Only Earth has (in our solar system). That's what makes it so special.

MARS
The Earth is sometimes called the "Blue Planet" or "Water Planet" because it is the only known planet that has large amounts of liquid water. Water bridges the gap to life, so water makes it possible for the Earth to support life.
The Earth is Blue or the bio planet. The Earth is known as Blue planet because most of its surface is covered with water.
Earth is known as the blue planet because its surface is 75% water, which happens to appear blue.
The question seems poorly worded, but Earth is the planet with liquid water on its surface.
Some do. Earth is the only planet known to have liquid water. Mars has ice at its poles and beneath its surface in some places.
Ice and Glaciers
The surface of planet Earth is made up of 71% water.
not on the surface but might be some under the surface of the planet...??
