Admin Where do you expect the pressure to be high at the equator?
The amount of heat radiation is of maximum at the equator. The cold air at the poles is denser than the warm air at the equator; hence, air pressure at sea level is higher at the poles than at the equator.
Is air pressure greatest near the equator?
The lowest portion of Earth’s atmosphere, the troposphere, is wider at the equator (10 mi) than at the poles (5 mi). So the further north or south you go from the equator, the lower the air pressure will be at a given altitude.
What is air pressure Where is the air pressure high at the equator or at the poles justify your answer?
“The air pressure is higher at the poles. The cold air is always denser than the “warm air”. So, we can say that, the “air is denser” at poles compare to the equator. The pressure and density is directly proportional. The denser air causes higher “air pressure” at the poles than at the equator.
Does the equator have lower air pressure than the Poles?
There may be more storms near the equator than at the poles, giving rise to lower pressure zones. So the pressures are all the same for water at the surface of the ocean.
Is air pressure higher at the equator or the poles?
Explanation: Air pressure is highest at the equator, and much lower at the poles. Guy-Lussac’s Law states that pressure is proportional to temperature at constant volume. Often people think that low pressure areas are warmer, however this is only the case where volume is not constant.
What type of pressure occurs at the equator Why?
low pressure
A. Equatorial regions is hotter and the air above expands, becomes less dense and rises. This produces a low pressure belt at this latitude.
Does air sink at the equator?
In review, on a non-rotating earth, warm air would rise at the equator, go to the poles, sink to the surface, and flow back to the equator. But because the earth rotates, air is deflected from this path. Air rising at the equator only gets about 30° N and sinks back down to the earth, making the Hadley cell.
