Final answer:
No, Earth is not the only planet in our solar system with liquid water. Other bodies like Europa, Mars, Enceladus, and Titan also have water in different forms.
Step-by-step explanation:
No, the statement is False. Earth is not the only planet in our solar system with liquid water.
Evidence suggests that Europa, one of Jupiter's moons, has a large ocean of liquid water under its icy crust. This ocean is heated by the interior of Europa and may have active springs, similar to those found on Earth's deep oceans.
Mars also has a history of liquid water on its surface, and there is evidence for subsurface water and occasional surface flows. Enceladus, a moon of Saturn, has geysers that squirt liquid water into space. Although Titan, another moon of Saturn, is too cold for liquid water, it has hydrocarbon lakes and a thick atmosphere, making it an interesting place to search for alternative forms of life.
