| Asthenosphere | the somewhat fluid portion of the mantle upon which the lithosphere is located |
| Cementation | process of binding and hardening sediments into hard rock |
| Compaction | process by which overlying pressure from rocks and soil reduces the size or volume of sediments |
| Compositional layers | – structural layers of Earth defined by the materials from which they are made |
| Core | the central region of the Earth; primarily made of nickel and iron |
| Igneous | a type of rock formed when crystallized through melting and cooling rock |
| Lithosphere | the solid and rigid outer layer of the Earth consisting of the crust and the solid portion of the upper mantle; positioned between the atmosphere and the asthenosphere |
| Mantle | the region inside the Earth between the core and the crust |
| Mechanical Layers | structural layers of Earth defined on the basis of how materials act |
| Mesosphere | the region of the Earth’s atmosphere between the stratosphere and thermosphere (30-50 miles in altitude) |
| Metamorphic | a type of rock formed when igneous or sedimentary rocks are put under intense heat and / or pressure in the Earth’s crust |
| Plasticity | the quality of being easily shaped or molded |
| Rock Cycle | the continual process by which rocks can be changed into different types of rock |
| Sedimentary | a type of rock formed through the accumulation, compaction, and cementation of sediment |
| Sedimentation | the deposition of solid material from being suspended in a fluid (water |
| Semi-solid | having the qualities of both a solid and a liquid; exceptionally thick substance |
