The Earth and crust is a thin layer made up of?
The Earth's crust is made up of solid rock that is relatively thin in comparison to the rest of the Earth's layers. It is composed mainly of silicate minerals like feldspar and quartz, with the two most abundant elements being oxygen and silicon.
What is the percentage of oxygen provided by connecting a high flow of oxygen to the oxygen inlet found on a pocket mask?
Connecting a high flow of oxygen to the oxygen inlet on a pocket mask can deliver up to 50-60% oxygen concentration. The exact percentage may vary based on the oxygen flow rate, the patient's breathing pattern, and the mask's design. It is commonly used in emergency situations to provide supplemental oxygen to patients.
What is the most abundant element in the earth?
The most abundant element on earth is Oxygen. But due to its high reactivity, most oxygen occurs in combined state, generally in oxides.
Is oxygen scarce?
Oxygen is not scarce in the Earth's atmosphere, as it makes up about 21% of the air we breathe. However, access to oxygen can be limited in certain conditions such as high altitude, underwater, or in enclosed spaces with poor ventilation.
Why is there less oxygen in higher altitudes?
The higher you go the thinner the air gets. If you go to high, you could die from lack of air. > Jet fighters dont have pressurised cabins ( as commercial flights do) 25,000 feet is the crucial point, the lungs are incapable of absorbing oxygen at such low air pressure, a pressure demand mask overcomes this problem.
Where does blood pick up this oxygen?
Blood picks up oxygen in the lungs when it diffuses across the thin walls of the alveoli into the bloodstream. This oxygen is then carried by red blood cells to tissues throughout the body.
Why do people who climb high need gas masks?
Because of high altitude sickness which is affected by climbing up high were there is high altitude. High altitude is were there is to much oxygen up high, if you breech in to much oxygen you could faint.
Where is each string on the guitar?
they start at the bridge and make their way up to the head, thick to thin , low E than A , D, G, B than high E.
How do start up costs discourage entrepreneurs from entering a market?
When the start-up cost is high
How do mountaineers overcome the problem of a lack of oxygen?
Climbers need to wear oxygen masks to help them breathe as the air is thin higher up Mount Everest than at sea level.
What is Callisto's atmosphere made up of?
Callisto is surrounded by an extremely thin atmosphere composed of carbon dioxide and probalby molecular oxygen
Why must a mountain climber wear an oxygen mask?
because your way up high and their is not much atmosphere in the trophosphere and statoshpere so it could help wearing a mask to have to brethe! heavy clothes? not much gravity you need to weigh more then the usual on mountains or it will be so far but so close related to the moon!
What blood vessel has a high oxygen content?
The pulmonary vein carries blood from the lungs back to the heart, and it has a high oxygen content because the blood picks up oxygen in the lungs during gas exchange.
How high does oxygen reach in the Earth's atmosphere?
Oxygen in the Earth's atmosphere reaches up to about 100 kilometers above the surface.
What are the gases in Ganymede's atmosphere?
Ganymede, Jupiter's moon, has a thin atmosphere composed mostly of oxygen and hydrogen. These gases are present in very low concentrations compared to Earth's atmosphere. Ganymede's tenuous atmosphere is believed to be created by charged particles interacting with the moon's surface.
Where does the heart pump blood low in oxygen and high in carbon dioxide?
The heart pumps blood low in oxygen and high in carbon dioxide to the lungs, where blood releases carbon dioxide and picks up oxygen.
Why isn't it easy to breath on mount Everest?
The summit is so high up, therefore the air is very thin.
