What are the four spheres of the Earth in order?

The four spheres of the Earth in order are: Atmosphere (air) Hydrosphere (water) Lithosphere (land) Biosphere (living organisms)


How much water vapor is in the stratosphere?

According to the USGS and NOAA, a 1km³ cumulus cloud would weigh about 2.21 billion pounds, or about 1,105 tons (US). The same volume of dry air weighs about 2.22 billion pounds, which is why clouds float. Because it is less dense than air, in truth, it doesn't "weigh" anything. It has volume. If you sucked all the water vapor out of the air and put it in a bucket, though, using the below chart as a guide and the fact that water is 1kg per liter, and one liter of water is 0.1 cubic meters, you'd have 12,900,000,000 liters of water, which is 12.9 trillion kg. (It's enough to cover the earth's 510,072,000 km² surface with about 25mm of water. Because the earth's average rain fall is about 1 meter, you can figure that all of this water vapor is recycled every nine or ten days.) So, to convert that metric to US tons and answer your question, all of that means that there is approximately more than 14.2 billion US tons of water vapor in the atmosphere.

How much oxygen is in earth's atmosphere?

Oxygen makes up about 21% of Earth's atmosphere by volume. This concentration has remained relatively stable for millions of years due to the balance between oxygen production by photosynthesis and consumption through various chemical reactions.


How can one setup a visual comfort lighting atmosphere?

To create a visual comfort lighting atmosphere, consider using warm white or soft light bulbs with dimmable controls to adjust brightness. Opt for fixtures that distribute light evenly across the room and avoid harsh glare by positioning lights away from direct line of sight. Incorporating layers of lighting, such as overhead, task, and accent lighting, can also help to create a balanced and visually appealing atmosphere.


Water vapor that forms droplets and falls to the earth?

That is precipitation, specifically in the form of rain. When water vapor in the atmosphere cools and condenses into droplets that become heavy enough to fall as rain, this process is part of the water cycle.
