I liked it when the discussion touched the rocks and their being alive.
For a stone that one keeps on the mantel piece or Florence poole in her parents'garden or for
Michelangelo's Pietà Rondanini, their "life" manifestations are mostly in the effects they have in the people that look at them, touch them, that use them as sources of stimula that belong to an high sphere of thought.
A quality of stones
Larger stones
Spoiler:
Things are different if one consider a larger stone, like our planet. The almost totally passive nature of the stones in the preceding examples, changes radically. Almost I said, thanks to that expressive quality.
Earth is very active. It is a very common point of view for us humans to consider of Earth only that tiny layer that includes the atmosphere and the surface of Earth. The atmosphere occupies just 3% of the radius of Earth, and only 3 parts over 100,0000 of its volume. More or less like the skin of a peach. In terms of mass that part of Earth that we humans consider is even smaller than that, as the density increases maybe 10 fold going down toward the core of Earth.
Earth is more or less made like the slab of granite that I use as a table in my garden, with the exception of the core that is made by heavy material, mostly dense metals. It changes, with respect of my table, the physical state, my slab is solidly solid, Earth interior can be fluid, because of the different conditions of temperature and pressure. So much for geography 1001.
Earth is very active. An enormous amount of energy is involved, that is exchanged between the various parts (organs) of Earth , its external layers and the surrounding space through amazingly articulated mechanisms and manifestations. Geoscience is a relatively new branch of knowledge, but extremely active and in continuous growth.
