Why do giant planets have rings?

The rings are made up of dust grains, grains of sand, and larger bodies formed when meteorites collide with satellites of giant planets and subsequent collisions with each other. These fragments gradually settle on the planet, and therefore the amount of matter in the rings decreases over time.
