what is the differnce in primary atmospheric gases at 1800 ft?

To determine the difference in primary atmospheric gases at 1800 ft, we need to understand the composition of Earth's atmosphere and how it varies with altitude. The Earth's atmosphere is primarily composed of several gases, including nitrogen (N2), oxygen (O2), argon (Ar), carbon dioxide (CO2), and trace amounts of other gases.

Typically, the concentration of these gases in the atmosphere decreases as we increase in altitude. Generally, the most abundant gases are nitrogen and oxygen. At sea level, nitrogen makes up about 78% of the atmosphere, while oxygen comprises approximately 21%. The remaining 1% includes argon, carbon dioxide, and trace gases.

As we ascend in altitude, the density of the air decreases, thereby affecting the composition of gases. However, it's important to note that the concentration of the primary atmospheric gases will vary based on several environmental factors and location.

To precisely determine the difference in primary atmospheric gases at 1800 ft, it would be best to refer to atmospheric data for the specific location and time you are interested in. There are multiple sources available to access atmospheric data, such as meteorological organizations, climate research institutions, and government agencies. These sources will provide comprehensive information on the composition of gases at different altitudes, including 1800 ft above sea level.
