| 6164464120 | Core | the innermost zone of the planet made out of nickel and iron |  | 0 |
| 6164464121 | Mantle | above the core containing magma (molten rock) |  | 1 |
| 6164464122 | Crust | the outermost layer of the planet; what we walk on | | 2 |
| 6164464123 | Lithosphere | the brittle outermost layer of the planet (about 100km thick) |  | 3 |
| 6164464124 | Asthenosphere | the outermost part of the mantle, composed of semi-molten rock |  | 4 |
| 6164464125 | Mesosphere | "meso" means middle. rock in this layer flows more slowly than in the asthenosphere |  | 5 |
| 6164464126 | Outer core | liquid layer composed of nickel and iron | | 6 |
| 6164464127 | inner core | dense solid layer made of nickel and iron | | 7 |
| 6164464128 | what are the pros (environmental) of volcanoes? | creates new land, releases nutrients, commercially valuable products such as: pumice, metals, stones). | 8 | |
| 6164464129 | Plate Tectonics | the theory that states that Earth's surface is divided into plates, most of which are in constant motion |  | 9 |
| 6164464130 | Oceanic plates | lie primarily below the ocean; crust is dense and rich with iron |  | 10 |
| 6164464131 | Continental plates | lie beneath the land masses; made of lighter materials like silicon dioxide; this less dense material makes plates rise above oceanic when they collide. | | 11 |
| 6164464132 | Divergent Boundaries | plates moving away from each other to create new land. This movement creates valleys, rifts, and ridges |  | 12 |
| 6164464133 | Mid ocean ridges | a deep underwater mountain range formed by diverging oceanic plates. EX: Mid-Atlantic Ridge |  | 13 |
| 6164464134 | Rift Valleys | A long, straight, deep valley produced by the separation of crustal plates. EX: Great rift valley |  | 14 |
| 6164464135 | Convergent Boundaries | plates move toward each other, often destroying land; this forms mountain ranges |  | 15 |
| 6164464136 | Subduction Zones | when the MORE dense plate is pushed underneath the LESS dense plate forming volcanoes and a trench |  | 16 |
| 6164464137 | Transform Fault | where plates slide past each other resulting in earthquakes |  | 17 |
| 6164464138 | what are the three plate movements? | Convergent, Divergent, and Transform | 18 | |
| 6164464139 | Fault Zone | large expanses of rock where movement has occurred |  | 19 |
| 6164464140 | Epicenter | the exact point on the surface of earth directly above the location where the rock raptures |  | 20 |
| 6164464141 | Richter Scale | a measure of the largest ground movement that occurs during an earthquake |  | 21 |
| 6164464142 | Tsunamis | are a large series of waves caused by sudden movement in the ocean floor |  | 22 |
| 6164464143 | Rock cycle | the constant formation and destruction of rocks |  | 23 |
| 6164464144 | Igneous Rock | Rocks that form directly from magma |  | 24 |
| 6164464145 | Sedimentary Rock | form when sediment such as mud, sand, or gravels are compressed by overlaying sediments |  | 25 |
| 6164464146 | Metamorphic Rocks | form when sedimentary, igneous or other rocks are subjected to high temperatures and pressure. |  | 26 |
| 6164464147 | Physical weathering | the mechanical breakdown of rocks and minerals |  | 27 |
| 6164464148 | Chemical weathering | the breakdown of rocks and minerals by chemical reactions | 28 | |
| 6164464149 | Erosion | the physical removal of rock fragments from a landscape or ecosystem |  | 29 |
| 6164464150 | Deposition | the accumulation of eroded material such as sediment, rock fragments or soil | 30 | |
| 6164464151 | Parent Material | what the soil is made from influences of soil formation (C Horizon) |  | 31 |
| 6164464152 | O Horizon | (organic layer) composed of the leaves, needles, twigs and animal bodies on the surface |  | 32 |
| 6164464153 | A Horizon | (topsoil) the zone of organic materials and minerals mixed together | | 33 |
| 6164464154 | B Horizon | (subsoil) composed primarily of inertial material with very little organic matter | | 34 |
| 6164464155 | C Horizon | (parent) the least weathered horizon and is similar to the parent material | | 35 |
| 6164464156 | strip mining | removing strips of soil and rock to expose ore |  | 36 |
| 6164464157 | Open pit mining | the creation of a large pit or hole in the ground that is visible from the surface |  | 37 |
| 6164464158 | Mountain top removal | removing the entire mountain top with explosives |  | 38 |
