Compare air at 18000 feet to air at sea level?
Air at 18,000 feet has lower pressure, lower oxygen levels, and is colder than air at sea level. The decrease in pressure can affect breathing and require acclimatization, while lower oxygen levels may cause altitude sickness. The colder temperature at higher altitudes can also impact human comfort and performance.
Why do air over the sea moist?
The air over the sea is moist because the sea water is constantly evaporating. This creates a dense sea fog or sea mist.
Is sea-level pressure determined by both the amount of air in the atmosphere and the strength of the Earth's gravity?
Yes, sea-level pressure is determined by the weight of the air above a specific location due to gravity. The greater the amount of air molecules in the atmosphere, the higher the pressure. Changes in gravity will affect pressure readings, such as at higher elevations where there is less gravitational pull compared to sea level.
How would the air pressure at the Dead Sea affect the boiling point of water?
The Dead Sea is below mean sea level for the earth; therefore, the pressure at the Dead Sea would be greater than at mean sea level and the boiling point of water would be above 100C.
Warm air over cold water results in?
Warm air over cold water results in a phenomenon known as sea fog. This occurs when the warm, moist air cools down upon contact with the cold water, leading to condensation and the formation of fog. Sea fog can reduce visibility and affect navigation for ships.
The height of land above sea level is?
...a good thing for air-breathing creatures.
How do you find out if there is air in water?
air is in the water because although sea animals use this while breathing under the water
How do you find out if there's air in water?

Is it hard breathing 2600 ft above sea level?
Because there is not that much air like it is on the ground
Why is it easier to breathe at sea level than at higher altitudes?
At sea level, the air pressure is higher, which means there is more oxygen available for breathing. At higher altitudes, the air pressure decreases, making it harder for the body to take in enough oxygen, leading to difficulty in breathing.
How does technology effect air quality?
Technology in the land, sea and air will surely contribute air pollution thus will also affect the air quality.
What is the air pressure at 14000 feet?
At 14,000 feet, the air pressure is significantly lower than at sea level, typically around 11.6 pounds per square inch (psi) or approximately 26.5 inches of mercury (inHg). This pressure can vary based on temperature and weather conditions, but it is generally about 60% of the sea level pressure. At this altitude, the reduced air pressure can affect breathing and is a consideration for climbers and aviators.
How does heat transfer affect weather?
convection currents rush cool air to the sea
Where does it live dolphins?
Dolphins are air-breathing, aquatic mammals, and live in the sea, though certain species live in rivers and estuaries.
What happens to air pressure when you rise up words in the atmosphere?
As you rise upwards in the atmosphere, air pressure decreases. This occurs because the density of air molecules diminishes with altitude, leading to fewer molecules exerting pressure. Consequently, higher elevations experience lower air pressure compared to sea level. This decrease in pressure can also affect breathing and the boiling point of liquids.
What is the highest PaO2 one could expect to observe in an individual breathing room air at sea level?
The highest PaO2 one could expect to observe in an individual breathing room air (FiO2 of 0.21) at sea level is around 100 mmHg. This is because the atmospheric pressure at sea level is around 760 mmHg, and oxygen normally makes up about 21% of the atmosphere.
What happens to air pressure when you move upward away from sea level?
Air pressure decreases as you move upward away from sea level due to a decrease in the weight of the air above. This decrease in pressure can cause discomfort in the ears and reduce the availability of oxygen for breathing at higher altitudes.
