yes because science shows that there are plants there and it needs water to grow
ice burgs are found on it.
There is no liquid water on the moon. There is some evidence that there is frozen water.
Evidence on Mars such as dried-up riverbeds, mineral deposits that form in the presence of water, and the presence of ice caps suggest that liquid water may have existed on the planet in the past. Additionally, recent discoveries of hydrated minerals on Mars provide further evidence that water played a significant role in the planet's history.
Mars' atmosphere contains trace amounts of water vapor, and it has polar ice caps that contain frozen H2O.
There is evidence of ancient river valleys, lake beds, and mineral deposits on Mars that suggest the presence of liquid water in the past. Additionally, recent discoveries of recurring slope lineae (dark streaks on Mars' surface that appear to flow downhill) suggest the possibility of salty water flowing on the planet today.
Mars' atmosphere contains trace amounts of water vapor, and it has polar ice caps that contain frozen H2O.
Evidence suggesting that Mars may have once had liquid water includes the presence of ancient river valleys, lakebeds, and mineral deposits that typically form in water, such as clays and sulfates. Additionally, spacecraft have captured images of features resembling river deltas and possible shorelines, indicating past water flow. Analysis of Martian soil and rocks also reveals hydration, further supporting the idea that liquid water existed on the surface in Mars' early history.
Only Earth is thought to have liquid water.===================================Updated informationIn 2015, NASA presented what they consider definitive evidence that there is some liquid water on Mars.
Europa, one of Jupiter's moons, is considered likely to have a deep subsurface ocean of liquid water. The moon's icy surface shows evidence of geological activity, suggesting the presence of a hidden ocean beneath the ice.
water vapor condenses to form liquid water
There is evidence that there was once water on Mars due to large gullies on its surface. This may suggest that running liquid water may have eroded it away and the fact that Mars has 'frozen' ice caps may suggest that it was once liquid water that had frozen over a large period of time.
The evidence that the liquid obtained from the copper(II) sulfate pentahydrate was water is that the colorless liquid did not change color or show any sign of chemical reaction when exposed to air. Additionally, the liquid evaporated over time, leaving behind white crystals, which is consistent with the properties of water that can be driven off as vapor.
