## How is the atmospheric pressure distributed on the Earth surface?

The distribution of atmospheric pressure across the latitudes is termed as global horizontal distribution. On the earth’s surface, there are in all seven pressure belts. The seven pressure belts are: equatorial low, the sub-tropical highs, the sub-polar lows, and the polar highs.

## How does atmospheric circulation distribute heat energy?

The air separates and starts to move both north and south towards the poles. When it reaches about 30° north and south, the air cools and sinks towards the ground forming the subtropical high-pressure zone. As the air sinks, it becomes warmer and drier.

## How is energy transferred in the atmosphere?

Energy is transferred between the Earth’s surface and the atmosphere in a variety of ways, including radiation, conduction, and convection. Conduction is one of the three main ways that heat energy moves from place to place. The other two ways heat moves around are radiation and convection.

## What does pressure distribution in the atmosphere control?

Atmospheric pressure and wind are both significant controlling factors of Earth’s weather and climate. Distributions of pressure on a map are depicted by a series of curved lines called isobars, each of which connects points of equal pressure. …

## What causes high and low atmospheric pressure?

Areas of high and low pressure are caused by ascending and descending air. As air warms it ascends, leading to low pressure at the surface. As air cools it descends, leading to high pressure at the surface.

## What are the four global pressure belts?

These belts exist in pattern of alternate high and low pressure zones over the earth and they are four in numbers: equatorial low pressure belt, sub-tropical high pressure belt, sub-polar low pressure belt and polar high pressure belt (Figure below).

## What are the 3 pressure belts?

They are the Equatorial Low, the two Subtropical highs, the two Subpolar lows, and the two Polar highs. Except for the Equatorial low, the others form matching pairs in the Northern and Southern Hemispheres. There is a pattern of alternate high and low-pressure belts over the earth.

## What is the average air pressure at sea level?

1013.25 millibars

## Why is air pressure greatest at sea level?

Most gas molecules in the atmosphere are pulled close to Earth’s surface by gravity, so gas particles are denser near the surface. With greater depth of the atmosphere, more air is pressing down from above. Therefore, air pressure is greatest at sea level and falls with increasing altitude.

## What is the best air pressure for humans?

3 Answers. This answer has been awarded bounties worth 50 reputation by SF. Disregarding hypoxia, the lowest atmospheric pressure the human body can withstand is around 6 percent sea level pressure, or 61.8 millibars, below that pressure the water and blood in your body starts to boil.

## What is a good air pressure?

between 30 and 35 PSI.

## Is 40 psi good tire pressure?

Normal tire pressure is usually between 32~40 psi(pounds per square inch) when they are cold. So make sure you check your tire pressure after a long stay and usually, you can do it in the early morning.

## Why do dealers overinflate tires?

Tires are overinflated during the shipping process, so as to help prevent the flat spot from forming in the tire as it sits for days on in during the shipping process. It is supposed to be part of the delivery check process that the service department deflates the tires to the proper pressure.

## Is 38 psi too much?

The average passenger automobile/SUV/light truck has a recommended tire PSI of 30 to 35. If you allow your tire pressure to drop any more than 5 PSI below recommended you will significantly lose handling, stability can control.

## Is 50 psi too much for tires?

Every tire has a rated maximum inflation pressure. Often it will be found in small print around the rim edge of the sidewall. This means that the tire will safely carry up to 1477 lbs. and can be safely inflated up to 300 kPa (Kilopascal) or 50 psi (pounds per square inch).

## What happens if tires are overinflated?

Overinflated Tires Wear Out Your Tires Faster & Unevenly When your tires have too much air it causes the center of the tread to bow out and wear first. Because of this you will need new tires more often and have a less than comfortable ride.

## Is it dangerous to drive with overinflated tires?

Compromised Safety. There are a variety of issues that can occur if you drive on overinflated tires. Most seriously, overinflated tires are at greater risk for a blowout. A tire blowout can cause you to lose control of your vehicle and negatively affect braking distance, endangering yourself and others on the road.

## Is letting the air out of tires illegal?

A: You would be breaking the law whether you damaged the tire or not. Simply letting the air out would be a violation of the law for the inconvenience caused the owner. You would also be responsible for any amount the person paid for towing or tire service.

## How can I flatten my tires fast and quietly?

How to Flatten Tires Quickly and Quietly

1. Take a pocket knife, preferably a serrated one like the Spyderco Atlantic Salt.
2. Stand while facing away and the tire between your legs.
3. Start making small radial cuts on the tire sides.
4. After several cuts, push the knife into the tire at an angle.

## Why are you only supposed to stab 3 tires?

Because their insurance won’t cover just 3. For insurance to cover tire replacement, it has to be all 4. I think for insurance purposes. Insurance will cover if all 4 are slashed; they won’t cover 3 tires.

## Is slashing a tire loud?

What is slashing? As the name implies, slashing a tire means making a deep cut with a sharp tool (typically a knife or a nail) to deflate the tire. Slashing can be quite loud if the tire is not depressurized.

## Will a tire explode if you stab it?

It is very unlikely that a tire will explode. It would have to be very over inflated. If you stab a sharp object into a regular tire nothing bad is going to happen unless your hand slips and you cut yourself. An exploding tire is a thing that can happen while you’re driving.

## How do I know if my tire was stabbed?

An icepick or awl would leave a perfectly round hole, like a nail, but no nail or evidence of road wear is seen. Typically when a tire is slashed, more than one tire is vandalized at a time, but popping a tire makes a very loud noise which may have scared an amateur off.

## What can slash tires?

You can slash a tire using different tools. The most common ones are nails and a strong pocket knife. Using a bigger knife will get the job done quickly, but it will be a bit out of order to carry it around all the time. This is the sure way of puncturing a tire.

## Will slashing tires set off a car alarm?

Unfortunately slashing tires doesn’t produce much vibrations. It doesn’t even require the person to touch the car directly. So it’s not very likely that a basic alarm would get triggered.

5. Start a neighborhood crime watch if this is happening repeatedly in your neighborhood.

## Are there slash proof tires?

Unfortunately the answer is no, at least for any tires made to fit civilian vehicles. The side walls would have to be made of a material or extreme thickness impervious to the slicing action of a knife.
