In this paper we consider
the partial ordering induced on 1-dimensional continua by quasi dimension type. For
example, we show that the pseudo-arc precedes every snake-like continuum in this
partial ordering. We also obtain sufficient conditions in terms of quasi dimension type
for the embedding of Peano continua in the plane. Finally, necessary and sufficient
conditions in terms of quasi dimension type are given for a continuum to be tree-like
and to be 1-dimensional.
