Earth is the only known planet with liquid water.
Because on most planets (mars being an exeption as there are places where water can stay liquid) temperature and/or atmospheric pressure is to high or low for water to stay liquid.
Mars
Earth!
None of the planets in our solar system except Earth are thought to have surface liquid water in any considerable amount. Some planets are known to have water ice or atmospheric water vapor; some moons of Saturn and Jupiter (which are not planets) show evidence of having sub-surface oceans of liquid water owing to tidal heating effects; other planets including Mars and Venus (both of which were thought to have significant amounts of surface water in their history) continue to be studied for the possibility of liquid water below the surface.
earth is the only planet known to house liquid water and life
Sure There are planets in our solar system that have 100% liquid surfaces, why not water.
Earth. Cause you can look on a planet map and earth is the only one with blue on it..
Liquid water is an indicator that there is probably life present.
Earth is just the right distance from the sun, receiving just enough energy to allow liquid water to exist on the planets surface. If earth were a little further away, then the water would be frozen as ice, while much closer and the water would boil away as water vapour. Liquid water is essential for allowing life to exist.

The earth is in what astronomers call the 'Goldylocks Zone': Just the right distance from our sun that liquid water can exist.
