Evolution Of The Theory Of Plate Tectonics Owlcation 4.1: the forces driving plate motions. the motion of tectonic plates is driven by convection in the mantle. in simple terms, convection is the idea that dense, cold things sink, and buoyant, warm things rise. in the earth the cold sinking things are slabs (subducting plates) and the warm things are plumes, or just rising material from deeper in. For example, the motion of tectonic plates is part of the convection cycles in earth’s mantle, which result in the formation of many features of earth’s land and undersea surface. many of earth's features can be observed from satellite images and maps (fig. 1). Geologists have hypothesized that the movement of tectonic plates is related to convection currents in the earth’s mantle. c onvection currents describe the rising, spread, and sinking of gas, liquid, or molten material caused by the application of heat. an example of convection current is shown in fig. 7.16. Figure 2. the lithospheric plates and their names. the arrows show whether the plates are moving apart, moving together, or sliding past each other. movement of the plates over earth’s surface is termed plate tectonics. plates move at a rate of a few centimeters a year, about the same rate fingernails grow.

Dissipation of heat from the mantle is acknowledged to be the original source of the energy required to drive plate tectonics through convection or large scale upwelling and doming. the current view, though still a matter of some debate, asserts that as a consequence, a powerful source of plate motion is generated due to the excess density of. The link between plate tectonics and mantle convection is one of the oldest and most challenging problems in the history of geodynamics. the original theories of mantle convection put forward by holmes (1931) were developed in the context of explaining continental drift as articulated by wegener (1924).
