Does Mars have actual soil, or is it just regolith, like on the moon?

You're right; there is an important distinction between soil (a matrix formed by the action of weather and running water - and, here on Earth, also by biological mechanisms) and regolith (which is merely the pulverized remains of meteor impacts.)

I'd say that, since Mars has weather, it is legitimate to refer to the Martian surface as being covered by soil.

Clay soil clumps together. That’s the problem

Thanks for clarifying that — soil, it is then.
