1. The house would be safe from flooding because the elevation of the land is more than 5 meters above sea level, which exceeds the flood level.
2. If the land were only 5 meters above sea level, the house would be at risk of flooding during high tide or storm surges, as water could reach the base of the house.
3. The contour lines on a topographic map represent points of equal elevation; closely spaced lines indicate steep terrain, while widely spaced lines indicate gentle slopes.
4. To determine if a house is safe from flooding, find its elevation on the map and compare it to the expected flood level; if the house’s elevation is higher, it is safer.
5. The contour interval is the vertical distance between adjacent contour lines, which helps in understanding the steepness of the terrain and calculating elevation changes accurately.
Parent Tip: Review the logic above to help your child master the concept of reading topographic maps worksheet.
