Earth structures
| Question | Answer |
|---|---|
| mineral | A natural, usually inorganic solid that has a characteristic chemical composition and an orderly internal structure. |
| element | A substance that cannot be separated or broken down into simpler substances by chemical means; all atoms of an element .have the same atomic number. |
| atom | The smallest unit of an element that maintains the properties of that element. |
| compound | A substance made up of atoms or ions of two or more different elements joined by chemical bonds. |
| matter | Anything that has mass and takes up space. |
| crystal | Natural solid substance that has a definite geometric shape. |
| streak | The color of a mineral in powdered from. |
| luster | The way in which a mineral reflects light. |
| cleavage | In geology, the tendency of a mineral to split along specific planes of weakness to from smooth, flat surfaces. |
| weathering | The natural process by which atmospheric agents, such as wind, rain, and temperature changes, disintegrate and decompose. |
| erosion | The process by which wind, water, ice, or gravity transports soil and sediment from one location to another. |
| deposition | the process in which material is laid down.(Earth science) The change of state from a gas directly to a solid. (physical science) |
| igneous rock | Rock that forms when magma cools and solidifies. |
| sedimentary rock | A rock forms from compressed or cemented layers of sediment. |
| metamorphic rock | A rock that forms from other rocks as a result of intense heat, pressure, or chemical processes. |
| rock cycle | The series of processes in which rock forms, changes from one type to another, is destroyed, and forms again by geologic processes. |
| uplift | The rising of regions of the Earth's crust to higher elevations. |
| subsidence | The rising of regions of the Earth's crust to lower elevations. |
| rift zone | a linear area of weakness in the Earth's crust or a volcano where tectonic plates or volcanic flanks are pulling apart |
| crust | a hard surface layer (as of soil or snow) |
| mantle | a loose, sleeveless cloak or cape, but commonly refers to a covering layer (e.g., "a mantle of snow") or the geological layer of Earth between the crust and core |
| convection | the transfer of heat through the movement of fluids (liquids or gases) as warmer, less dense material rises and cooler, denser material sinks, creating circulating convection currents that distribute thermal energy |
| core | a pivotal, interracial civil rights organization that pioneered nonviolent direct action, including sit-ins and the 1961 Freedom Rides |
| lithosphere | Earth's rigid, rocky outer layer, composed of the crust and the solid, uppermost part of the mantle, extending about 60-100 miles deep, and is broken into tectonic plates that move, causing earthquakes, mountain building, and volcanoes |
| asthenosphere | a hot, ductile, and plastic-like region of the upper mantle located directly below the rigid lithosphere, typically 80 to 700 km deep |
| mesosphere | the third layer of Earth's atmosphere, situated between the stratosphere and the thermosphere |
| pangea | all the Earth |
| sea-floor spreading | a geological process where tectonic plates diverge at mid-ocean ridges, causing magma to rise from the mantle, cool, and create new oceanic crust |
| plate tectonics | a scientific theory that explains how major landforms are created as a result of Earth's subterranean movements |
| tectonic plates | a massive, irregularly shaped slab of solid rock, composed of both continental and oceanic lithosphere |
| convergent boundary | a massive, irregularly shaped slab of solid rock, composed of both continental and oceanic lithosphere |
| divergent boundary | a tectonic boundary where two plates move away from each other, causing tensional stress that breaks the lithosphere |
| transform boundary | a geological zone where two tectonic plates slide horizontally past one another, neither creating nor destroying the Earth's crust |
| deformation | the alteration, distortion, or change in the shape, size, or structure of an object, typically caused by applied stress, force, or, in medical contexts, extrinsic pressure on developing tissue |
| folding | bending, doubling, or covering one part of an object over another to make it more compact |
| fault | occurs when the material or fluid's adjacent layers move relative to each other due to an applied force |
| shear stress | a force applied parallel to a material's surface, causing internal layers to slide past one another rather than pulling apart or compressing |
| tension | a state of being stretched tight (physical), mental/emotional strain (stress), or underlying hostility between groups |
| compression | the act, process, or result of pressing, squeezing, or packing something into a smaller space, volume, or duration |
| earthquake | the sudden, rapid shaking of the ground caused by the release of built-up stress along fault lines in the Earth's crust, often resulting from the movement of tectonic plates |
| focus | directing attention, efforts, or energy toward a specific goal, task, or object,, often requiring the exclusion of distractions |
| epicenter | the exact point on the Earth's surface directly above where an earthquake or underground explosion originates |
| tectonic plate boundary | the edge or zone where two or more of Earth's rigid lithospheric plates meet and interact |
| elastic rebound | what happens to the crustal material on either side of a fault during an earthquake |
| volcano | an opening on the surface of a planet or moon that allows material warmer than its surroundings to escape from its interio |
| magma | molten rock that is underground |
| lava | molten rock that issues from a volcano or from a fissure in the surface of a planet (such as earth) or moon |
| vent | an opening for the escape of a gas or liquid or for the relief of pressure |
| hot spot | a dish of soup/stock kept simmering in a pot by a heat source on the table, accompanied by an array of raw meats, vegetables and soy-based foods which diners quickly cook by dipping in broth |
