How was Mars was once similar to Earth?
We now know that Mars once had liquid water on its surface and probably had a much denser atmosphere than it does now.
What inner planets once had liquid water on its surface?
Mars
What proves that Mars once had a warmer climate?
Analysis of the rocks on Mars show that its surface once held liquid water. Mars is too cold for water to remain liquid now, so it must have been warmer in the past.
What evidence suggests that liquid water is or once was present on mars?
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.
Why would dry riverbeds suggests mars once had a warmer climate?
Currently, Mars is too cold for liquid water to exist on its surface. Dry river beds suggest that liquid water once flowed there.
Which inner planet once had water on it?
The Rover mission confirmed that Mars once had liquid water on its surface.
Is there evidence of mars having liquid water?
yes. there is water underground and scientist believe mars once had streams, lakes, and an ocean
What evidence shows that mars once have liquid water?
ice burgs are found on it.
What planet once had liquid water?
Scientist are thinking Mars, because of river beds there.
Which planet thought to have liquid water in the past?
Mars is the planet thought to have had liquid water in the past based on various geological features such as canyons, river valleys, and mineral signatures found on the surface. These suggest that Mars likely had a more hospitable environment billions of years ago where liquid water could have existed.
What planet has evidence of erosion by water?
Mars has evidence of erosion by water, including river valleys, channels, and minerals formed in the presence of water. Mars once had liquid water flowing on its surface, shaping the landscape over time.
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.
