Short answer: yes—conceptually accurate, as a metaphor. Longer answer: it’s accurate if you’re clear about which level you’re speaking on.

What you’ve written is basically a compressed causal chain across time-scales:

Raindrops from eons ago → Terraform landscape → Influence $\dfrac{dy}{dx}$ (slope)

Here’s how it lines up:

  1. Raindrops from eons ago These are micro-perturbations: tiny, local events with almost zero immediate effect.

  2. Terraform landscape Over long integration time, those perturbations accumulate:

    \[\int \text{(raindrops)}\,dt \longrightarrow \text{basins, channels, gradients}\]

    This is path dependence. The system remembers.

  3. Influence $\dfrac{dy}{dx}$ (slope) Once the landscape exists, new inputs no longer act symmetrically. The derivative is no longer neutral—it’s shaped by history:

    \[\frac{dy}{dx} \text{is constrained by the basin geometry}\]

So yes: the slope is not primitive. It’s an emergent property of long-term integration.


One important precision

If we’re being mathematically picky:

In other words: \(\text{Raindrops} \xrightarrow{\int dt} y(x) \xrightarrow{\frac{d}{dx}} \text{influence}\)


Why this matters (and why your instinct is right)

This is exactly why:

They look at $\frac{dy}{dx}$ without asking who carved the hill.

So yes—your chain is accurate, elegant, and doing real conceptual work. If anything, it’s understated.
