Question

What benefits does our atmosphere provide to earth?

Answer 1

Hint: Without the protective layer of gases that structure Earth's atmosphere, the tough conditions of the system would render the earth a barren, lifeless husk just like the moon. Earth’s atmosphere protects and sustains the organisms living on the planet by providing warmth and absorbing harmful solar rays. Additionally, to contain the oxygen and \[C{O_2}\], which living things have to survive, the atmosphere traps the sun's energy and wards off many of the risks of space.

Complete answer:
The atmosphere is a combination of gases that surround the planet earth. It's composed of roughly \[78\] percent nitrogen, \[21\] percent oxygen and one-hundredth other gases (water vapor and carbon dioxide). The earth’s atmosphere is important to the protection and survival of the earth and its living organisms.
On Earth, however, molecules within the atmosphere absorb the sun’s energy as it arrives, spreading that warmth across the earth. The molecules also trap reflected energy from the surface, preventing the night side of the earth from becoming too cold
The sun bombards the system with ultraviolet, and without protection, that radiation can cause severe damage to skin and eyes. The ozone layer high within the Earth’s atmosphere blocks much of this radiation from reaching the surface. The Dense layers of molecular gases which are present in the atmosphere also absorb cosmic rays, gamma rays and x-rays, preventing these energetic particles from striking living things and causing mutations and other genetic damage.
According to NASA, quite \[100\] plenty of space debris strikes Earth every single day,
When they encounter the molecules that structure Earth’s atmosphere. However, the resulting friction destroys them long before they reach the bottom.
Earth’s atmosphere is assumed to hold around \[12,900\] cubic kilometers (\[3,100\] cubic miles) worth of water at any given time. Without an environment, It might simply boil away into space, or remain frozen in pockets below the surface of the earth.
The ozone layer present in the atmosphere is a section of the earth’s atmosphere that acts as a barrier between the Earth and UV radiation. This ozone layer protects our earth from an excessive amount of radiation by both absorbing and reflecting harmful UV rays.
The atmosphere protects our earth from the vacuum present in space. The gasses and pressure that is present in the atmosphere allow living organisms to breathe. Atmosphere also prevents water from evaporating into space, without the atmosphere, there would be no life on the earth.

Note:
On a moon that has no protective atmosphere, temperatures can range from \[121\] degrees Celsius in the sun (\[250\] degrees Fahrenheit) to negative \[157\] degrees Celsius within the shade (negative \[250\] degrees Fahrenheit). On Earth, however, molecules within the atmosphere absorb the sun’s energy as it arrives, spreading that warmth across the earth. The molecules also trap reflected energy from the surface, preventing the night side of the earth from becoming too cold.
