What causes a pyroclastic flow?
GeologyA pyroclastic flow is extremely hot, burning anything in its path. It may move at speeds as high as 200 m/s. Pyroclastic flows form in various ways. A common cause is when the column of lava, ash, and gases expelled from a volcano during an eruption loses its upward momentum and falls back to the

What is the cause of Geodynamo?
GeologyIt is caused by electric currents which are generated in the same way as with a self-excited dynamo: by the movement of an electrical conductor in a magnetic field. This ‘geodynamo’ is driven by the thermal convection of the liquid iron inside the Earth. What does the geodynamo do? Circulation in Earth’s molten outer core
