Although both nitrogen and oxygen are essential to human life on the planet, they have little effect on weather and other atmospheric processes. The variable components, which make up far less than 1 percent of the atmosphere, have a much greater influence on both short-term weather and long-term climate. For example, variations in water vapor in the atmosphere are familiar to us as relative humidity. Water vapor, CO2, CH4, N2O, and SO2 all have an important property: they absorb heat emitted by the earth and thus warm the atmosphere, creating what we call the "greenhouse effect." Without these so-called greenhouse gases, the surface of the earth would be about 30 degrees Celsius cooler - too cold for life to exist as we know it. Though the greenhouse effect is sometimes portrayed as a bad thing, trace amounts of gases like CO2 warm our planet's atmosphere enough to sustain life.Global warming, on the other hand, is a separate process that can be caused by increased amounts of greenhouse gases in the atmosphere.
Earth's atmosphere is a mixture of gases that surrounds the planet and sustains life by providing oxygen for humans and other living organisms to breathe, regulating the temperature through greenhouse gases that trap heat, protecting from harmful solar radiation, and facilitating the water cycle through processes like evaporation and condensation.

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 does the earths atmosphere help sustain and protect life?
The Earth's atmosphere provides essential elements such as oxygen for respiration, absorbs harmful radiation from the sun, regulates temperature through the greenhouse effect, and shields the planet from harmful space debris. These factors collectively create a habitable environment that sustains and protects life on Earth.
What term describes the part of the atmosphere that can sustain life?
The term is "biosphere." It refers to the zone within the Earth's atmosphere, hydrosphere, and lithosphere where life exists.
Earths water land and atmosphere where life exists is known as?
Biosphere.
How does the atmosphere make earths temperatures suitable for life?
The atmosphere's composition allows it to trap heat from the sun through the greenhouse effect, which helps regulate Earth's temperature. Gases like carbon dioxide and water vapor in the atmosphere absorb and reradiate heat, keeping the planet warm enough to support life. Without this natural greenhouse effect, Earth would be too cold to sustain life as we know it.

What do you need in atmosphere to sustain life?
oxygen and sunlight
What is the earths special feature?
It's ability to sustain life - despite the vast size of the universe, so far earth is the only planet with the ability to sustain life
Could mercury sustain life?
No, it doesn't even have a substantial atmosphere.
Which helps in maintaining the right temperature to sustain life on earth?
atmosphere
How does the the earths atmosphere support life?
Bc its cool
Why does the earths interior have to be studied indirectly?
the heat and pressure in the interior is not designed to sustain human life
Is the Earth's atmosphere important to us?
The Earths athmosphere is one of the most important things to us. The athmosphere is very delicate and contains all the protection we need from meteorites, UV rays, and allows the Earth to sustain life.
What is oxyghen?
An incorrect spelling of the word oxygen, which is an element found in many organic compounds. O2 is the chemical formula for oxygen found as a gas and is about 21% of the earths atmosphere, which is needed for aerobic respiration and therefore to sustain life.

Why is earths atmosphere good for life?
it bounce back the UV radiations
