Answer:
The atmosphere: is mostly made of nitrogen, protects the Earth from harmful radiation, and contains water vapor.
Explanation:
The atmosphere can be defined as the gassy wrapping covering a planet, in this case, the Earth.
The Earth´s atmosphere is composed of water vapor, <u>N₂ (78.08%</u>), O₂ (20.95%), Ar (0.93%), CO₂ (~0.03%), and Oz (0.01%). There are also other gases in reduced concentrations. <u>Water vapor </u>might reach 4% of the atmosphere near the Earth's surface. Water vapor and ozone absorb infrared radiation and are important in defining the terrestrial clime and keeping the environmental conditions needed for life. <u>They protect the Earth from harmful radiation. </u>
The atmosphere is composed of different layers: troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The troposphere is the most inferior layer, in contact with the Earth´s surface, composing almost 90% of the atmospheric mass.
