When will the air be full of carbon dioxide such that humans would not take in enough oxygen?
The air contains around 0.04% CO2. Plants absorb carbon dioxide, ehich they use in photosynthesis. Without the plants, there would be no life on earth. Algae also absorb CO2 to make their food. Without both the plants abd the algae, both the atmosphere and hydrosphere (seas and oceans) would be anoxic.
Why was there so much carbon dioxide in the early earth?
In the early Earth, volcanic activity was rampant, releasing significant amounts of carbon dioxide (CO2) into the atmosphere. Additionally, the lack of plant life meant that there were no processes like photosynthesis to absorb CO2. The early atmosphere was also influenced by the outgassing of gases from the Earth's interior, contributing to high CO2 levels. Over time, as life evolved and photosynthetic organisms emerged, the balance of gases in the atmosphere began to change.
Is CO2 a good gas or bad gas?
CO2 is a natural component of the Earth's atmosphere and is essential for plant growth through photosynthesis. However, an excess of CO2 due to human activities like burning fossil fuels is a major contributor to climate change and global warming. So, while CO2 itself is not inherently "good" or "bad," its overabundance due to human activities poses significant environmental challenges.
What would happen if no carbon dioxide was the air?
If there were no carbon dioxide (CO2) in the air, photosynthesis would cease, as plants rely on CO2 to produce oxygen and food. This would lead to a collapse of ecosystems dependent on plant life, severely diminishing the food supply for herbivores and, subsequently, carnivores. Additionally, the Earth's temperature would drop significantly, as CO2 plays a crucial role in trapping heat in the atmosphere. Overall, the absence of CO2 would disrupt the balance of life on Earth and could lead to a mass extinction event.
Which gas makes up 036 of earth's atmosphere?
Carbon dioxide (CO2) makes up approximately 0.04% of Earth's atmosphere.
If CO2 was not on earth what will earth be like?
If there was no Carbon Dioxide on Earth it would be very different then what it is now. Firstly plants need CO2 for photosynthesis, without CO2 plants could not complete photosynthesis and would die of starvation (photosynthesis is a plants way of making food). Secondly CO2 is a gas that keeps the Earth's temperature at the correct level, without CO2 the Earth would be much colder and therefor unable to support life.
How can earth have life on it but the other planets do not?
Because, Earth is at a right distance from the size of our sun which where water could exist and our atmoshpehere with many gases and not just CO2. Mars could sustain life but need to reduce the level of co2 in its atmosphere to sustain fresh, liquid water.
How earth is a living planet?
As earth supports life,we consider it as living planet,But there are many components on earth which supports life i.e water,atmosphere,temperarure......Its distance from sun provide it proper temperature that suits life....that temperature is such that liquid like water can exist & living beings can survive
Could life as you know it exist on earth if air only oxygen?
No....as you see for life not only oxygen is needed for instance we need food for that we have to depend on plants.here plants need CO2 to prepare food which they get from air....!!
Why are algae important?
No, they produce Co2 which is used for plants to breathe then the plants produce oxygen. This is wrong. Green algae produce 70 to 80% of the oxygen on earth. We would not exist without them.
Why is CO2 essential to all life on earth?
Well, for humans CO2 is bad for is because it gets more humid in the atmosphere, but however the plants need the CO2 to process it into oxygen. Which we need.
Why is there a natural balance of the amount of carbon dioxide and the amount of oxygen around earth?
Without carbon dioxide and water vapor, we would be a cold dead planet. Oxygen is needed for the life cycle, as is CO2. When something dies, that co2 is returned to the atmosphere through burning or decay.
Why dry ice don't melt?
Dry ice is made of raw CO2. Liquid CO2 cannot exist under earth's atmosphere. For this reason, when dry ice sublimates, it turns from solid directly to gas.
Where will CO2 be found?
Natural carbon dioxide exist in mineral waters, in volcanoes gases, in the Earth crust. Carbon dioxide is released by animals during respiration.
What do you think earth atmosphere would be like today if life had not evolved one earth?
Almost no oxygen, lots of CO2, still mostly nitrogen.
Can CO2 exist in a solid state?
Yes, carbon dioxide (CO2) can exist in a solid state under certain conditions, such as at very low temperatures and high pressures. This solid form of CO2 is commonly known as dry ice.
CO2 makes up what percentage of atmosphere?
CO2 makes up approximately 0.03% of Earth's atmosphere
