The atmosphere becomes less dense with altitude. Atmosphere, thin though it is, has weight, and it is the weight of the air above which compresses the air below it, to greater density.
the particles get closer together because my class just talked about that stuff!!
With helium filled balloons, they rise upwards as the gas inside is of a lower density than the atmosphere around them. The balloon will continue to rise and the gas inside it will expand as the atmospheric pressure decreases with increasing altitude. Eventually, the gas inside the balloon will expand enough to burst the balloon and the balloon will fall back to the ground. When and where this happens depends on weather conditions, air temperature, the rubber used in the balloon, etc.
Increasing the air temperature inside the balloon will cause the air inside to become less dense and expand, making the balloon buoyant and rise. Conversely, decreasing the air temperature inside the balloon will cause the air to become denser and contract, making the balloon less buoyant and descend. By controlling the temperature inside the balloon, you can effectively control its altitude.
Because there is less air above, pushing down.

The atmosphere becomes less dense with altitude. Atmosphere, thin though it is, has weight, and it is the weight of the air above which compresses the air below it, to greater density.
As you travel higher in Earth's atmosphere, the composition of gases changes in terms of their concentration. Oxygen, nitrogen, and argon are the most abundant gases in the lower atmosphere, while the percentage of oxygen decreases and other gases like helium and hydrogen become more prevalent in the upper atmosphere. The overall pressure also decreases with altitude, causing the air to become less dense.
Isolation generally increases with altitude due to reduced temperature, lower air pressure, and limited access to resources. As altitude increases, the availability of oxygen decreases, temperatures become colder, and environmental conditions become harsher, thus increasing isolation.
As altitude increases, air pressure decreases. Gravity causes the atmosphere to become heavier the closer you are to the ground. The atmosphere may seem weightless but all the air molecules add up to a tremendous amount of mass. If you think of the atmosphere like blankets, the more blankets you have piled on you the heavier they become, thus pressing down on your body more and more. This is the same in the atmosphere, where the higher the altitude, the less overlying atmosphere, the less pressure on air molecules. At higher altitudes the air molecules have more freedom to move around.
Gas molecules in Earth's atmosphere are more concentrated near the surface and become less dense as altitude increases. The distribution is governed by gravity, with heavier gases concentrated at lower altitudes and lighter gases found at higher altitudes. This creates layers within the atmosphere, such as the troposphere (where most weather occurs) and the stratosphere (where the ozone layer is located).
no but you have to answer to your teacher. Edit : Yes, there is a small amount of ice in the Earth's atmosphere in the form of high altitude clouds. It's cold enough for water to become little ice crystals.
as the altitude increase, the effect of gravity become more insignificant on air and the air become more disperse or thinner hence it does affect the air pressure and density by decreasing both air pressure and density of the air.
your question is... How did the Earth`s atmosphere change composotion to became today`s nitrogen and oxygen atmosphere? Answer: it happend with the help of solar untraviolet (uv) radiation,the very thing what we worry about now for its cancer-causing ability
The atmosphere becomes less dense as altitude increases because there is less weight on the air molecules,making them less compressed. The air at a low altitude is denser because it is pressed down by all of the weight of all the air molecules above it.
The air pressure decreases with altitude because there is less atmosphere above pressing down. Therefore, the air molecules are more spread out, leading to lower density of gas molecules in the upper layers of the atmosphere.
because they reflect the suns light, so they become visible to us. they twinkle due to the earths atmosphere blocking out some of the light.
