The question seems poorly worded, but Earth is the planet with liquid water on its surface.
Only earth.
Ours - Earth.
Definitely. Out of every planet in our Solar System, Earth is the only one with liquid water on its surface.
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.
About 70% of the surface of the Earth is covered with water but only about 0,0001% of the total mass is liquid water.
Earth is the only known planet to have oceans of liquid water.
Atmospheric pressure is an important factor in keeping liquid water on the surface of a planet. With no atmosphere, liquid water would quickly escape into space. It would depend on various factors such as the temperature and escape velocity of the planet of course. Scientists think liquid water existed on Mars in the past when the atmosphere was a lot denser. Water does exist on the surface Mars, but only as ice.
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.
Earth is the only planet that is the right temperature to support liquid water on its surface. All the others are either too hot or too cold.
Earth. Cause you can look on a planet map and earth is the only one with blue on it..
Earth is the only one we know of so far :)
At the moment, the only planet known to have any significant "liquid" water, is the Earth. But it's only the surface that is 70% water. Overall, it's a mere nothing. See the related link for a picture of all the water on Earth.
