Contour lines **generally do not meet or intersect**.

Answer and explanation: Contour lines never cross on a topographic map because **each line represents the same elevation of the country**.

Contour lines also **never touch or overlap, except in certain rare cases** such as: when there is a vertical or overhanging cliff.

Explanation: Two contour lines of different heights cannot intersect. However, contour lines of different heights can only intersect at **an overhanging cliff and a cave**.

Contour lines that are very close together indicate **a steep slope**. The figure above shows various topographical features.

- Contour lines always separate points of higher elevation (uphill) from lower elevation (downhill).
- Contour lines never cross or intersect.
- Contour lines never divide.< /li>
- Contour lines always combine into a shape, usually an irregular circle.

Answers. **Two contour lines never intersect** because each line represents a separate height and we cannot have two different heights at the same point.

Contour lines **connect points of the same elevation**: Where they are close together (they never intersect), the elevation changes rapidly over short distances and the terrain is steep. Where contour lines are widely spaced, the elevation changes slowly, indicating a gentle slope.

**Contour lines do not cross, divide or divide**. 2. Closely spaced contour lines represent steep slopes, while widely spaced contour lines represent gentle slopes.

The slope between contour lines is assumed to be uniform. The distance between the contours indicates the steepness of the slope. **Irregular contours mean rough, rough country**. Smooth lines imply gradual gradients and changes.

Rule 3 – **Contour lines do not touch or cross, except on a cliff**. Rule 4 – every 5th contour line is colored darker. This is an INDEX contour line. Rule 5 – Contour lines are closer together on steep terrain and farther apart on flat areas.

The contour lines can only cross each other on the map if. **Electrical Engineering** for all AE/JE exams – mini mock test. Vertical cliff: Contour lines of different heights unite to form one line. Rock overhang: Two contours of different heights intersect here.
