WebRidge Push (fig. 2) has been considered in two different manners, as a body force and as a boundary force. As a body force, ridge push has been attributed to the cooling and thickening of the oceanic lithosphere with age (McKenzie, 1968; McKenzie, 1969; Richards, 1992; Vigny et al., 1992). This type of force can be thought of as created by the horizontal … WebThermal convection. Ridge push. Slab pull. Trench suction. All answers are correct. 2.
