Air presents in layers within the atmosphere, primarily due to variations in temperature, pressure, and density at different altitudes. As altitude increases, temperature generally decreases in the troposphere, leading to changes in air density and pressure. This stratification occurs because warmer air is less dense and rises, while cooler, denser air sinks, creating distinct layers. These variations impact weather patterns, climate, and the behavior of aircraft.
What else can I help you with?
What term specifically describes the process wherein the sun's radiation becomes trapped in the earth's atmosphere?
greenhouse effect Visible light come in, is absorbed by the earth's surface and reemitted as IR, the IR cannot escape the atmosphere to space so heat builds up in the atmosphere.
What characteristic of the atmosphere stays the same?
The composition of the atmosphere remains constant at different altitudes, with nitrogen making up about 78% and oxygen about 21%.
What is the order of colors absorbed by the atmosphere at different altitudes?
As light passes through the atmosphere, shorter wavelengths such as blue and violet are absorbed more effectively, especially at higher altitudes. This results in the scattering of blue light, making the sky appear blue. As altitude increases, there is less atmospheric interference, leading to the absorption of longer wavelengths like red and orange at lower altitudes. Thus, the order of colors absorbed tends to be violet and blue at the highest altitudes, followed by green, yellow, and finally red at lower altitudes.
How does CO2 get into the upper atmosphere?
CO2 in the atmosphere exists throughout different layers, but it is mainly transported to the upper atmosphere through atmospheric circulation and mixing processes. Some CO2 molecules can also be carried to the upper atmosphere by volcanic eruptions or in the form of methane, which can be oxidized into CO2 at higher altitudes.
What is gravity of the atmosphere?
The force of attraction between the Earth and all other particles of matter in its atmosphere. The acceleration of gravity on Earth is 9.81m/s^2. This means that, no matter what the weight of the object is, it accelerates towards the Earth at 9.81 m each second and the Earth 9.81 m towards it.
What is a sentence for the word altitudes?
Cloud structures vary at different altitudes due to different levels of air pressure. There are several scientifically recognized altitudes of atmosphere.
Is it colder at higher altitudes compared to lower altitudes?
Yes, it is generally colder at higher altitudes compared to lower altitudes due to the decrease in air pressure and the thinner atmosphere, which results in less heat being retained.
What characteristic of the atmosphere changes with altitude?
The temperature and level of oxygen. High altitudes sometimes have more snow and low altitudes are usually drier.
Layered gases thin air little moisture are?
This could describe the atmosphere at high altitudes, such as on a mountaintop. At higher altitudes, the air is thinner, meaning that there is less pressure and fewer gas molecules present. Additionally, the air at these altitudes tends to have lower humidity levels, resulting in less moisture in the atmosphere.
What term specifically describes the process wherein the sun's radiation becomes trapped in the earth's atmosphere?
greenhouse effect Visible light come in, is absorbed by the earth's surface and reemitted as IR, the IR cannot escape the atmosphere to space so heat builds up in the atmosphere.
What does large temperature gradient at high altitudes of the atmosphere cause?
Polar jet streams
What is neptunes atmospehere like?
At high altitudes, Neptune's atmosphere is 80% hydrogen and 19% helium.
Do you sunburn faster at higher altitudes?
Yes, you can sunburn faster at higher altitudes because the atmosphere is thinner, allowing more of the sun's harmful UV rays to reach your skin.
Is pressure uniform throughout the atmosphere?
No, pressure is not uniform throughout the atmosphere. Pressure decreases with increasing altitude due to the weight of the air above pushing down on the air below. This results in higher pressure at lower altitudes and lower pressure at higher altitudes.
What characteristic of the atmosphere stays the same?
The composition of the atmosphere remains constant at different altitudes, with nitrogen making up about 78% and oxygen about 21%.

Thus, the order of colors absorbed tends to be violet and blue at the highest altitudes, followed by green, yellow, and finally red at lower altitudes.
What is the atmosphere layer in which gases do not maintain a uniform composition?
The layer of the atmosphere where gases do not maintain a uniform composition is the heterosphere. In the heterosphere, gases tend to separate into layers based on their molecular weights, with lighter gases being found at higher altitudes and heavier gases at lower altitudes.
