Mention of the classical elements

Is it necessary for this article to mention the four classical elments? Scientists think that the periodic table of the elements provides an accurate view of the natural elements. The periodic table can also be grouped into smaller tables, which could make understanding it easier.

Just my thoughts; what does everyone else think? Secretkeeper12 (talk) 00:59, 23 August 2014 (UTC)

Air is colorless and odorless?

Wouldn't being colorless limit the definition to only allow particles to a certain size? Isn't the blue color of the day sky a product of light being filtered by our atmosphere? Would smog or clouds not constitute air? Smog as well as morning dew and even many gases have odor. Is this not also part of air? Also, whatever air we have experienced most often, I would think, would set our baseline of odorless and we would experience odor in other conditions relative to our baseline. To my confusion air does not seem well defined.

Pollution

"Air can be polluted by some gases (such as ozone and carbon monoxide), smoke, and ash. This pollution is one of the reasons for global warming, by causing the "greenhouse effect"." Wrong - smoke, ashes, etc. do not cause global warming.

Misinfographic

The pie chart states 20% Oxygen while the text states 21% - the "Atmosphere of Earth" page on Wikipedia puts it as 20.95% - should the image be removed or can someone update it?

After also noting the Nitrogen portion was 79% instead of 78% I took the liberty of removing the pie chart from the article until it can be corrected.Norlesh (talk) 11:15, 3 May 2020 (UTC)
