Group Q The Gas Giant Planets

unlike terrestrail planets the gas giants are made from gaseous composition, such as hydrogen and helium. they do have some rocky material, although it is mostly in the planets core. the four gas giants are neptune,uranus,jupiter and saturn. jupiter and saturn are mostly made up from hydrogen and helium, whith heavier elements making up between 3 and 13 percent off mass. they are thought to consist of an outer layer of molecular hydrogen surrounding a layer of liquid metalic hydrogen, with a molten rocky core. the outermost layer of their hydrogen atmosphere is charicterized of many layers of visible clouds that are mostly composed of water and amnonia. the layer of metalic hydrogen makes up the bulk of the planet, and is reffered to as "metalic" because of the very large pressure turns hydrogen into an electrical conducter. the gas giants core are thought to consist of heavier elements at such high temperatures and pressures that their properties are poorly understood.

facts about gas giants
- the gas and ice giants take longer to orbit the sun because of how far away they are.
- the densities of gas giants are much less than the densities of the rocky, terrestrials of the solar system world.
- gas giants aren't all made of gas.
- uranus has an icy layer over its solid rock core and covered with a gaseous atomosphere.
- the metalic hydrogen in jupiter and saturn conduct electricity.
- all gas giants are in the solar system are outer planets.
- jupiter is the biggest planet in the solar system.
