Detailed explanation-1: -Not all planets are terrestrial. In our solar system, Jupiter, Saturn, Uranus and Neptune are gas giants, also known as Jovian planets. It’s unclear what the dividing line is between a rocky planet and a terrestrial planet; some super-Earths may have a liquid surface, for example.
Detailed explanation-2: -Terrestrial planets are planets made up of rocks or metals with a hard surface-making them different from other planets that lack a solid surface. Terrestrial planets also have a molten heavy metal core, few moons, and landforms such as cliffs, valleys, volcanoes and craters.
Detailed explanation-3: -Terrestrial planets (Earth sized and smaller) are rocky worlds, composed of rock, silicate, water and/or carbon.
Detailed explanation-4: -A gas giant is a GIANT planet that is made of gas! They are different from rocky or terrestrial planets that are made of mostly rock. Unlike rocky planets, gas giants do not have a well-defined surface – there is no clear boundary between where the atmosphere ends and the surface starts!
