comparisons require a shared scale and contour interval.

Assess the evidence

Look for the observations, calculation or explanation named in the learning goal. Accept accurate drawings and dictated responses. Use the expected responses to discuss reasoning; a correct guess without explanation is a starting point for another conversation.

Adapt and extend

Read prompts aloud, enlarge print or let a partner record the learner’s explanation. Complete the remaining Topo Lab questions with a partner.
