Global pressure belts are regions of the Earth’s atmosphere characterized by similar pressure, temperature, and wind patterns. They are primarily divided into three categories: the equatorial low pressure belt, the subpolar low pressure belt, and the polar high pressure belt. The equatorial low pressure belt is located between the Tropics of Cancer and Capricorn and …
Humidity and atmospheric pressure are related in that when the humidity of the atmosphere increases, so does the pressure. This is because air molecules take up more space when there is a higher concentration of moisture in the air, thus increasing the atmospheric pressure. Generally, high-pressure systems are associated with clear skies and low-humidity conditions, …

Temperature and atmospheric pressure are directly related; as temperature increases, atmospheric pressure also increases. Conversely, when temperature decreases, atmospheric pressure will decrease. This is because when the temperature of the air increases, the molecules in the air move faster and spread out, increasing the pressure. When the temperature of the air decreases, the molecules slow …

Atmospheric pressure decreases with increasing altitude. This is due to the fact that as altitude increases, the atmospheric density decreases. The atmospheric pressure at sea level is approximately 1013.25 millibars, but this decreases as altitude increases. At an altitude of 10,000 meters, for example, the atmospheric pressure is approximately 200 millibars. The pressure also decreases …

Atmospheric pressure, or air pressure, is the force per unit area exerted by the weight of air in the atmosphere of Earth. It is measured with a barometer, and is most commonly expressed in units of hectopascals (hPa). Atmospheric pressure can vary significantly depending on factors such as latitude, altitude, weather conditions, and season. Generally, …

The Sun’s rays fall vertically between the Tropic of Cancer and the Tropic of Capricorn because these are the latitudes on Earth where the Sun is directly overhead at least once a year. These are the two most northern and southern points on Earth where the Sun is directly overhead during the summer and winter …
Standard time is a uniform time derived from a particular time zone. It is the prevailing local time of a region, established by law or custom. It is commonly used by countries and regions to regulate clocks and timekeeping. It was first introduced in 1883 as a standard way of determining time throughout the world. …
Greenwich Mean Time (GMT) is a time zone centered on the Greenwich meridian, which is the prime meridian used for international timekeeping. It is the same as Coordinated Universal Time (UTC). GMT is used in several countries around the world, including the United Kingdom, Ireland, Portugal, and Iceland. GMT is not the same as other …

The midnight sun is a natural phenomenon that occurs in the summer months in countries located in the northern latitudes of the Arctic Circle. It is characterized by the sun remaining visible at the local time of midnight. This phenomenon occurs due to the fact that the sun is above the horizon for 24 hours …
Utharayanam and Dakshinayanam are the two divisions of the year in the Hindu calendar. Utharayanam is the period of the year when the sun is in the north, and it marks the beginning of the Hindu year. Dakshinayanam is the period when the sun is in the south and marks the end of the Hindu …
