Yes. The atmosphere is a vital source of oxygen, water vapor, and carbon dioxide, all of which are necessary components of life. While it is technically not a source of these, it is a very important sink in which these gases are temporarily stored and cycled.
Correct. Earth's atmosphere was necessary for the development of life and is essential for its continued existence.
Without the biosphere, Earth would likely resemble a barren, lifeless planet with no greenery, animals, or bacteria. Without the atmosphere, Earth would be exposed to harmful solar radiation and extreme temperature fluctuations, making it uninhabitable for most life forms.
Cold and lifeless.
Without an atmosphere, Earth would be much colder as there would be no greenhouse effect to trap heat. There would be no protection from harmful cosmic rays and meteoroids, making life as we know it impossible. The lack of atmosphere would also result in extreme temperature differences between day and night.
If there was no atmosphere, there would be no air for us to breathe, leading to suffocation and the inability for life to exist on Earth. Additionally, the lack of atmosphere would result in extreme temperature fluctuations between day and night, and increased exposure to harmful solar radiation.
Cold. Lifeless. A wandering planet. Who knows what would happen to such an 'orphan'.
The moon is dusty and lifeless because it lacks a thick atmosphere to protect it from space debris - resulting in constant bombardment that grinds rocks into fine dust. Additionally, the moon lacks liquid water and a magnetic field necessary to support life as we know it.
Without the atmosphere, there would be no life on earth.
Otherwise all incoming radiation would be trapped and re-radiated in the upper atmosphere. A comparatively small amount would ever make it down to the surface, so the world would probably be cold and mostly lifeless.
Earth rotates because if i did not we would not have any atmosphere and we need an atmosphere to live.
If the earth had no atmosphere then there would be no life on earth and you would not be there to ask this question!
During a lunar eclipse with no atmosphere on Earth, the moon would appear dark and reddish due to the sunlight refracted by the Earth's atmosphere. Without the atmosphere, the moon would not have the red hue and would instead appear darker and possibly slightly illuminated by sunlight passing through the Earth's shadow.
