Does Earth's thick layer of atmosphere push down on us, increasing our weights drastically?
Exactly.blarznik said:So humans are slightly buoyant?
Let's assume you have a density of 1 g/cc. Some people float, some sink, so 1 g/cc is about right. Air at sea level has a density of about 1.2 kg/m3, so that means you displace about 2.9 ounces of air.If I weighed 150 pounds would it be relieving less than a pound?
That depends on what you mean by "weight" and what kind of scale you use to measure it.Allenbon said:It it true that in different parts of the Earth the weight of a particular human is different?
blarznik said:Also how thick would our atmosphere have to be to have it exert pressure on us? For instance like how at certain depths water pressure starts to overcome buoyant forces on an object.
The Earth's atmosphere plays a role in human weight by exerting pressure on the body. This pressure is known as atmospheric pressure or air pressure, and it increases as you move closer to the Earth's surface. This increase in pressure can cause a slight increase in a person's weight, usually by less than a pound.
Yes, the atmospheric pressure can vary in different locations on Earth. This variation is due to factors such as altitude, temperature, and weather conditions. For example, at higher altitudes, the atmospheric pressure is lower, which can cause a decrease in human weight. Conversely, at lower altitudes, the atmospheric pressure is higher, resulting in a slight increase in weight.
The composition of the Earth's atmosphere consists of various gases, including nitrogen, oxygen, and carbon dioxide. These gases have different densities, which can affect human weight. For instance, nitrogen and oxygen are less dense than carbon dioxide, so they contribute less to the atmospheric pressure. Therefore, a person may weigh slightly less in an area with a higher concentration of nitrogen and oxygen.
Yes, changes in atmospheric pressure can affect a person's weight. For example, when the atmospheric pressure decreases, such as during a thunderstorm, a person may feel as if their weight has slightly decreased. This is because the air pressure is lower, causing the body to expand slightly, resulting in a decrease in weight. However, these changes in weight are usually temporary and do not have a significant impact on overall body weight.
There are no significant health implications of changes in atmospheric pressure on human weight. As previously mentioned, changes in weight due to changes in atmospheric pressure are typically minor and temporary. However, high altitude and low atmospheric pressure can cause altitude sickness, which can lead to symptoms such as headaches, dizziness, and nausea. It is essential to acclimate slowly to changes in altitude to avoid these potential health implications.
