They can be any distance apart
It depends how far apart they are. It could be an infinite number.
When the contour lines are farther apart, this means that the slopes between them are gentle. On the other side, if the contour interval is smaller, the slope will be steep.
Contours for a gentle slope are spaced equally and far apart, the closer the contour lines the steeper the slope.
10 ft in the states and 30 ft apart 3 ft in Canada and 9ft apart. I'm not 100% sure about the Canada one :/
The land is relatively flat.
Contour lines that are far apart indicate gradual slopes, while contour lines that are close together indicate steep slopes.
On topographic maps, contour lines that are far apart indicate gentle slopes or gradual changes in elevation. The farther apart the contour lines, the flatter the terrain.

100 yards from tryline to tryline.
They can be any distance apart
Contour lines that are far apart indicate a gentle slope. Because contour lines connect points with the same elevation, wide spacing indicates that the elevation is not changing drastically.
they have to be close together if they are far apart it means it is a flat area

If the "contour interval" ... the elevation difference between lines ... is the same everywhere on the map, then the lines will be closer rogether on steep ground, and farther apart on flatter ground.
