It's a disc (or disk).
No. The disk between the vertebra is like a sandwich. It has a filling that we call a disk. If the disk is pushed out a little bit, it is called a budging disk. If it comes out most of the way or all the way, it is a ruptured disk. This is more serious as it can push on the nerves so much so that you will need surgery. The other can sometimes be treated by physical therapy but it can get worse and rupture.
Saturn is the largest planet known to have many rings. Its iconic ring system is composed of different types of particles, ranging in size from tiny grains to large boulders, which orbit the planet in distinct bands.
Planet formation occurs through the process of accretion, where dust and gas in a protoplanetary disk clump together to form planetesimals, and eventually planets. Gravity plays a crucial role in this process, pulling material together to form larger and larger bodies. Over time, these planetesimals collide and merge, forming planets.
Perhaps the intent of the question is to describe a black hole's accretion disk. Matter falling onto a black hole can form an accretion disk heated by friction, forming some of the brightest objects in the universe. These bright objects are indicative of nuclear meltdown due to the stretching and compaction of matter as it nears the event horizon.

A disk of matter that circles a planet and consists of numerous particles in orbit that range in size from a few millimeters to several hundred meters is known as a planetary ring. These rings are commonly found around gas giants like Saturn and are made up of dust, rock, and ice particles orbiting the planet in a flat, thin disk.
Concentric circles, are circles within circles. Each concentric circle on the surface of a disk represents a track, the narrower the circle is, the more data can be stored on the disk.

A precursor to a planet. You could also call it an early stage in the formation of planets.
true
ballsack
Track on afloppy disc
hmmm mabye the call of duty 2 disk
