Vertical first.
Yes, intervals can be either on the Y Axis (Vertical), or the X Axis (Horizontal).
On a map that shows only a small part of the Earth's surface, the coordinate gridlooks like Cartesian " X and Y " coordinates. But as the map shows more and moreof the Earth, it starts to become apparent that the "lines" of latitude and longitudeactually represent polar coordinates on a sphere of constant radius.On a map that's sufficiently accurate, your first clue is this: Carefully measure thedistance between two of the 'vertical' lines, at the bottom of the map, and thenmeasure the distance between the same two lines at the top of the map. The twomeasurements are slightly different, because on a map of the full Earth, the 'vertical'lines all meet, at the north and south poles.
Open interval does not include its end points while closed interval includes
the ratio between the vertical interval and horizontal equivalent is defined as the gradient.
Not necessarily but yes, it can be. A contour interval is the difference in elevation between successive contours, while a vertical interval is the distance between any two contours. So yeah, it can be the same sometimes.

A contour interval for a given topographic map always the same is true; not false.
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.
The Relationship between the relief of an area and the contour interval on a map of the area is A contour line
?
Contour lines show elevation on a topographical map. These lines connect points of equal elevation above sea level, with lines close together representing steep terrain and lines further apart indicating gentler slopes.
Vertical first.
That's the vertical lines.
The difference in elevation between the highest and lowest contour lines on a topographical map is called a contour interval.
