How can you tell a steep gradient on a topographic map? ::
The gradient is steepest where the isolines are closest
together.
::
The gradient is steepest where the isolines are farthest
apart
::
You can't tell by just looking. You need to calculate
gradient mathematically
:: Gradient shouldn't even be a thing in 2020.
