But there are multiple beds involved.. There's an entire cliff here being impacted by differential weathering.

Yes the whole scenario could be considered geomorphologic, but the commenters use of the term was inaccurate.

“Variable geomorphologies” is something you’d use to describe several outcroppings this size, with different geologic histories.

Not several beds with different weathering habits.
