Structure of the Earth decay of radioactive elements, and freezing of the inner core. Structure of the Earth The internal structure of the Earth is layered in spherical shells: an outer silicate solid crust, a highly viscous asthenosphere and mantle, a liquid outer core that is much less viscous than the mantle, and a solid inner core. Scientific understanding of the internal structure of the Earth is based on observations of topography and bathymetry, observations of rock in outcrop, samples brought to the surface from greater depths by volcanoes or volcanic activity, analysis of the seismic waves that pass through the Earth, measurements of
What the Bleep Do We Know!? film has been described as an example of quantum mysticism, and has been criticized for both misrepresenting science and containing pseudoscience.

Filmed in Portland, Oregon, "What the Bleep Do We Know!?" presents a viewpoint of the physical universe and human life within it, with connections to neuroscience and quantum physics. Some ideas discussed in the film are: In the narrative segments of the movie, Marlee Matlin portrays Amanda, a photographer who
