Explanation:
What is the composition of each layer of the atmosphere?
Oxygen — 21 percent.
Argon — 0.93 percent.
Carbon dioxide — 0.04 percent.
Trace amounts of neon, helium, methane, krypton and hydrogen, as well as water vapor.
The atmosphere is composed of a mix of several different gases in differing amounts. ... Nitrogen accounts for 78% of the atmosphere, oxygen 21% and argon 0.9%. Gases like carbon dioxide, nitrous oxides, methane, and ozone are trace gases that account for about a tenth of one percent of the atmosphere.
Earth's atmosphere is divided into five main layers:
the exosphere, the thermosphere, the mesosphere, the stratosphere and the troposphere. ... Ozone is abundant here and it heats the atmosphere while also absorbing harmful radiation from the sun.
What is atmosphere and its importance?
The Earth's atmosphere protects and sustains the planet's inhabitants by providing warmth and absorbing harmful solar rays. In addition to containing the oxygen and carbon dioxide, which living things need to survive, the atmosphere traps the sun's energy and wards off many of the dangers of space.
Answer:
Atmosphere, composition and structure. Earth's atmosphere is composed of about 78% nitrogen, 21% oxygen, and 0.93% argon. ... All of these trace gases have important effects on Earth's climate. The atmosphere can be divided into vertical layers determined by the way temperature changes with altitude.
