| 12460931232 | Geology | Study of the earth's dynamic history. Geologists study and analyze rocks and the features and processes of the earth's interior and surface. | 0 | |
| 12460931233 | Core | Inner zone of the Earth. It consists of a solid inner core and a liquid outer core. | 1 | |
| 12460931234 | Mantle | Zone of the earth's interior between its core and its crust | 2 | |
| 12460931235 | Crust | Solid outer zone of the earth. It consists of oceanic and continental crust. | 3 | |
| 12460931236 | Tectonic Plate | 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. | 4 | |
| 12460931237 | Lithosphere | Outer shell of the earth, composed of the crust and the rigid, outer most part of the mantle outside the asthenosphere. material found in the earth's plates. | 5 | |
| 12460931238 | Divergent Plate | Area where the earth's lithospheric plates move in apart in opposite directions | 6 | |
| 12460931239 | Convergent Plate | Area where the earth's lithospheric plates are pushed together | 7 | |
| 12460931240 | Transform Fault | Area where the earth's lithospheric plates move in opposite but parallel directions along a fracture (fault) in the lithosphere | 8 | |
| 12460931241 | Weathering | Physical and chemical processes in which solid rock exposed at earth's surface is changed to separate solid particles and dissolved material, which can then be moved to another place as sediment | 9 | |
| 12460931242 | 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 | 10 | |
| 12460931243 | Mineral Resource | Concentration of naturally occurring solid, liquid, or gaseous material in or on the earth's crust in a form and amount such that extracting and converting it into useful material or items is currently or potentially profitable. Mineral resources are classified as metallic or nonmetallic. | 11 | |
| 12460931244 | Ore | Part of a metal-yielding material that can be economically extracted from a mineral; typically containing two parts: the ore mineral, which contains the desired metal, and waste mineral material. | 12 | |
| 12460931245 | High Grade Ore | Ore containing a large amount of the desired mineral. | 13 | |
| 12460931246 | Low Grade Ore | Ore containing a small amount of a desired mineral | 14 | |
| 12460931247 | Surface Mining | Removing soil, subsoil, and other strata and then extracting a mineral deposit found fairly close to the earth's surface | 15 | |
| 12460931248 | Subsurface Mining | Extraction of a metal ore or fuel resource such as coal from a deep underground deposit. | 16 | |
| 12460931249 | Overburden | Layer of soil and rock overlying a mineral deposit. Surface mining removes this layer. | 17 | |
| 12460931250 | Spoils | Unwanted rock and other waste materials produced when a material is removed from the earth's surface or subsurface by mining, dredging, quarrying, or excavation. | 18 | |
| 12460931251 | 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. | 19 | |
| 12460931252 | Area Strip Mining | Form of surface mining in which bulldozers, power shovels, or stripping wheels remove large chunks of the earth's surface in strips. | 20 | |
| 12460931253 | Contour Strip Mining | Form of surface mining used on hilly or mountainous terrain. A power shovel cuts a series of terraces into the side of a hill. An earth mover removes the overburden, and a power shovel extracts the coal. The overburden from each new terrace is dumped onto the one below. | 21 | |
| 12460931254 | Mountain Top Removal | Type of surface mining that uses explosives, massive shovels, and large machines called drag lines to remove the top of a mountain to expose seams of coal underneath a mountain. | 22 | |
| 12460931255 | Acid Mine Drainage | Occurs when rainwater seeping through a mine or mine waste pile carries sulfuric acid to nearby streams and groundwater. | 23 | |
| 12460931256 | Depletion Time | The time it takes to use a certain fraction (usually 80%) of the known or estimated supply of a nonrenewable resource at an assumed rate of use. Finding and extracting the remaining 20% usually costs more than it is worth. | 24 | |
| 12460937593 | tailings (mining spoils) | unwanted waste material created during mining | 25 | |
| 12460960694 | Asthenosphere | The soft layer of the mantle on which the tectonic plates move | 26 | |
| 12460973854 | Graphene | Nanotech-This is a single layer of graphite. They have interlocking hexagonal rings of carbon, one atom thick, so therefore very thin. Excellent electrical conductivity, and is used in electronics and computer chips. | 27 | |
| 12461036301 | phosphorene | single layer of black phosphorus atoms, semiconductor, nanotech | 28 | |
| 12461051711 | Tsunami | a long high sea wave caused by an earthquake, submarine landslide, or other disturbance. | 29 | |
| 12461057920 | earthquake | The shaking that results from the movement of rock beneath Earth's surface. | 30 | |
| 12461068216 | Volcanoes | an opening in the Earth's crust through which molten lava, ash, and gases are ejected, resulting in creation and destruction | 31 |
