| 9638287807 | core | inner zone of the earth; it consists of a solid inner part and a liquid outer part | 0 | |
| 9638287808 | crust | solid outer zone of the earth; consists of an oceanic part and a continental part | 1 | |
| 9638287809 | igneous rock | rock formed when molten rock material (magma) wells up from the earth's interior, cools, and solidifies into rock masses | 2 | |
| 9638287810 | magma | molten rock below the earth's surface | 3 | |
| 9638287811 | mantle | zone of the earth's interior between its core and its crust; beneath asthenosphere; Comprises 80% of Earth's volume; Solid | 4 | |
| 9638287812 | metamorphic rock | rock produced when a preexisting rock is subjected to high temperatures (which may cause it to melt partially), high pressures, chemically active fluids, or a combination of these agents | 5 | |
| 9638287813 | mineral | any naturally occurring inorganic substance found in the earth's crust as a crystalline solid | 6 | |
| 9638287814 | rock | any material that makes up a large, natural, continuous part of the earth's crust | 7 | |
| 9638287815 | rock cycle | largest and slowest of the earth's cycles, consisting of geologic, physical, and chemical processes that form and modify rocks and soil in the earth's crust over millions of years | 8 | |
| 9638287816 | sedimentary rock | rock that forms from the accumulated products of erosion and in some cases from the compacted shells, skeletons, and other remains of dead organisms | 9 | |
| 9638287817 | sedimentation | *the process in which soil particles and decaying organic matter accumulate in layers on the ground or at the bottom of large bodies of water, contributing to the formation of sedimentary rock | 10 | |
| 9638287818 | tectonic plates | various-sized areas of the earth's lithosphere that move slowly around with the mantle's flowing asthenosphere; most earthquakes and volcanoes occur around the boundaries of these plates | 11 | |
| 9638287819 | tsunami | series of large waves generated when part of the ocean floor suddenly rises or drops, usually because of an earthquake | 12 | |
| 9638287820 | lava | *Magma that reaches Earth's surface | 13 | |
| 9638287821 | surface mining | removing soil, subsoil, and other strata and then extracting a mineral deposit found fairly close to the earth's surface; | 14 | |
| 9638287822 | overburden | layer of soil and rock overlying a mineral deposit | 15 | |
| 9638287823 | spoils, or mine tailings | unwanted rock and other waste materials produced when a material is removed from the earth's surface or subsurface by mining, dredging, quarrying, and excavation | 16 | |
| 9638287824 | open-pit mining | removing minerals such as gravel, sand, and metal ores by digging them out of the earth's surface and leaving an open pit behind | 17 | |
| 9638287825 | strip mining | form of surface mining in which bulldozers, power shovels, or stripping wheels remove large chunks of the earth's surface in strips | 18 | |
| 9638287826 | mountaintop removal | type of surface mining that uses explosives, massive shovels, and even larger machinery called draglines to remove the top of a mountain to expose seams of coal underneath a mountain | 19 | |
| 9638287827 | smelting | process in which a desired metal is separated from the other elements in an ore mineral | 20 | |
| 9638287828 | subsurface mining | consists of digging tunnels or shafts into the earth to reach buried ore deposits | 21 |
