The entire crust, including the volcano, sort of “floats” on the Mantle.

The Mantle isn’t quite liquid, but it’s not quite solid either. It’s highly viscous molten rock under considerable pressure. It “flows” over very long time scales but you couldn’t swim in it.

Think of it like really thick tar. You could walk on it, but it’s not solid.

The asthenosphere, which makes up most of the mantle, is mostly solid. It's squishy, but solid.

It's liquid enough to circulate somewhat, dragging the more-solid slabs of the lithosphere around the surface of the Earth.
