How is a convection current made?

Answer 1

Heat up air or water and a convection curent wil form as the heated air or water starts to move upwards. An array of several convection tubes are positioned in a series configuration to provide the equivalent of a very tall convection current generating tower, the pressure and fluid flow of the array thereby becoming capable of significant pressures such as the pressures necessary to move solar heated air into the confines of a rock storage area, the pressure increases of this array being achieved by the additive effects of connecting heated and cooled convecting columns together alternately in such a way that the output of one is connected to the input of another.

Answer 2

well, a convection current is mainly caused by the heat from the cores. Since the heat from the cores are so hot, it moves the mantle (the semi-molten rocks), just like a water boiling. So, as the mantles move up from the heat, it comes in contact with the crust, a cooler layer. The mantle grazes under the crust until it loses heat and comes back down again. Then the cycle continues due to the heat from the cores. I'm sure there's more to do with the density of a heated mantle and all that stuff, but i don't really know the details.. i hope this answered your question enough though.

Answer 3

Yes they do.
