Why do scientists think that mars may have had liquid water on it at one time?

because it is in the goldilocks zone(habitable zone)
and they had a theory that mars had life MANY MANY MANY MANY yrs ago except that its gravity did not hold
Giant flood channels and tree-like networks of tributaries have been found on Mars. Furthermore, specific minerals such as hematite and goethite have been found, both of which sometimes form in the presence of water. Jarosite has also been found by the Opportunity lander in 2004 - this only forms in acidic water, confirming that water must have been around in the past.

∙ 15y agoThere are several reasons for this belief. One is the formation of microscopic rocks on the surface, which is usually an indicator. There are also grooves on the planets surface that appear to be dried up river beds. Also, the planet used to be much warmer. There are polar ice caps just like on Earth. It is believed there is enough ice in these caps to cover the entire planet of Mars in 11 meters of water if they were to be melted.

What planet do astronomers believe that there is a good chance of liquid water?
Mars scientists found water on. Mars
What do scientists think are the reason that there is no liquid water on mars now?
The reason why Mars has no water because its atmosphere is too thin, so the sun vapoured all the water on Mars and it does not have any plants to make it rain there.
Why do scientists think mars may have once been a warmer place and may have had a thicker atmosphere?
Scientists have proven that liquid water once existed on Mars. Currently Mars is too cold and atmospheric pressure is too low for water to remain liquid, so both temperature and surface pressure must have been higher.
Scientists believed it used to have flowing liquid water?
Scientist believe that the planet Mars used to have flowing liquid water. Now, the water on Mars exists almost exclusively as ice.
Did mars have liquid water?
no
What do scientists think are the reasons that there is no liquid water on Mars?
The reason why Mars has no water because its atmosphere is too thin, so the sun vapoured all the water on Mars and it does not have any plants to make it rain there.
Which planet thought to have liquid water in the past?
Mars. It has been explored by several unmanned land rovers in recent times. Evidence collected from these rovers has helped to build up a picture of Mars' past, revealing that Mars once had liquid water on its surface.

Why were scientists surpised to observe recently formed liquid water channels on mars?
Mars is too cold for liquid water to flow on the planet surface
Why do scientists think mars may have once been a warmer place and may have had a thicker atmosphere?
Scientists have proven that liquid water once existed on Mars. Currently Mars is too cold and atmospheric pressure is too low for water to remain liquid, so both temperature and surface pressure must have been higher.
Scientists believed it used to have flowing liquid water?
Scientist believe that the planet Mars used to have flowing liquid water. Now, the water on Mars exists almost exclusively as ice.
Why do scientists think that mars may have once been a warmer place?
Because its rocks clearly show that it once had oceans made of liquid water.
Why do scientists believe life may have existed on Mars?
We have found minerals and other formations on Mars that show it once had bodies of liquid water. As we currently understand it, liquid water is the most important ingredient for life.
Can water exist on a planet with no atmosphere?
Atmospheric pressure is an important factor in keeping liquid water on the surface of a planet. With no atmosphere, liquid water would quickly escape into space. It would depend on various factors such as the temperature and escape velocity of the planet of course. Scientists think liquid water existed on Mars in the past when the atmosphere was a lot denser. Water does exist on the surface Mars, but only as ice.
What forms of water are found in Mars?
There are traces of rivers but there has not been an actual discovery of water on Mars. Scientists think the water may be frozen underneath the polar caps.
How much of Mars has water?
Mars has no liquid surface water.
