What are convection currents?
Convection currents are movements caused by changes in temperature in liquids or gaseous bodies. In such bodies, the warmer material tends to rise and move a colder mass that spreads elsewhere; Continuous movement created by this process is known as a convection cell. Conventional currents are responsible for many phenomena in the natural world, although their meaning is often overlooked. Oceans, storm clouds and Earth's crust are all large systems affected by these currents. On smaller scales, they can be observed in a pot of boiling water or a cup of coffee.
The heat causes the individual molecules to move quickly. In the liquid, which in this case means any liquid or gaseous substance, these heated molecules are expanding and less dense. This causes them to rise in liquid and move colder molecules already present. These cooler molecules will move elsewhere in the liquid; If they come across a heat source, they become upset and climb, while the previously heated moleThe uly cool down and descend. This effect creates convection cells that in turn cause convection currents.
Convection currents cause effects that can be seen in a pan with water heating on the stove. The water at the bottom of the pelvis, closest to the burner, heats up quickly and rises to the surface. Bubbles show the agitation of heated water molecules that circulate heat until all water is boiled. The effect is easier to observe pouring the cream into a hot cup of coffee. Even without mixing, the cream begins to circulate through warmer coffee and the color difference in two liquids makes it easy to observe convection patterns.
On a very large scale, convection currents follow the movement of the atmosphere around the ground. The air heated by the sun moves to colder areas and areas, causing a change in weather patterns. Trainable are formed when warm air with humidity rises and encounters cooler air at higher altitudes. Actions of convection cells on clouds cancause thunderstorms and sometimes more spectacular events. Tornadoes and hurricanes are the result of violent air distribution and humidity caused by a moving atmosphere.
Among their other effects are convection currents also responsible for earthquakes and seismic activity. The ground surface consists of a series of solid masses that float on the currents of liquefied rocks. This underground liquid, called Magma, is subject to the movement of convection cells, as well as other liquids. Conventional currents in magma can cause ground masses called tectonic boards to rise or knock each other. This may result in volcanic eruptions, earthquakes and other catastrophic seismic activity.
