Largest Peninsulas of World : Arabian Peninsula. Arabian Peninsula or Arabia is the largest peninsula of world which occupies an area of 3.2 million square Km. It is located in middle east and comprises of 7 countries including Saudi Arabia, Oman, Yemen, UAE, Kuwait, Bahrain and Qatar.
Pressure is merely force per area, so if the force increases but the box stays the same size, the pressure has increased. Air density can decrease with temperature if pressure is also decreasing. If pressure is constant, this cannot happen (they would be inversely related). Any time you specify a relation between any two of pressure, density or temperature you must hold the third constant or specify its behavior.
We live at the bottom of the atmosphere and the weight of all the air above us is called air pressure. A tower of air that is 1 inch square and goes from the bottom of the atmosphere is 14.7 pounds. That means air exerts 14.7 pounds per square inch (psi) of pressure at the Earthâs surface. High in the atmosphere, air pressure decreases. With less air molecules above, there is less pressure from the weight of air above. Pressure varies from day-to-day at the Earthâs surface - the bottom of the atmosphere. This is, in part, because the Earth is not equally heated by the Sun. Areas where air is warmed often have lower pressure because the warm air rises and are called low pressure systems. Places where air pressure is high are called high pressure systems. A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet. As the air rises, the water vapor within it condenses forming clouds and often precipitation too. Because of Earthâs spin and the Coriolis Effect, winds of a low pressure system swirl counterclockwise north of the equator and clockwise south of the ...
