What type of evidence found on Mars suggests that Mars may have been a warmer place and had a thicker atmosphere?
One piece of evidence is that there are many dry river channels in the martian Southern Hemisphere, like those found on earth. This suggests that water made these channels, and that means that at some point there was water on mars. Water means that the temperature was above 320F for at least some part of the year, and that it was humid enough so that the water would not instantly evaporate.

What evidence is there that water has been flowing on Mars recently?
NASA photographs of Mars are the best evidence that water has been flowing on Mars recently. During warmer periods in Mars' atmosphere, the photographs show streaks that look like streams. Scientists agree that this is evidence of water on Mars.
Why is the Earth's surface warmer than the surface of other planets like Mars?
The Earth's atmosphere traps heat.
Which planet is warmer than earth .. Jupiter or Mars?
Jupiter is much warmer than Mars. Jupiter's atmosphere contains gases that trap heat, creating extremely high temperatures throughout the planet. Mars, on the other hand, has a thin atmosphere that does not retain heat well, resulting in much colder temperatures.
Why is the earth warmer than the moon?
That's not necessarily a true blanket statement. The surface temperature at various places on the earth ranges between, let's say, -100 to +120 Fahrenheit (-88 to +50 Celsius). On the moon, the surface temperature on the 'night' side is about -240 F (-150 C), but on the 'day' side, it's about +225 F (+105 C) ... hotter than boiling water. The earth's atmosphere absorbs heat from the sun and distributes it around the planet. With no atmosphere on the moon, the surface takes full heat of the sun when the sun is up, and radiates it all away into space when the sun is down.
Are cloudy nights usually warmer or colder than clear nights?
Cloudy nights are usually warmer than clear nights because clouds act as a blanket, trapping heat emitted from the Earth's surface. This phenomenon prevents heat from escaping into the atmosphere, resulting in higher temperatures during the night.
What if the earth has a thicker atmosphere?
makes the earth warmer.
How can temperature be recorded from the ice cores?
If the ice core is thicker at certain areas, that suggests that it was warmer at that period of time. This is because when it is warmer, there is much more snowfall than when it is colder, and this snow compresses the ice, leaving it thicker and with less air bubbles.
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.
Does a basketball bounce higher in a colder atmosphere or in a warmer atmosphere?
Warmer atmosphere
Why does absorbing infrared make the atmosphere warmer?
Infrared are the radiations that contain heat. Absorbing them will make atmosphere warmer.
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.
What would happen if the insulating layer of carbon dioxide around the earth gets thicker?
There is no insulating LAYER of Carbon Dioxide round the Earth. The Carbon Dioxide is mixed up with the Oxygen and Nitrogen in Earth's atmosphere and is not present in the atmosphere as a layer. If the absolute amount of Carbon Dioxide in the atmosphere increases, the Earth would get warmer.
Why is mar's climate much colder than earth climate?
The main reason is that it is farther away from the Sun, and so light is less intense than on Earth. In addition, Earth has a thicker atmosphere which keeps it's surface warmer.
How can thick clouds keep us cooler in day and warmer at night?
the thicker the clouds the cooler they are
Does engine oil become thinner with extreme outside temperatures?
It is thinner when warmer, and thicker when colder.
