because it keeps the air inside the earth
Oxygen is the most essential element in Earth's atmosphere for human life. It is needed for cellular respiration, the process by which our cells generate energy. Without oxygen, humans would not be able to survive.
Biosphere.
The Earth's atmosphere contains oxygen, which is essential for respiration in most living organisms. It also contains carbon dioxide, which plants use for photosynthesis to produce food. Water vapor in the atmosphere is essential for the water cycle, which is vital for all forms of life on Earth.
The gas needed to establish before the Earth's atmosphere could absorb and maintain heat was carbon dioxide. This gas, along with other greenhouse gases like methane and water vapor, trap heat in the atmosphere and help regulate the Earth's temperature.
The layer of Earth's atmosphere vital to life is the troposphere. It is the lowest layer where weather occurs and contains the oxygen needed for humans and animals to breathe.
Bc its cool

it bounce back the UV radiations
Biosphere.
Atmospheres have many different purposes, however the Earths atmosphere is vital to its existense as it prevents the suns harmful radiation from reaching the Earths surface. Moreover, from an enviromental standpoint the errosion by pollutants will eventually destroy the delicate atmosphere and the Earths protective barrier will be gone.
Green plants evolved adding oxygen to the atmosphere.
more oxygen was consumed
Without life because when plants do photosynthesis, they produce oxygen.
it made it possible 4 it to be plants animals and human life
how do geologists think earths atmosphere is formed
STRATOSPHERE
Thermosphere, it is also the atmosphere with the highest temperatures.
