It is produced by the movement of a glacier
i believe that you are talking about glacial striations
Because they are longitudinal waves. The direction of oscillation of the particles is parallel to the direction of propagation of the waves.

A irregular polygon will not have any parallel lines. :)* * * * *Not true. A rhombus is an irregular polygon and it has two pairs of parallel line!An irregular pentagon can have parallel lines.However, a triangle or a conic section cannot.
A rectangle, by definition is an irregular quadrilateral. It has two pairs of parallel sides.

Striations
Infinitely many. Every regular polygon with 2n sides has n pairs of parallel sides. Then there are irregular polygons which can have parallel sides. And there are also irregular shapes which have parallel sides.

Not normally unless it's an irregular heptagon which can be constructed to have parallel sides
As a regular 5 sided pentagon it has no parallel sides but as an irregular pentagon it can be shaped to have parallel sides.

The particles of the wave (for compressive waves). Or for transverse waves, yet the particles move parallel to the wave too.
On rocks - they are the parallel groves or scratches. Or on skeletal or cardiac muscle: they are the "strands" of the muscle.
A regular decagon will have 5 pairs of parallel sides, however, irregular decagons can have no parallel sides.
