The Pratt and Airy models describe the gravitational equilibrium of these objects, called isostasy, while Vacquier noticed magnetic striping in them.
The Pratt and Airy models describe the gravitational equilibrium of these objects, called isostasy, while Vacquier noticed magnetic striping in them. They are found above the asthenosphere, and their movement is controlled by factors including basal drag and(*) slab suction. Two of these objects grind alongside one another at transform boundaries, which include the San Andreas Fault. A subduction zone is often created where an oceanic one meets a continental one. The Nazca and Juan de Fuca are examples of, for 10 points, what large slabs of rock that make up the Earth's crust?
