A rift valley is, of course, a valley.  It is long and and relatively straight.  It runs between two ranges of mountains.  The way that rift valleys are formed is by the spreading of geological faults.  In other words, a rift valley is formed by the two sides of a fault pulling apart.

Geologically speaking, there are many different kinds of right valleys.  In other words, they can be caused by a variety of geological processes.  But in general, they are all caused by the crust spreading apart and breaking, with the middle part dropping to form the valley.
