They have different rotations, different distances from the sun and earth. Different amount of moons, gases, and temperatures.
Hope this helps!! :)
why
gas giants are composed of gas while terrestrial planets are composed of solid matter
Each of the gas giants is surrounded by rings made up of dust, rock, and ice particles.
A sentence for gas giants is: There are four gas giants in the solar system, which are Jupiter, Neptune, Saturn, and Uranus. Another sentence is: The gas giants are mainly composed of various different gases.
The Gas Giants have a deep gas atmosphere and earth have a not so deep atmosphere
helium, with traces of other gases like methane and ammonia. These planets have thick atmospheres that consist of several layers, each with different compositions and properties. The presence of hydrogen and helium in the atmosphere contributes to the large size and low density of gas giants.
Gas giants all share the same characteristic. 1.) they are composed of hydrogen and helium, and they may contain some methane (Uranus is a planet that contains methane, also the reason why it has a blue-green appearance) so there is a possibility that some of the gas giants contain methane. It is technically the reason why they are called gas giants.
neptune is the third bigest planet from the solar system
Because since they are so far away from the sun, the gases on their surfaces are frozen solid. They are definitely gas giants, but are also made of ice. Some people may even call them ice giants
The ice giants are Uranus and Neptune. Previously they were classified as gas Giants, but since the voyager flypasts it was noted that they has a completely different structure to the other gas giants (Jupiter and Saturn) Whereas Jupiter and Saturn are composed of mainly hydrogen and helium, Neptune and Uranus are composed of a rocky core surrounded by a "slush puppy" solution of ice and methane.
Uranus rotates on its side
