How do convection currents work in the mantle?
What forces would lead to the movement of the plates over the surface of the earth? At this time it is believed this movement results from mantle convection. Deep within the earth there is a large amount of heat coming from two sources: the magma remnants of the Great Bombardment, and radiation from radioactive elements. This heat, in accordance with the 2 ndlaw of thermodynamics, must flow to a cooler place, and subsequently rises to the surface of the Earth. If the Earth were smaller, this heat would flow by conduction, but because of the relatively large size of the Earth, convection also takes place. Thus, as in heating a pot of water on a stove, convection currents are established within the earth, which bring warm material to the surface and send cooler material to the interior.
Who destroyed the Parthenon?
