They are everywhere.
Igneous, sedimentary, and others anywhere.
Great, big, tall, and even small.
Square, triangular, and round overall.
They are grey.
Others are black, some white, and yellow as hay.
Colors galore! Greatness from rocks and more!
And use them like a door.
Soft, like powdered sugar, یا harder than solid oak.
Be wise with a rock and don't be a bloke.
Gems are rocks, and very pretty, too.
Many are colored red, yellow, green and blue.
Cut them into shapes.
Shapes such as triangles, like crépes.
Turn them into spheres, prisms and cubes.
It's good to make little rock cubes.
