Webslab pull process Most agree that plate movement is the result of the convective circulation of Earth’s heated interior, much as envisaged by Arthur Holmes in 1929. The heat source for convection is thought to be the decay of radioactive elements in the mantle. How this convection propels the plates is poorly understood.

WebThe Earth is roughly spherical, so these plates are fractured into curved sections which are in constant motion relative to each other and meet in various ways along their edges – these are the ‘plate boundaries’, where most volcanoes and earthquakes occur. WebSlab pull is the gravitational pull that causes the denser plate to move further after subduction. How many tectonic plates are there? There are seven major tectonic plates.
