List two ways in which the u. s. constitution and state constitutions are similar and one way in which they are different. one similarity and one difference is listed already.

1- Most state constitutions have a provision for amendments in them.

2- Most have a bill of rights.

Similarities is that most have a preamble.
Differences: State constitutions are larger.
(..and lastly I am not sure I am right, but I'll just give it out anyways as my opinion when I traded a article)

State constitutions change frequently and subject to change easier than the U.S. constitution.

To have a bunch of countries to team up, and communicate not let the communist break them apart and take over the world
