The correct label for the arrow from the picture of obsidian (an igneous rock) to the picture of slate (a metamorphic rock) would be:

**heat and pressure**

This is because the formation of metamorphic rocks from existing rocks (in this case, changing the conditions of igneous rocks like obsidian) typically involves heat and pressure.
