The elevation of a point that falls between two contour lines can be approximately determined by averaging the elevation of those two points. Assuming the point is somewhat halfway between the lines, this can be done by adding the elevations and dividing by two.
Granite would be the better choice simply becaue it
On house, why might a pyramid-shape roof be better than a flat roof?
A better name for "corners" would be angles, but the shape's name would be a hexagon
The 'better' stone would be a combination of its other attributes: colour, cut and clarity, in addition to its carat weight, which you state.
It depends on the scale of the map. If it is a trecking map then 5 m, but for driving maps or similar, 30m contours would be fine.
Notice the pattern around that contour line. Then determine the interval that the surrounding contour lines are increasing or decreasing by. Ex. 50 100 150 200, the contour interval would then be 50
A 1-meter contour interval would be more likely to show a shallow 1.5-meter-deep depression in the ground. A 5-meter contour interval would smooth out such shallow features, making it harder to identify them on the map.
A topographic map of the Great Plains would typically have a small contour interval. This is because the region is relatively flat with subtle changes in elevation. A small contour interval helps to accurately depict these gradual elevation changes on the map.
Two successive index contours on a map would be 5 meters apart. The interval is how far apart two contour lines are, so since the contour interval is 5 meters the answer is 5 meters.
A map of the Rocky Mountains would have a small contour interval because of the multiple peaks and ridges and the constant increase of elevation.

The height between contours is usually stated in the map's legend. For instance, on an Ordnance Survey (UK) 1:50 000 Landranger Series, contours are at 10 metres vertical interval.
With eight contour lines that follow the upward elevations in increments of 10 feet.
You would just add 10 every contour line you pass until you get to the number 80.
Contour maps show elevation. The contour interval tells what the difference is between each contour line is, so lines closer together means a steeper slope, and further apart means a gentler slope.
It would be the difference between the two darker lines, or index lines, and then divide the space in between with your difference.
