Structure of the Earth the crust, upper mantle, lower mantle, outer core, and inner core. The geologic component layers of Earth are at the following depths below the surface: The layering of Earth has been inferred indirectly using the time of travel of refracted and reflected seismic waves created by earthquakes. The core does not allow shear waves to pass through it, while the speed of travel (seismic velocity) is different in other layers. The changes in seismic velocity between different layers causes refraction owing to Snell's law, like light bending as it passes through a prism. Likewise, reflections are caused by a large
What the Bleep Do We Know!? Theater in Portland, Oregon, where it was filmed. Within several weeks, the film had appeared in a dozen or more theaters (mostly in the western United States), and within six months it had made its way into 200 theaters across the US. According to the makers of the film, "Bleep" is an expurgation of "fuck". William Arntz has referred to the film as "WTFDWK" in a message to the film's street team. The Institute of Noetic Sciences, a New Age research organization that "explores phenomena that do not necessarily fit conventional scientific models", has supported "What the Bleep Do We
