Yes there is air on Mars. But it is 100 times thinner than air on Earth, and it is mostly carbon dioxide. There is no free oxygen in it. It would be poisonous to humans.

The term "air" is a catch all word for atmosphere. Earth's air is mostly nitrogen and oxygen, Martian air is mostly carbon dioxide. The surface on Mars is about 1% of the surface pressure on Earth. So air molecules move much quicker - there are far fewer molecules for them to run into. Therefore, the wind velocity on Mars is much higher than on Earth, in the range of 100s of miles per hour. Sandstorms on Mars may start small, but in a few hours can grow to a planetary scale and obscure much of the surface from view.

If you were to strip away all the oxygen, nitrogen and water out of earths atmosphere you would end up with martian "air". It´s almost all carbon dioxide and very thin compared to earths. So mars only have a faint shadow of an atmosphere and although you can´t really call it air (exposed to the martian atmosphere you would die within seconds) it is able to whisk up dust and cause huge dust storms.

Yes.
Mars has an atmosphere composed mostly of carbon dioxide (95%) with smaller amounts of nitrogen and argon. But the air is very thin: the surface pressure on Mars averages about 7 millibars, compared to 1013 millibars on Earth.

Yes, it has an atmosphere. All the rocky planets do to some extent. Mercury, Venus, Earth and Mars. Many of the moons also have an atmosphere.

Yes, it has "air", but not as we call it here. It is predominantly composed of carbon dioxide, and is therefore not breathable by many forms of life present on earth. If it were warmer and had liquid water then it would be possible for some forms of plant life or bacteria to live there.

winds of carbod dioxide and carbod monoxide. mars has an atmosphere. just no like the air on earth. there is no oxygen present

If you mean air that you can breathe,there are some that believe mars might have had at one time small amounts of oxygen,which now might be inbeded in rocks or ice

It has a gaseous atmosphere but they do not have plants to recycle the air. I think that a large part of it is CO2.

Yeah, Mars does have an atmosphere. That's why its sky is red during the day. You can't have a sky without an atmosphere.
