The atmosphere's composition is caused BY life. When the Earth was formed the atmosphere was Nitrogen, CO2, and Methane and water vapour. Life has removed much of the methane and CO2 and added Oxygen. Therefore life and the atmosphere (and the rocks of the planet) are one big unified system with lots of biological cycles happening with them.
When O2 was added to the atmosphere this formed O3 (Ozone) in the upper atmosphere and this then blocked out most of the Sun's harmful (to life) ultraviolet radiation. When this happened it was possible for life to start colonising the Earth's land areas.
The atmosphere also blocks out most of the harmful cosmic radiation that impinges on the planet.
What else can I help you with?
What is the earths atmosphere's purpose?
to protect us from the sun's harmful rays
How does the the earths atmosphere support life?
Bc its cool
How do greeenhouse gases protect earths atmosphere?
They dont they just make the earth hotter
Why does earths atmosphere absorb radiation?
It absorbs radiation to protect it. It protects from UV rays.
Why does the atmosphere help sustain and protect life on the earths surface?
The atmosphere helps sustain and protect life on Earth's surface by trapping heat from the sun, moderating temperature extremes, and blocking harmful radiation such as UV rays. It also helps regulate the water cycle by holding water vapor and enabling precipitation, supporting diverse ecosystems and life forms.
Why is earths atmosphere good for life?
it bounce back the UV radiations
Earths water land and atmosphere where life exists is known as?
Biosphere.
What are rockets made off?
steel, with durible titanuim palting to protect it from breaking up in earths atmosphere
Why does the atmosphere have layers?
The atmosphere has layers due to variations in temperature and composition at different altitudes. These layers help to protect the Earth by trapping heat, blocking harmful solar radiation, and supporting weather patterns. The main layers of the atmosphere are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
What is main cause of earths atmosphere changing over time to support life?
Green plants evolved adding oxygen to the atmosphere.
Why does earths position in the milky way galaxy help protect life?
why does earhs position in the milky way galaxy help protect life
As life began to populate earths surface what change was seen in the atmosphere?
more oxygen was consumed
