It's not accurate to say there's a single "force" of gases on Earth. The Earth's atmosphere is made up of gases that exert pressure on the Earth's surface and everything on it. This pressure is caused by the weight of the atmosphere above.

Here's a breakdown:

* Atmospheric pressure: The weight of the air above a certain point exerts a force on that point. This force is called atmospheric pressure.

* Gas pressure: Each gas in the atmosphere contributes to the overall pressure, and the pressure of each gas is proportional to its concentration.

* Forces from wind: Moving air (wind) creates forces on objects, but these forces are caused by the movement of the air itself, not the gases as a whole.

Here are some key points to remember:

* Pressure is not a force, but a force per unit area.

* The Earth's atmosphere is held in place by gravity.

* Atmospheric pressure varies depending on altitude. It's higher at sea level and lower at higher altitudes.
