Obsidian changes into shale through weathering and compaction. Obsidian, an igneous rock, can get worn down into particles, usually through grind up against other rocks. Those tiny obsidian particles are then carried away by wind or water, and deposited in a river bed or out in the ocean. As time goes on, other sediments are then piled on top of the obsidian particles, compacting them down into shale.

Which rock is harder to sculpt granite shale obsidian slate?
Granite is the rock with the highest tenacity, and therefore the most difficult to sculpt. There are problems with the others, for a variety of reasons. Shale is fissile, and will split into thin sheets. Obsidian is glassy, and will be prone to fracture. Slate is prone to splitting along foliation lines, but would be the easiest to sculpt mechanically.
