Final answer:
Jupiter and Saturn are gas giants that are primarily composed of hydrogen and helium. Jupiter is recognized by its Great Red Spot and multiple moons, while Saturn is known for its prominent rings and thick atmosphere.
Step-by-step explanation:
Jupiter and Saturn are both considered gas giants, as they are primarily composed of hydrogen and helium. Their large size causes the gas in their interiors to become compressed and liquefied, making them more accurately referred to as liquid planets.
One characteristic of Jupiter that makes it easily recognized is the presence of the Great Red Spot, which is a massive storm that has been raging for centuries. Another characteristic is the presence of multiple moons, with Jupiter having the largest number of moons in our solar system.
One characteristic of Saturn that makes it easily recognized is its prominent rings. These rings are composed of vast numbers of individual particles orbiting close to the planet. Another distinguishable feature of Saturn is its thick atmosphere, which is composed mostly of hydrogen and helium.
