Detailed explanation-1: -Earth is known as a watery planet. Almost 75% of Earth is covered by water in the form of a liquid state as well as in a frozen state. Hence, Earth is known as a watery planet.
Detailed explanation-2: -Structure. Neptune is one of two ice giants in the outer solar system (the other is Uranus). Most (80% or more) of the planet’s mass is made up of a hot dense fluid of “icy” materials – water, methane, and ammonia – above a small, rocky core.
Detailed explanation-3: -Oceans and ices and vapors, oh my! Turns out the Solar System isn’t so parched. Enceladus likely has a warm salty ocean, and liquid water lurks beneath the surface of Ganymede. The red planet Mars harbors evidence of being flooded by oceans and life forms, long ago.
