How important is the atmosphere to life on earth?

Without the atmosphere, there would be no life on earth.


Why was life impossible in early earth?

Early Earth lacked oxygen in its atmosphere, had extreme temperatures, and high levels of radiation from the sun. Volcanic activity was also rampant, releasing toxic gases into the atmosphere. These harsh conditions made it difficult for life to thrive on early Earth.


What are the 3 sub-levels of the Biosphere?

The three sub-levels of the Biosphere are the lithosphere (land), hydrosphere (water), and atmosphere (air). These sub-levels interact and support life on Earth by providing habitats for different organisms.


How earth early atmosphere is differed from earth atmosphere today?

Earth's early atmosphere was primarily composed of gases like carbon dioxide, water vapor, and nitrogen released from volcanic activity, lacking significant levels of oxygen. Over time, the emergence of photosynthetic organisms led to an increase in oxygen levels, shaping Earth's current atmosphere with about 21% oxygen and a balance of nitrogen, argon, and other gases. This shift enabled the evolution of complex life forms.


Why does earth give life?

yes earth can give life because it has atmosphere


How was earth atmosphere changed since it was formed?

The Earth's early atmosphere was primarily composed of gases emitted from volcanic activity, such as water vapor, carbon dioxide, and nitrogen. Over time, the atmosphere underwent significant changes due to processes like photosynthesis by early life forms, which reduced carbon dioxide levels and increased oxygen levels. This shift allowed for the evolution of more complex life forms.


Which gas became part of earth's atmosphere mainly as a result of the evolution of life-forms?

Oxygen became a significant part of Earth's atmosphere due to the evolution of photosynthetic life forms, such as cyanobacteria and plants. These organisms produce oxygen as a byproduct of their metabolic processes, leading to the rise of oxygen levels in the atmosphere over time.


Which nonmetals are in the atmosphere and their combinations are essential for life on earth?

nitrogen, oxygen, and water are nonmetals in the atmosphere, and their cobinations are essential for life on earth


How does the atmosphere help provides the conditions necessary for life to exist on earth?

The atmosphere contains gases like oxygen and carbon dioxide that are essential for life. It also regulates temperature by trapping heat and protecting Earth from harmful radiation. Additionally, the atmosphere creates weather patterns that distribute water and nutrients essential for life.


What layer of the atmosphere are weather and life found?

Only the Troposphere has high levels (only 20% however) to suport life, but water vaper is found in all levels of the Atmosphere. But, when Evaperation mixes the water vaper found close to earth with the water in the Troposphere, it condesnes into a cloud before the vaper could have reached the outer layers.


What happens to greenhouse gases at natural levels in the atmosphere?

At natural levels of greenhouse gases in the atmosphere (before the Industrial Revolution), the carbon cycle moved carbon dioxide in and out of land, sea and air. Enough carbon dioxide remained in the atmosphere to keep the earth comfortably warm, warm enough for life.
