the concentration and of carbon dioxide and oxygen remains constant in the atmosphere because when human throw carbon dioxide out of their body so plants take it and when plants throw oxygen so human take it.

Why are atmospheric carbon dioxide levels increasing while total carbon levels remain constant?

Atmospheric carbon dioxide levels are increasing because human activities, such as burning fossil fuels, release more carbon dioxide into the atmosphere than natural processes can remove. This imbalance leads to a buildup of carbon dioxide in the atmosphere, even though the total amount of carbon on Earth remains relatively constant.


Is the ratio nitrogen to oxygen changed by altitude?

Yes, the ratio of nitrogen to oxygen in the atmosphere remains constant regardless of altitude. Both nitrogen and oxygen are main components of Earth's atmosphere, with nitrogen making up about 78% and oxygen about 21%. Other gases, such as trace gases like argon and carbon dioxide, make up the remaining 1%.


What name is given to the process by which detritivores return carbon to the atmosphere?

Decomposition. Detritivores are decaying organic creatures, their faecal matter, or both. The carbon in their remains decomposes into the atmosphere.


What is the difference between homosphere and the heterosphere?

In the homosphere the concentration of gases remains the same throughout, and the gases are mixed, always in the same proportions. In the heterosphere the concentration of gases is different in different places, and the gases are typically in the form of layers, rather than mixed together.


Why does the atmosphere's composition remain stable?

The Earth's atmosphere is stable because is mostly oxygen and nitrogen. These two parts of the atmosphere are equal to about 99% of all dry air gas. Water vapor accounts for negligible amounts. While the composition of water vapor, carbon dioxide and ozone can vary in concentration, all other elements remain stable.

Why is it assumed that the amount of c-14 in the atmosphere remains constant?

It is assumed that the amount of C-14 in the atmosphere remains constant because the production of C-14 by cosmic rays and its decay into nitrogen-14 are in equilibrium. This equilibrium has been established over thousands of years, leading to a relatively stable concentration of C-14 in the atmosphere.


Is the level of carbon dioxide changed by altitude?

Carbon dioxide is heavier than nitrogen (N2) or oxygen (O2), the primary constituents of our atmosphere (75% and 20%, approximately). But wind does a fairly thorough job of mixing the CO2 in the lower atmosphere, lofting it into the upper atmosphere. As an aside, CO2 will collect in cave depressions, such that people venturing into caves or old mine cavities are subject to asphyxiation.


What is the percentage of nitrogen in the homosphere?

Nitrogen makes up about 78% of the Earth's atmosphere in the homosphere (the lower atmosphere where gases are well-mixed). This high concentration remains fairly constant throughout the homosphere.

Why the proportion of nitrogen in air remains constant?

The proportion of nitrogen in air remains constant because nitrogen is a chemically stable and non-reactive gas. It does not participate in chemical reactions in the atmosphere, so its concentration remains consistent over time. Additionally, the balance of nitrogen in the atmosphere is maintained by processes such as nitrogen-fixing bacteria in the soil and lightning, which help replenish nitrogen levels.


What stays constant at equilibrium?

At equilibrium, the concentration of reactants and products remains constant, as the rates of the forward and reverse reactions are equal. The equilibrium constant (K) also remains constant at a specific temperature. The Gibbs free energy of the system is at a minimum but remains constant at equilibrium.


In a reversible reaction two substances are in equilibrium if the concentration of each is doubled but the equilibrium constant remains unaffected?

TRUE


Why does the concentration of radon gas remains the faily constant although the radon gas decays?

The concentration of radon gas remains fairly constant because although radon decays, it is also being constantly produced from the decay of uranium and thorium in rocks and soil. This continuous production balances out the decay, leading to a relatively stable concentration of radon gas.


What characteristic of the atmosphere stays the same?

The composition of the atmosphere remains constant at different altitudes, with nitrogen making up about 78% and oxygen about 21%.
