The mantle transition zone (TZ) is the layer between two discontinuities in seismic wave-speed that lie at depths of approximately 410 km and 650 km [Anderson, 1989]. These discontinuities are polymorphic phase changes, caused by pressure-induced changes of crystal structure in certain minerals [Anderson, 1967].

What is a transition zone in human geography?
Explanation: The Transition Zone consists largely of low-quality housing that is close in proximity to industrial and manufacturing jobs in the Commercial Business District (CBD). Since the housing in this zone tends to be unpleasant, its cost is low and the proximity to entry-level jobs attracts low-income families.
