- Without it, life as we know it wouldn’t exist. Not only does it contain the oxygen we need to live, but it also protects us from harmful ultraviolet solar radiation. It creates the pressure without which liquid water couldn’t exist on our planet’s surface. And it warms our planet and keeps temperatures habitable for our living Earth.

Apr 24, 2017 · The atmosphere protects the Earth from the vacuum. The gasses and pressure of the atmosphere allow living organisms to breathe. The atmosphere also prevents water from vaporizing into space. Without the atmosphere, there would be no life on the Earth.

Oct 2, 2019 · Earth's atmosphere is essential to life, yet the invisible gases that form our "security blanket" can be hard to grasp. A new five-part series looks at our atmosphere, human impacts on it and ways NASA is studying the changing air we breathe.
Jul 23, 2023 · Earth's atmosphere protects the planet in more ways than one. This thin band of air is unique to Earth, and we wouldn't exist without it.

The atmosphere is thin and light, a gas that is only bound to the solid mass of the Earth by gravity. The mass of the atmosphere is about 250 times less than that of the oceans and accounts for less than one millionth of the total mass of the planet. The atmospheric pressure and density of air decrease exponentially with height above the surface. T...
A Perfect Planetemphasises how different elements of our environment are interconnected. The atmosphere responds to varying heating by sunlight, driving movement. These motions in the troposphere are what we experience as wind. The oceans supply water vapour, which absorbs and releases heat, forms clouds and scatters sunlight. The patterns of conti...
A basic necessity for humans is to breathe oxygen at a sufficient pressure for our respiratory system to work. Complex, multicellular life on Earth needs an atmosphere for either respiration or photosynthesis. Even aquatic species rely on dissolved oxygen from the air. Photosynthesis, in contrast, requires carbon dioxide, also from the atmosphere. ...
One way that the atmosphere impacts us all is through ‘weather’. Weather is simply the day-to-day change in the atmosphere around us. The atmosphere changes rapidly because it has a relatively low density and, as a gas, it is able to flow freely. Change in the oceans or the rocky surface of the Earth happens over longer timescales. Weather affects ...
The atmosphere is vital for all life on the planet, not only humans, and for reasons other than supplying gases needed for respiration and photosynthesis. Winds also transport water into the interiors of large areas of land, which would otherwise rapidly become parched desert. This supply of fresh water is essential to life on Earth. An illustratio...
The atmosphere also shields life. Many small rocks are littered throughout the Solar System, left over from the violent processes that occurred during its formation or formed in subsequent collisions between objects. Small rocks, called meteoroids, frequently encounter the Earth. Most burn up when they enter the atmosphere and do not reach the grou...
The Earth also emits electromagnetic waves, but at its cooler temperature these are at a longer wavelength of around 10 mm, known as the thermal infrared region. The atmosphere is not completely transparent to thermal infrared radiation, and several gases (including methane, nitrous oxide, water vapour and carbon dioxide) absorb energy in the wavel...
It is interesting to compare temperatures on the Earth and the Moon’s surface. The Moon is, on average, the same distance from the Sun and is made of dark rock. In the day, the surface temperature can reach 130 °C and then fall to -175 °C at night. This huge cycle of over 300 °C is far greater than is seen anywhere on Earth, and it might appear sur...
This article has discussed why the atmosphere is beneficial for life, but weather can also be deadly. Even apparently destructive aspects may have benefits to life on the planet as a whole; life evolves under the stresses of a changing environment. The ‘Great Oxygenation Event’ of the atmosphere led to the development of respiration, employed by an...
May 13, 2024 · Although we cannot directly see the atmosphere, it provides the air we breathe and protects us from harmful ultraviolet (UV) rays. The atmosphere also works to trap heat and maintain moderate, habitable temperature ranges.
The atmosphere protects life on earth by shielding it from incoming ultraviolet (UV) radiation, keeping the planet warm through insulation, and preventing extremes between day and night temperatures. The sun heats layers of the atmosphere causing it to convect driving air movement and weather patterns around the world.
