Is a line necessarily straight?

Question: Is a line necessarily straight!?

I'm in college and I have art homework to do!.
We are making a mural and it will be called "Encyclopedia of line"!.
I have to make four 4" x 4" drawings that represent lines, as my art teacher said a line is "a trace of a movement through time"!. He also says that lines are found every where in nature!. The problem is, I'm not too sure what he wants me to do!. Is a line always straight!? Usually when you ask someone to draw a line they will make it straight!.!.!. Help!Www@QuestionHome@Com

In Euclidean Geometry, lines are straight!. You are in art class!.
I think your Prof!. wants something else,
In nature, "a trace of movement through time," might be
tree rings, fault movement, sand dunes, or ripples in a pond!.

The rings of Saturn show many "lines!."
Photos of Earth's rivers from space, layers of dirt along the Grand Canyon's walls, and the shiny trail of a snail show lines!.
They are everywhere!
