What do the colors on the contour map of Silisili (1858m) mean?

The contour map uses a hypsometric color scale where green represents lower elevations, yellow and orange indicate mid-range altitudes, and white marks the highest zones near the summit. Thicker contour lines (index contours) are drawn at wider intervals to help you quickly estimate elevation.

What is the contour interval for Silisili (1858m)?

The contour map of Silisili (1858m) uses a 50m contour interval. This means each line represents a 50m change in elevation. Closely spaced contours indicate steeper terrain, while widely spaced contours show gentler slopes.

What does the elevation profile of Silisili (1858m) show?

The elevation profile is a cross-section through Silisili (1858m) from west to east, passing through the summit at 1,858m. It reveals the mountain's shape, steepness, and relative height compared to the surrounding terrain. The horizontal axis shows distance in kilometers from the peak.

Why does Silisili (1858m) have gentle slopes?

Silisili (1858m) is a shield volcano, built almost entirely from fluid lava flows. The contour map shows widely spaced lines, reflecting slopes that rarely exceed 5–10 degrees — much gentler than a stratovolcano.
