At the bottom of a substance, part of it is heated by something. This causes it to rise above the rest. However, it soon cools and drops back down again where it is then heated, etcetera. This forms a constant current of part of the substance rising then dropping and repeating.

The effects of convection currents in the mantle are an overall movement of magma, the shifting of plates, and the even distribution of heat. This helps to reduce the amount of earthquakes and volcano eruptions.

What happen as thermal energy is transferred from the core to the mantle?
CONVECTION CURRENT is the answer.
Where convection can happen?
convection happens in liquid
What will happen if the heating element is near the top of an electric kettle?
The kettle will be less efficient because it won't be benefitting from the effects of convection currents. It will use considerably more energy.
Is a coffie pot a type of convection?
No because convection can only happen in liquids or gases.
Does convection happen when hot water displaces cold water?
Sort of. In truth, convection happens mainly over a heat source, and not just with water (one example is the Earth's inner mantle). The hotter material closer to the source rises (because the molecules have more kinetic energy), but loses that energy once it reaches the surface, sinking back down as it gets slightly more cool and dense. Since this is a continuous cycle, convection "currents" often occur. Check out this link for a picture of convection currents: http://upload.wikimedia.org/wikipedia/commons/f/f5/ConvectionCells.svg
What will happen to the convection currents in the mantle if the earths interior cools down?
the convection currents will stop
What will happen to convection currents in the mantle if earth's interior eventually cools down?
the convection currents will stop
What will happen to the convection currents in the mantle if Earth's interior eventually cooled down?
The convection currents will stop
What happen as thermal energy is transferred from the core to the mantle?
CONVECTION CURRENT is the answer.
What will happen to the convection currents in the mantle if the Earth's interior cools down?
If Earth's interior cools to a non liquid state, the convection currents will stop.
What will happen to the convection current in the mantle if Earth's interior eventually cools down?
the convection currents will stop
What will happen to the convections currents in the mantle if Earth's interior eventually cools down?
the convection currents will stop
What do you think will happen to the convection current in the mantle if the interior of earth eventually cools down?
the convection currents will stop
Where do convection currents happen?
Convection currents occur in any fluid in which there is a temperature differance. Most convection currents occur in the mantle, the layer of semi-liquid rock below the crust. These currents are the reason behind plate tectonics.
What happends to convection currents when the liquid or gas is no longer heated?
It falls back down
What would happen to the convection currents in the mantle if the earths interior cooled down?
the convection currents will be set in motion because the heat from the mantle rises and causing it to change Earth's density & force of gravity
What will happen to the convection currents in the mantle if earth's interior cools down?
Convection currents are transferring heat to the surface through the movement of mantle rock. If the interior of the planet cools, the mantle rock would be too solid to move, and there would be no heat to transfer.
