Deserts are vast land areas that receive very little rainfall and have sparse vegetation. A region is considered a desert if its annual precipitation is below 250 mm. However, the term desert does not only refer to high temperatures but also means aridity.What Are the Characteristics of a Desert Climate?In desert climates there is a large temperature difference between day and night. During the day, sunlight directly reaches the ground and the air heats up significantly. However, when night fall

Jet stream is the term used for very fast air currents that flow at high altitudes, even above the regions where airplanes fly. These winds generally blow from west to east and can be thought of as long, narrow rivers of air encircling the Earth.Where Do They Form?Jet streams form in the upper part of the troposphere, the lowest layer of the atmosphere, at altitudes of approximately 10 to 15 kilometers. They are typically found in the mid-latitudes of both the Northern and Southern Hemispheres a

The Seebeck effect is the phenomenon in which an electrical potential difference arises in a closed circuit formed by joining two different conductive or semiconductive materials when a temperature difference is created between their junctions. It was discovered in 1821 by the German physicist Thomas Johann Seebeck. Seebeck observed that when he heated one junction of a circuit made from two dissimilar metal wires the compass needle deflected and initially believed the effect to be magnetic. How
