oxygen is a constant 20 percent throughout the atmosphere. Even in space but the air is so thin in space that the oxygen would have to be compressed to be able to breathe it. Here on earth at sea level the atmospheric pressure is 14.7 pounds per square inch (PSI) making it possible for your body to inhale enough usable oxygen for you to breathe. As you go higher the pressure is less so even though the oxygen is still 20% of the atmosphere there is less atmosphere for you to breathe.
These reverse processes are both part of the water cycle
Carbon release from limestone reservoirs into the atmosphere most often occurs through human activities such as mining and quarrying operations. When limestone is extracted and processed, it can release carbon dioxide into the atmosphere, contributing to carbon emissions.

The oxygen atoms in CO2 come from the process of photosynthesis in plants. During photosynthesis, plants take in carbon dioxide from the air and water from the soil, and using sunlight as energy, convert them into glucose (sugar) and oxygen.
Nerve cells, also known as neurons, typically do not go through the cell cycle to divide and reproduce. They are terminally differentiated cells that do not undergo cell division once they have matured. This is why nerve cell damage or loss is often irreversible.
Medical oxygen is produced through a process called air separation, where oxygen is extracted from the atmosphere. This is often done using specialized equipment like oxygen concentrators or commercial plants that use cryogenic distillation to separate oxygen from other gases in the air. The resulting oxygen is purified and compressed for medical use.
The phosphorus cycle differs from the carbon and nitrogen cycles in various ways. Phosphorus primarily cycles through the lithosphere, while carbon cycles through the atmosphere, hydrosphere, and geosphere, and nitrogen cycles through the atmosphere and biosphere. Phosphorus is often a limiting nutrient in ecosystems, while carbon and nitrogen are more abundant and play larger roles in atmospheric processes.
Carbon Dioxide: is a chemical compound composed of one carbon and two oxygen atoms. It is often referred to by its formula CO 2 . It is present in the Earth's atmosphere at a low concentration and acts as a greenhouse gas. In its solid state, it is called dry ice. It is a major component of the carbon cycle.
mercury's atmosphere is thin so sound waves don't travel very well and there is little oxygen.
Phosphorus, often leached from rocks and minerals, is an important component of soils. Phosphorus does not have an atmospheric form, so it is most often transported by water. Inorganic phosphorus is taken in by plants, incorporated into organic compounds, and moves up the food chain. Phosphorus is returned to the soil and rock cycle through decomposition of waste.

Yes, ions can be found in the Earth's atmosphere. These ions are often formed from the interaction of sunlight with molecules in the atmosphere, such as nitrogen and oxygen. Ions play a role in processes like lightning strikes and the formation of the Earth's ionosphere.
Nitrogen gas makes up around 78% of Earth's atmosphere, whereas oxygen gas accounts for about 21%. This difference is due to the nitrogen-fixing abilities of certain bacteria and the fact that oxygen is more reactive and is often consumed through processes like respiration and combustion.
The oxygen atoms in CO2 come from the process of photosynthesis in plants. During photosynthesis, plants take in carbon dioxide from the air and water from the soil, and using sunlight as energy, convert them into glucose (sugar) and oxygen.
There are two ways to give oxygen to a patient. You can deliver it through a face mask, connected to a tank of oxygen, or you can place the patient in a room which has its own pure oxygen atmosphere, often at high pressure as well. High pressure (technically called hyperbaric) oxygen will enter the blood even if the patient is not breathing.
