1. • Nitrogen, oxygen, and argon

     • The three major constituents of Earth's atmosphere are nitrogen, oxygen, and argon. Water vapor accounts for roughly 0.25% of the atmosphere by mass.

   What particles are found in the atmosphere?

   • There are also many, tiny, solid or liquid particles, called aerosols, in the atmosphere. Aerosols can be made of dust, spores and pollen, salt from sea spray, volcanic ash, smoke, and pollutants introduced through human activity. The atmosphere becomes thinner (less dense and lower in air pressure) the further it extends from the Earth's surface.

   What atoms are in the atmosphere?

   • The remaining less than 1% of the atmosphere is a mixture of gases, including argon (Ar) and carbon dioxide (CO 2). The atmosphere also contains varying amounts of water vapor, on average about 1%. There are also many, tiny, solid or liquid particles, called aerosols, in the atmosphere.

   What are the layers of Earth's atmosphere?

   • Diagram of the layers within Earth’s atmosphere. Earth’s atmosphere has five major and several secondary layers. From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere. Troposphere.

   What does the atmosphere look like?

   • Let us know. Introduction to the Atmosphere The atmosphere is a layer of gas and suspended solids extending from the Earth's surface up many thousands of miles, becoming increasingly thinner with distance but always held by the Earth's gravitational pull.

   What is the Earth's atmosphere like?

   • That is essentially what the Earth’s atmosphere is like: layers upon layers of gas surrounding the Earth, working to protect the planet. We asked Rei Ueyama, an atmospheric scientist at NASA Ames Research Center, to explain a little bit more about the function and importance of our atmosphere.

   What gases are in the thermosphere?

   • The few gas molecules that are in the thermosphere are mostly oxygen, nitrogen and helium. Auroras happen when particles from the Sun interact with gases in our atmosphere, causing beautiful displays of light in the sky. Depending on where you are on Earth, these are sometimes also called northern lights or southern lights.

   Even when the air seems to be completely clear, it is full of atmospheric particles - invisible solid and semisolid bits of matter, including dust, smoke, pollen, spores, bacteria and viruses. Some atmospheric particles are so large that you will feel them if they strike you.

   The atmosphere of Earth is composed of a layer of gas mixture that surrounds the Earth's planetary surface (both lands and oceans), known collectively as air, with variable quantities of suspended aerosols and particulates (which create weather features such as clouds and hazes), all retained by Earth's gravity.
