Question

Как создаётся атмосферное давление​

Answer 1

Ответ:

Создается вследствие силы тяжести. Верхние слои воздуха давят на нижележащие.

Answer 2

How is atmospheric pressure created?

Atmospheric pressure is created by the weight of the air above a particular location on the Earth's surface. The Earth's atmosphere is composed of a mixture of gases, primarily nitrogen (about 78%) and oxygen (about 21%), along with trace amounts of other gases such as carbon dioxide, water vapor, and argon.

The force exerted by the weight of the air molecules above a given area creates atmospheric pressure. As you move higher in the atmosphere, the air becomes less dense, and therefore, the pressure decreases. Conversely, as you move closer to the Earth's surface, the air becomes denser, and the pressure increases.

The unit of measurement for atmospheric pressure is the pascal (Pa), although other units such as millibars (mb) and inches of mercury (inHg) are also commonly used.

Factors affecting atmospheric pressure

Several factors can influence atmospheric pressure, including temperature, altitude, and weather conditions. Here are some key points about these factors:

Temperature: Changes in temperature can affect atmospheric pressure. When air is heated, it expands and becomes less dense, leading to a decrease in pressure. Conversely, when air cools, it contracts and becomes denser, resulting in an increase in pressure.

Altitude: Atmospheric pressure decreases with increasing altitude. This is because there is less air above at higher altitudes, leading to lower atmospheric pressure. For example, at sea level, the average atmospheric pressure is around 1013.25 millibars (mb), while at the top of Mount Everest, the pressure is significantly lower.

Weather conditions: Weather systems, such as high and low-pressure systems, can also influence atmospheric pressure. High-pressure systems are associated with clear skies and stable weather conditions, while low-pressure systems are associated with cloudy skies and potentially stormy weather. These systems result from differences in air temperature and density, which in turn affect atmospheric pressure.

Verification of information

The information provided above is based on general knowledge about atmospheric pressure. However, I couldn't find specific snippets from the search results to directly cite the information. Therefore, it is important to note that the information provided is a general understanding of atmospheric pressure and its factors.
