What Does CMB Stand For?

CMB stands for Core Mantle Boundary

The Core Mantle Boundary (CMB) is the interface that separates Earth's outer core from the underlying mantle. Located approximately 2,900 kilometers beneath the Earth's surface, the CMB plays a crucial role in geodynamics and the planet's thermal and compositional structure. This boundary is characterized by a dramatic change in material properties, transitioning from the liquid metal of the outer core to the solid rocky mantle, which influences seismic wave propagation and contributes to our understanding of Earth's geology and magnetic field generation.
