Earthen building techniques are all fairly closely related.
When you bake your units in the sun and then stack them into a wall, you call that
adobe.
Unless you made the units stick together by compressing them, in which case they're
CEBs, Compressed Earth Blocks.
When you pile your mud into a wall and let it dry in place, that's
cob. (Occasionally, and only in the US Southwest I think, it's "coursed adobe" or "puddled adobe".)
But when you get your wall to hold together by compressing it, that's
rammed earth.
I love them all.
