### Equivalence relation on a continuum

Let $X$ be a continuum $=$ a connected compact metric space. Define $x\sim y$ if $x$ and $y$ are contained in a nowhere dense subcontinuum of $X$. It is easy to see that $\sim$ is an equivalence ...
### Prob. 6, Sec. 24, in Munkres' TOPOLOGY, 2nd ed: For a well-ordered set $X$, $X\times[0,1)$ in the dictionary order is a linear continuum [duplicate]
Here is Prob. 6, Sec. 24, in the book Topology by James R. Munkres, 2nd edition: Show that if $X$ is a well-ordered set, then $X \times [0, 1)$ in the dictionary order is a linear continuum. ...
