Cell membranes and plant cell walls are semipermeable barriers, which means that certain molecules can diffuse through them, while other molecules can not.</span>

How does air pressure affect weather
UNO [17]

Answer:

<em>Hewo, Kiluawa (sorry if i spelled it wrong) </em>

Explanation:

High Pressure

Basically, high pressure occurs in an area if the atmosphere over that particular area becomes heavier. As a result, the heavy air above will come down to the Earth’s surface. And the air present in that area will move away to create space for the heavy air.

Commonly, the warmer months experience high pressure. You’re more likely to enjoy a comparatively dry and stable weather pattern in those months. Besides, you’ll find the skies in high pressure areas very clear. You’ll also feel a gentle breeze there that will cool down the surrounding areas.

Low Pressure

On the other hand, the air above a low pressure area is comparatively much lighter than the air below. As the heavy air on the Earth’s surface cannot go further below, it pushes away the lighter air above. As a result, a vacuum is created on the surface level and the air in the surrounding areas rushes towards it to fill up the void space.

Meanwhile, the rising air starts to cool down and form clouds in the sky. These clouds then come down to the Earth in the form of rain. Sometimes, snow is also formed depending on the temperature of the surrounding areas.

In general, colder months of the year experiences more low pressure situations. By now, you probably can guess why. The cold air on the surface level is heavier than the air above. And these low pressure areas are the reasons behind unstable weather conditions like snow, ice, rain, storm, etc.
