Steepest line possible dealing with slope is up to, but not including infinity.
Passive continental margins are not tectonically active, meaning there is no significant seismic activity or mountain-building processes occurring there. They are typically characterized by a wide continental shelf and a gentle slope leading to the ocean basin. Sediment accumulation is common along passive continental margins due to lower energy conditions compared to active margins.

The area with the steepest slope is the area where the contour lines are bunched closest together.
Antarctica has the steepest average slope of any continent, with much of its surface being covered by thick ice sheets that can create steep gradients.
I believe it is a cold front
No, active continental margins typically do not have a continental rise. Instead, they often have a steep continental slope that descends into a deep oceanic trench due to tectonic activity. Continental rises are found at passive continental margins where there is minimal tectonic activity.
The closer the contour lines the steeper the slope.
Passive continental margins are not areas of convergence. There is little volcanic and earthquake activity on passive margins. Active margins are areas of convergence where one plate is descending beneath another. They are associated with volcanic and earthquake activity.
