What do you mean such dry ice is doubtful? There are satellite images of it.


As Egyptians say: Light on you :)

So there are satllite images which aren't enough to differentiate between dry ice and water ice.

Touche, but seriously...


Ya, actually I have, which is why I know you can actually learn something from exploration.

Unlike yourself.

Give it a try, you might actually learn something.

As you like, my dearest dear :)

What I mean is clear.

At first they said: No water, only frozen CO2
Then they said: there is water ice in addition to the frozen CO2.

I expect they will later on say: no frozen CO2; only there is frozen water and liquid water.

Expectations based on what? Who is they, and where can we read what they said?

Who said about the sand storm on Mars?

I did... It's another reason for the temperature differences between the hemispheres.

So there are satllite images which aren't enough to differentiate between dry ice and water ice.

Satellites carry spectrometers.

It seems religion appeals to the simple-minded , looking for simplistic answers to explain the extremely complex universe.
Everyone needs to believe in something, because the idea that it's all meaningless is all to terrifying for some.

You get a thumbs up for actually posting something true.

To say I'm surprised by this, would be a monumental understatement.

On the observations about Mars, and on the interpretation of the Quran and deduction.

Who is they?

Astronomers.

No, the sandstorms are caused by the hot temperature; and it is related to the deserts included in the North hemisphere.

Satellites carry spectrometers.

The spectrometer will not say the CO2 is in the atmosphere or on the ground level as the alleged frozen CO2.

When I was in Grade 7 I learned that the warmth of a body is depenedent on the heat a body receives, the heat of the source of the heat, the length of the exposure of that heat, the distance from the heat source and the angle of the recipient from the heat source.

Simple: The Warmer the heat source the more heat I receive. I learned that the closer I sat to the stove, the warmer I got. The longer I sat close to the stove, the warmer I got. The more surface I presented towards the stove the warmer I got.

The Earth presents its Northern face to the Sun (due to tilted axis) at the time it is closer to the Sun. You know, almost 24 hour daylight in Alaska from March to September. At the same time it is dark and cold in the Southern Hemisphere.

At the other half of the year, when the Southern Hemisphere receives its heat from the Sun, it is farthest away.

Just as it was designed by Allah. Right????

The sandstorms move dust around, and it's not equal. It alters the albedo. Look it up.

Try again. This makes no sense.

Or try reading something like this:

Why is the south pole of Earth colder and with more ice than the north pole?
and the same situation on Mars also? :faroah:
Have not read the scientific repllies etc - But it is simple - the North Pole is closer to the sun.

You forgot the rate of emissivity. If you wrap yourself in a blanket, you emit (radiate) less heat away from your body, and you warm up.

South Pole is a huge land mass whereas North Pole is in the middle of an ocean and water has a moderating effect. :smile:

Certainly, sandstorms alters the albedo, and cause local lowering in the temperature in that region.



Such results are not absolute due to the far distance and limited access to reach exact results.

But eventhough see in the link that you give, what they say:

"The volume fraction of water is generally higher than can be accommodated in the pore space of surface soils, which implies that water vapor diffusion processes alone cannot explain the observations. Alternatives for the formation of the water-rich layer are discussed.

Results of our analysis of the residual-cap CO2 inventory support conclusions that the atmosphere is not buffered by a larger reservoir of surface CO2 at the poles and that Mars' total CO2 inventory is well represented by the present atmospheric mass."

This indicates that there is a water-rich layer which may be liquid surface water.

The CO2 in the atmosphere is not related to any alleged frozen CO2 in the poles, which may inidcate there is no such CO2 cap and that this cap may be only water ice.

This also is a factor.

Science doesn't deal in absolutes, that is left to ancient texts written by ignorant folk. Every measurement has uncertainty.

No, what it indicates is that there is substantial water below the Martian surface which cannot at present be explained, and that the carbon dioxide ice which forms at the poles is transient. The frozen carbon dioxide in the poles is seasonal.

If the shoe fits... though I don't think it does in your case, you're more thoughtful than that. But it's not always obvious, you're so bloody prickly about any challenge to or criticism of religion it's easy to think you're something you're not.

Sandstorms usually lower the temperature in that region; this is known here practically: after the sandstorm the weather will be colder.
The sand absorbs the heat from the atmosphere.

This is opposite to the rain: following the rain, or immediately at the start of the rain, it will be warmer. That is because the vapor converts into liquid water releasing considerable amount of heat.

Science doesn't deal in absolutes, that is left to ancient texts written by ignorant folk. Every measurement has uncertainty.

Here you are terribly wrong. And you mean the Quran; no it is the word of God as is the original Torah and Gospel; the ignorant are those that deny God's word and believe in changable theories.

No, what it indicates is that there is substantial water below the Martian surface which cannot at present be explained,

and that the carbon dioxide ice which forms at the poles is transient. The frozen carbon dioxide in the poles is seasonal.

As I said: it indicates a considrable amount of water on Mars which all of you had denied before, when we wrote our posts about life on Mars.

Refer to their wrangling and denial of this on the first threads here about life on Mars and that Mars is inhabited by people.

Moreover, it is only now that they say: the frozen CO2 is transient and seasonal (while they insisted before that the ice of the poles and mountain tops on Mars is of frozen CO2 --- refere to my thread about life on Mars and the poeple of Mars); and I tell you: not at all: the ice in the poles of Mars are water ice just like the condition is on Earth.

Meeting with the people of Mars.
It is very nice to go over their replies; see the reply of #Juan and what he said that 99% of polar ice is of frozen CO2 and enjoy reading their other replies and some of their mockery.

When an all inclusive statement is made putting down billions of people because of their faith, you can be damn sure I will not let it pass. Whether it be about Christianity, Islam, Judaism, or whatever.
