# Mountain stone

Brown angular stone etched with fine lines.

## What the simulation uses

- Holds water: 1 % by volume (Water it keeps after draining; the rest runs down to the drainage.)

- Pore space: 3 % by volume (Room for air and water between grains; low means roots suffocate when wet.)

- Weight: 2550 g/L (How heavy a litre is.)

- pH: 7 to 7.5 pH (How acid it keeps the soil.)

## Description
Brown angular stone etched with fine lines. Dense and nearly watertight, it leaves soil chemistry alone.

Also called landscape rock.

Estimated, where sources were thin: look authored for the app; physical values estimated.
