The earth is composed of mainly 3 layers: crust, mantle and the core. The crust is the outer layer of the earth. It is a thin layer between 0-33 km thick. The crust is the solid rock layer upon which we live. The mantle is the widest section of the earth. The mantle is made up of semi-molten rocks called magma. Mantle can be further divided into upper mantle and lower mantle. Upper mantle lies between 33-670 km below the earth's crust and the rock is typically hard in this layer. Lower mantle lies between 670-2900 km below the earth's crust and consists of semi-molten rocks. Core is the innermost layer of the earth. It is further divided into upper core and inner core. Inner core is the center and the hottest part of the earth. It is solid and made up of iron and nickel with temperatures of up to 5500ΒΓC. It lies between 5150-6370km below earth's crust. Outer core is the layer surrounding the inner core. It is a liquid layer made up of iron and nickel with temperatures similar to inner core. It lies between 2900-5150 km below the earth's crust. | 0.721549 |

P | c | T_0751 | text | null | Crust, mantle, and core differ from each other in chemical composition. Its understandable that scientists know the most about the crust, and less about deeper layers (Figure 6.3). Earths crust is a thin, brittle outer shell. The crust is made of rock. This layer is thinner under the oceans and much thicker in mountain ranges. | 0.614295 |

P | c | T_1855 | text | null | Volcanoes erupt because mantle rock melts. This is the first stage in creating a volcano. Remember from the chapter Materials of Earths Crust that mantle may melt if temperature rises, pressure lowers, or water is added. Be sure to think about how and why melting occurs in the settings where there is volcanism mentioned in the next few concepts. | 0.60132 |

P | c | T_1194 | text | null | Lighter materials accumulated at the surface of the mantle to become the earliest crust. The first crust was probably basaltic, like the oceanic crust is today. Intense heat from the early core drove rapid and vigorous mantle convection so that crust quickly recycled into the mantle. The recycling of basaltic crust was so effective that no remnants of it are found today. | 0.58574 |

P | c | T_1864 | text | null | At divergent plate boundaries hot mantle rock rises into the space where the plates are moving apart. As the hot mantle rock convects upward it rises higher in the mantle. The rock is under lower pressure; this lowers the melting temperature of the rock and so it melts. Lava erupts through long cracks in the ground, or fissures. | 0.570783 |

Like a bar magnet, Earth has north and south magnetic poles. A magnetic pole is the north or south end of a magnet, where the magnet exerts the most force. | 0.561196 |

The properties fit the ultramafic rock peridotite, which is made of the iron- and magnesium-rich silicate minerals (Figure 1.1). Peridotite is rarely found at Earths surface. | 0.553937 |
