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.
The planet that was once warmer like earth is Mercury?
No, Mars.
What animal could live on Mars?
No animal could live on mars as far as scientist know scientist have sent out the opportunity and spirit rovers that found ice which proves that there was once water on mars
Does the soil on mars have potassium in it and turns it red?
Its evidence proves that it once had oxygen and it has iron, the iron rusted to make the red
What proves that mars is alive?
Currently there is no proof or even strong evidence of life on Mars. Analysis of minerals has proven that there was once liquid water, and some chemical evidence suggests that there were once complex organic compounds. This means that Mars might have once supported life, but again, there is no solid evidence.
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.
What makes us think that mars must once have had an atmosphere that was warmer and had higher surface pressure?
Evidence such as dried-up river channels, minerals that form in liquid water, and a thin layer of atmosphere around Mars suggest that it once had a thicker atmosphere and higher surface pressure. Additionally, features like valleys and lake beds further support the idea that Mars may have had a warmer and wetter climate in the past.
Giant fossil ferns have been found in Canada Which conclusion can be drawn from this discovery?
Canada once had a much warmer climate.
Which discovery may have provided evidence that the climate in Antarctica was once much warmer than it is today?
Lava flows in Antartica
One fact about planet mars?
Besides the fact that temperatures get as low as -87°C (that's pretty "cool"), there is the fact that Mars was once warmer, had a thicker atmosphere and had plenty of liquid water flowing on it.
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.
What phenomena confirms life on mars?
None, there is no life on Mars at this time. However evidence that Mars once may have had flowing water in some areas, suggests that it might briefly have had life for a short period of time, a couple billion years ago before losing this water. However there is nothing that proves that Mars actually had life at any time.
