I'm not entirely certain what this question is even supposed to mean. It's not perfectly flat, if that's what you're asking. However, it's also not a uniform gradient... like any other country, it has varying terrain.
It is its slope or gradient.
The relation is that gradient and slope are both angled lines.
The slope of a line is its gradient
The other term for slope is gradient
Gradient is the steepness of a slope.
Gradient is the steepness of a slope.
The gradient of the tangents to the curve.
Gradient
a steep slope
low slope and gradient are the same thing - just measured in different units
Gradient (slope) = 6
Slope or gradient = (y2-y1)/(x2-x1)
