Show What Is Fog? What is fog? Is it really a cloud on the surfact of the earth? YES, FOG is nothing more than a cloud. All clouds are formed when some kind of cooling process lowers low-ers the moisture and becomes visible visi-ble particles thus a cloud. This process can occur in several different ways and under different circumstances. In the fall, the fog is often seen in most parts of the country (the west coast experiences experi-ences much fog in winter). Fogs are usually caused when the earth (heated (he-ated during the summer) loses its heat into the cooler night air. AS THE warmer air from the earth's surface rises and is cooled, fog forms. Cold ground, in spring, for example, can make its own fog when warm moist air blows over it by colling the air to the cloud stage. Fog. then, is nothing more than a land-locked cloud. |
