What Is Convection Current In The Mantle
The earth is made out of a number of different layers and though we live on the crust of the earth there are miles of earth beneath our feet. It is thought that heating of the mantle by the core creates convection cells in which hot mantle material rises cooling as it goes toward the crust until it reaches less dense material at which point it spreads out then descends.
Convection in earth geologists believe the molten rock deep within the earth circulates by convection currents.
What is convection current in the mantle. Convection currents in the mantle result from the temperature difference between the top and bottom of the mantle. The direction of movement and type of plate margin is determined by which way the convection currents are flowing. Convection usually refers to particle movement in fluids but solids can also flow.
Without these movements of the magma we wouldn. The movement of the currents plays a factor in the movement of the mantle. In the case of the earth convection currents refer to the motion of molten rock in the mantle as radioactive decay heats up magma causing it to rise and driving the global scale flow of magma.
Mantle convection is the very slow creeping motion of earth s solid silicate mantle caused by convection currents carrying heat from the interior to the planet s surface. Mantle convection is the process by which heat from the earth s core is transferred upwards to the surface. The mantle is the mostly solid bulk of earth s interior.
Convection happens when particles move from high temperature to low temperature areas in a material. The mantle lies between earth s dense super heated core and its thin outer layer the crust. Because of this temperature difference the liquid magma in the earth s mantle also contains convection currents just like a pot of boiling water.
Convection currents are the movement of fluid as a result of differential heating or convection. Convection currents that occur within the molten rock in the mantle act like a conveyor belt for the plates. Convection currents develop in the atmosphere as well resulting in the formation of winds and clouds.
Tectonic plates move in different directions. The earth s surface lithosphere rides atop the asthenosphere and the two form the components of the upper mantle. Convection current develops in the mantle of the earth due to the repeated heating and cooling cycles of the magma.
Convection currents in earth s mantle are caused by the rise of hot material rising towards the crust becoming cooler and sinking back down. The rock is in a semi liquid state and should behave like any other fluid rising up from the bottom of the mantle after becoming hotter and less dense from the heat of the earth s core. The mantle is about 2 900 kilometers 1 802 miles thick and makes up a whopping 84 of earth s total volume.
This also acts as the foundation of the plate or tectonic movements. This process occurs repeatedly causing the currents to constantly flow.
