What Is Convection Current In Geography

Where convection currents converge plates move towards each other. Where convection currents diverge near the earth s crust plates move apart.

Geography is the science of the earth s physical feature resources climate and population so that is what geography is asked in science what does the word convection mean in science terms.

What is convection current in geography. A temperature difference leads to an energy transfer from an area of higher energy to one of lower energy. Such convection currents primarily move vertically and account for many atmospheric phenomena such as clouds and thunderstorms. Convection currents are flowing fluid that is moving because there is a temperature or density difference within the material.

Convection currents that occur within the molten rock in the mantle act like a conveyor belt for the plates. The driving force of mountain building implied by arthur holmes is provided by thermal convection currents originating deep within the earth. The convection currents move the plates.

The next time you heat anything like soup or pudding in a pan you can watch the convection currents move in the liquid. The heat transfer function of convection currents drives the earth s ocean currents atmospheric weather and geology. Tectonic plates move in different directions.

Atmospheric convection currents can be set up by local heating effects such as solar radiation heating and rising or contact with cold surface masses cooling and sinking. Heat rising and falling inside the mantle creates convection currents generated by radioactive decay in the core. Convection currents are caused by the very hot material at the deepest part of the mantle rising then cooling sinking again and then heating rising and repeating the cycle over and over.

The main source of the origin of convective currents is excessive heat in the substratum wherein disintegration of radio active elements generates heat regularly. Warm fronts being less dense will meet colder fronts and rise above them. The direction of movement and type of plate margin is determined by which way the convection currents are flowing.

Convection is a big part of how the earth s weather systems work. Convection currents transfer heat from one place to another by mass motion of a fluid such as water air or molten rock. Because particles within a solid are fixed in place convection currents are seen only in gases and liquids.

If those warm fronts contain enough water vapor the. The earth s crust is broken up into pieces called plates.
