Question

Which of the following factors affect atmospheric pressure?
(A) Altitude
(B) Temperature and amount of moisture
(C) Rotation of the earth
(D) All of the above

Answer 1

Hint: The weight of air is known as air pressure. Air is a composition of diverse gases therefore it has a particular weight. The weight of air on any unit of vicinity on the planet is called air strain at the same time as it's far represented in the pressure unit.

Complete answer:
Division of temperature isn’t always comparable at all of the locations on the earth. Because of the temperature difference, air stress also varies immensely. Air dilates in summer because of excessive temperature and in wintry weather, it shrinks because of low temperature. As the temperature rises, air enlarges due to which its density decreases which ends up in low force. Alternatively, air shrinks due to low temperature because of which its density increases which creates excessive pressure. Transformation of water from a fluid state to a vaporous state because of evaporation is called atmospheric Dampness. Vapors from water are thin in weight consequently they rise and the stress of humid air decreases in comparison to dry air. The quantity of water vapors changes with time and place and due to this the strain of air additionally varies. Air stress is caused due to the weight of air, hence the sea has maximum air pressure. As we flow upward from sea degree leaving back the heavy gases at the bottom-most layers of the atmosphere, air strain decreases due to the fact the upper air is light and its density is low. There is no fixed charge of fall in the air force with growth in the top but it decreases with an increase in peak. The gyration of Earth produces a centrifugal force which has more effect in Torrid location even lesser effect on Polar regions. Centrifugal pressure pushes matters far from its core. The same is the impact on air pressure which results in lesser stress in Equatorial regions as compared to that during polar areas.

Thus, option (D) is correct.

Note: Don’t get confused between factors affecting atmospheric pressure and factors controlling pressure systems as the latter includes Thermal and Dynamic factors for the strain differences resulting in high and fewer stress structures.
