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.
pressure at any given height is called an air mass. A single air mass may spread over millions of square kilometers and be up to 10 kilometers deep. Types of Air Masses Scientists classify air masses according to two characteristics: temperature and humidity. Four major types of air masses influence the weather in North America: maritime tropical, continental tropical, maritime polar, and continental polar. The characteristics of an air mass depend on the temperatures and moisture content of the region over which the air mass forms. Remember that temperature affects air pressure. Cold, dense air has
