Crust (geology) Crust (geology) In geology, the crust is the outermost solid shell of a rocky planet, dwarf planet, or natural satellite. It is usually distinguished from the underlying mantle by its chemical makeup; however, in the case of icy satellites, it may be distinguished based on its phase (solid crust vs. liquid mantle). The crusts of Earth, Moon, Mercury, Venus, Mars, Io, and other planetary bodies formed via igneous processes, and were later modified by erosion, impact cratering, volcanism, and sedimentation. Most terrestrial planets have fairly uniform crusts. Earth, however, has two distinct types: continental crust and oceanic crust. These two
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
