Jupiter, Saturn, Uranus and Neptune are referred to as the Jovian Planets, or planets that are essentially big balls of gas, each are surrounded by many moons and rings.
Unlike Terrestrial Planets like the Earth, these planets lack solid surfaces and they have relatively small, dense cores that are surrounded by layers of gas, which is made mostly of hydrogen and helium.
Jupiter and Saturn is different from Uranus and Neptune because the first pair is made almost entirely of hydrogen and helium and some hydrogen compounds, while the latter pair are made primarily of hydrogen compounds with smaller traces of hydrogen, helium, metal and rock.
As for the planets' interior, both Jupiter and Saturn have layers of metallic, liquid and gaseous hydrogen extending outward, topped with a layer of visible clouds.
On the other hand, Uranus and Neptune have cores of rock, metal, water, methane and ammonia. The layer surrounding the core is also made up of hydrogen that is covered with a layer of visible clouds.
everything would eventually die. Humans could not live, build or expand.
The prime meridian and its opposite line, the antemeridian, divide the globe into the <u>Eastern and Western</u> Hemispheres.

It divides the world into the eastern and western hemispheres such that countries on the left are in the western hemisphere and those in the right are in the eastern hemisphere.
