I'm debating with myself about what the best word is for a solid mass of uninterrupted homogeneous material. Usage would be as follows:
Example: That giant slab of granite on top of the mesa is _____; the whole thing is of one piece.
Counterexample: I can't say that brick wall is _____; it is made up of many separate pieces connected by mortar.
What would be the best word in the blanks there?
