* Planets form from dust and gas: Planets form from vast, swirling disks of gas and dust called protoplanetary disks around young stars. These disks are not clouds, but rather dense collections of matter.
* Gravitational attraction: Gravity pulls together the particles in the disk, causing them to clump together. These clumps grow larger over time, eventually becoming planet-sized objects.
* Clouds are water vapor and other particles: Clouds on Earth (and other planets with atmospheres) are made of water vapor, ice crystals, and other particles suspended in the air. They are temporary formations that dissipate or change shape depending on temperature, air pressure, and wind.
In summary: Clouds are atmospheric phenomena, while planets are celestial bodies formed from dust and gas through gravitational accretion.
