Why does earth a liquid water supply an Venus does not?
Venus is closer to the sun, so it's hotter there. Water needs to stay below 100 deg C to remain a liquid, and Venus is hotter than that.
Is earth the only known planet with a hydrosphere?
As of now, Earth is the only known planet with a stable, extensive hydrosphere, characterized by large bodies of liquid water on its surface. While some other celestial bodies, like Europa and Enceladus, are believed to have subsurface oceans, they do not possess a hydrosphere in the same way Earth does. Mars has evidence of past water flow and polar ice caps, but it lacks a significant, stable hydrosphere. Thus, Earth remains unique in its abundance and stability of liquid water.
Did mars have liquid water?
no
Do planets have hydrosphere?
No. There are no oceans, rivers, or lakes on Venus. All of the liquid water on Venus was apparently lost long ago. The solar radiation disassociates water, and the hydrogen was blown off by the solar wind, because Venus has practically no planetary magnetic field. There is still a tiny percentage of water vapor bound as sulfuric acid (rain) in the sulfur dioxide clouds around the planet.
Why can't there be liquid on Mars?
There is liquid on Mars, frozen liquid that is. On the poles of Mars are two ice caps, and guess what ice is made of? That's right water, which is liquid. I don't know who told you there couldn't be liquid on Mars but they are wrong.
What is the hydrosphere of mars?
The hydrosphere of Mars refers to all the water on or near the planet's surface, including liquid water, ice, and water vapor in the atmosphere. Currently, Mars has frozen water ice caps at its poles, as well as water ice and vapor in its thin atmosphere. There is evidence of ancient water flow on Mars, suggesting that liquid water was once present on its surface.
Why is there no liquid on the surface of Mars and Venus?
Because on Mars it is too cold so any water on the surface is frozen, while on Venus its too hot.
What does earth have that mars and Venus doesnt?
Earth has abundant liquid water on its surface, a protective magnetic field, and a thick atmosphere that creates stable temperatures suitable for life. Mars lacks a significant atmosphere and water in liquid form, while Venus has a thick toxic atmosphere with extremely high temperatures.
Which inner planet once had water on it?
The Rover mission confirmed that Mars once had liquid water on its surface.
Why does earth a liquid water supply an Venus does not?
Venus is closer to the sun, so it's hotter there. Water needs to stay below 100 deg C to remain a liquid, and Venus is hotter than that.
Is there life on venus mars and mercury?
No. They are two hot because they are too close to the sun and don't contain water, frozen or liquid.

Did Venus once have running water?
There is no known evidence of liquid water every having existed on Venus, but it is quite possible that surface conditions were once very different from what they are now. Note that the surface of Venus has not been studied as extensivley as the surface of Mars.
Which planets have 70 percent covered with water?
Earth.The Earth is about 70% covered with water. We can't be too sure about other planets, although Mars and Mercury are certainly dry, and Venus is too hot for water to remain liquid.
How much of Mars has water?
Mars has no liquid surface water.
Does the water on Mars flow slowly?
There is no liquid water on Mars.
Where might water exist as liquid on Mars?
There is no liquid water now on Mars. There may have been, in the past. Also, there is ice on Mars.
