It is also a fact of great importance that the water which flows down from above, and atmospheric humidity, are available to the mosses of basalt surfaces only as long as the water is flowing or is deposited, while the tuff is able to absorb water through its porose surface, and thus has a constant supply of necessary moisture for the vegetation. Owing to the slight power of resistance of the tuff against the ero-.
