The same amount of matter is packed into a smaller space due to pressure compacting the shale into the metamorphic slate.
Explanation:
Density equals to mass divided by volume. Slate has the same mass as Shale but a smaller volume. The Shale minerals are changed by heat and pressure into Slate. The same amount of mass and the same minerals are changed and compacted into a smaller volume by the heat and pressure of the metaphoric processes.
Slate is more dense than Shale because it is more compact.
