because those are the 2 planets closest to the sun
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.
no
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.
Salty water has a lower freezing point than pure water. So, very salty water may have a chance of being liquid on Mars. However there seems to be no liquid water on Mars.
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.
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.
Because on Mars it is too cold so any water on the surface is frozen, while on Venus its too hot.
The Rover mission confirmed that Mars once had liquid water on its surface.
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.
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.
No. They are two hot because they are too close to the sun and don't contain water, frozen or liquid.
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.
Mars has no liquid surface water.
There is no liquid water on Mars.
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.
There is no liquid water now on Mars. There may have been, in the past. Also, there is ice on Mars.
They had found ice on mars but no sign of a liquid
