What else can I help you with?
Makes up 21 percent of the atmosphere?
Oxygen makes up 21% of the Earths atmosphere.
How important is the atmosphere to life?
The atmosphere is crucial for life on Earth as it provides essential gases like oxygen for respiration and carbon dioxide for photosynthesis. It also protects living organisms from harmful solar radiation and helps regulate temperature through the greenhouse effect. Additionally, the atmosphere plays a key role in weather and climate, which are vital for ecosystems and agriculture. Without a stable atmosphere, life as we know it would not be sustainable.
What is the percentage of nitrogen in the atmosphere?
Nitrogen makes up about 80% of the Earth's atmosphere.
Explain the relationship between plants and an atmosphere suitable for sustaining life?
Plants play a crucial role in creating an atmosphere suitable for sustaining life by producing oxygen through photosynthesis. Oxygen is necessary for the respiration of many living organisms, including humans. Additionally, plants help regulate levels of carbon dioxide in the atmosphere, which is important for maintaining a stable climate. Without plants, the atmosphere would lack the necessary oxygen levels to support life as we know it.
What is the gas that makes up the largest percent of the atmosphere?
Nitrogen makes up 78% of the Earth's atmosphere. Oxygen makes up about 21%.
What are the conditions for life?
atmosphere water gasses stable temperature
How much of the air oxygen?
Oxygen makes up about 21% of Earth's atmosphere. This level has remained relatively stable over long periods of time, supporting life on our planet.
What makes a planet living Explain using mars and earth?
A planet is considered "living" when it has the necessary conditions to support life, such as liquid water, a stable atmosphere, and suitable temperatures. Earth exemplifies this with its abundant water, diverse ecosystems, and protective atmosphere, fostering a rich variety of life forms. In contrast, Mars, while having signs of past water and some seasonal changes, currently lacks a stable atmosphere and has extreme temperatures, making it inhospitable for life as we know it. Thus, the presence of essential resources and stable environmental conditions are key to determining a planet's ability to support life.
What gas in your atmosphere makes life possible?
oxygen
What makes a world habitable?
A world is habitable if it has a stable climate, availability of water, a breathable atmosphere, and sufficient resources to support life. Factors like distance from its star, presence of a protective atmosphere, and geological stability also contribute to a world's habitability.
What does our atmosphere do that makes conditions on Earth suitable for life?
You have it wrong way round, the atmosphere of Earth was created by the life on Earth. 4000 million years ago the atmosphere had no oxygen and was full of CO2, Nitrogen and Methane. However life came into existence in this atmosphere and over time has altered the atmosphere to what we have today. Therefore the composition of the atmosphere would not appear to be critical to life.
What contribution does each layer of the atmosphere make in sustaining life on Earth?
Atmosphere makes huge efforts. It is the one because of which life sustains.
Does the atmosphere keep the earths temperature stable?
Yes, the atmosphere helps regulate Earth's temperature by trapping heat from the sun through the greenhouse effect. This helps maintain a relatively stable climate suitable for life on Earth.
Is xenon rare radioactive or stable?
Xenon is a stable noble gas that is not radioactive. It is not rare in the Earth's atmosphere, but it is considered a trace element because it makes up a very small proportion of the air we breathe.
Is oxygen stable or radioactive?
Oxygen, under normal conditions, is non-radioactive. But there are traces of radioactive isotopes present which makes the oxygen slightly radioactive. Additionally, these isotopes have long half-lives, so the radiation given off will not be a lot within a period of time.
Makes up 21 percent of the atmosphere?
Oxygen makes up 21% of the Earths atmosphere.
What makes the earth able to sustain life?
The Earth can sustain life due to its ideal distance from the sun, presence of liquid water, protective atmosphere, and stable climate. These factors create conditions that support the existence of diverse forms of life on our planet.
