It happens in the mantle. The middle layer of the Earth. The mantle's fluid or magma rises from the Earth's core. It becomes less dense. It travels away from the core cause of the tremendous heat and pressure. Once it cools off it cones back down. When it starts to heat back up again then it rises back up. It goes in a circular motion. That's convection current.
What else can I help you with?
What form of energy is used to cook pancakes convection or conduction?
covection?
What is a a result of the deflection of charged particles along the Van Allen belts?
covection of the atom
Why are covection currents needed?
Geologists believe that covection currents are what causes continental drift. If covection currents never happened and their force didnt move the continents then we'd all live on one large super continent.
What are the differences between the three methods of heat transfer?
Conduction, convection ,radiations are three methods of heat transfer. Conduction is carried out by direct contact with materials covection & radiation are carried out without any contact with the material
What is a covection current caused by diffences in what?
Convection currents are caused by differences in density. Warmer fluid is less dense, so a fixed volume of the warmer fluid is lighter. Colder fluid is denser, and so heavier in a fixed volume. The colder, denser fluid presses down and falls below the less dense fluid, which floats up to the top of the fluid. Often, there is a heat source that the bottom of the container, so the fluid at the bottom, which was more dense, warms up and becomes less dense. At the same time, the fluid at the top cools down and becomes more dense, and so the cycle repeats, forming a convection current.
What is the transfer of heat by the movement particles in fluids called?
its covection
The transfer of heat by the movement of particles in fluids is called?
its covection
Where do covection curennts take place?
I need to know the same thing
What is a result of the deflection of charged particles along the van Allen belt?
covection of the atom
Which layer of the Earth do Covection Currents occur in?
The major ones involve the mantle and the oceanic crust.
How long do you cook a 1 pound pork tenderloin in a covection oven?
i think it is about 2 hours i think it is about 2 hours

Why does the energy from the sun travel to earth by radiation instead of by covection or conduction?
The sun moves through the electromagnetic waves. Conduction and Convection transfers energy between differences in density.
How does Archimedes principle relate to covection?
I assume you mean "convection". The hotter liquid or gas is less dense, so it has less weight per unit volume, and it tends to float (move upward).
Why are covection currents needed?
Geologists believe that covection currents are what causes continental drift. If covection currents never happened and their force didnt move the continents then we'd all live on one large super continent.
What effect do covection currents and volcanic activity have on earth's surface?
When a part of the earth's upper mantle or lower crust melts, magma forms. A volcano is essentially an opening or a vent through which this magma and the dissolved gases it contains are discharged.
