EES 2.1
| Question | Answer |
|---|---|
| Earthquake | the sudden shaking of the ground caused by a rapid movement of rocks deep beneath the Earth's surface |
| fault line | a fracture in the Earth's crust where tectonic plates move past each other. |
| volcano | an opening in a planet's crust where molten rock, gases, and ash escape from beneath the surface |
| Pangea | the supercontinent |
| Seismograph | an instrument used to measure and record the motion of the Earth's surface during an earthquake or other seismic event |
| Alfred wegner | came up with the idea of pangea |
| Epicenter | were the earthquake starts |
| Density | having the component parts closely compacted together; crowded or compact |
| Kinetic energy | the energy of motion; it's the energy an object has because it is moving |
| divergent | different or deviating from a standard or a common point. It |
| Surface | the outside/ Uppermost part |
| Magnitude | the great size or extent of something. |
| Thermal | relating to heat. |
| Mantel | The Earth's mantle is a thick layer of dense, silicate rock located between the crust and the core |
| Continual drift | the theory that Earth's continents were once joined as a single supercontinent called Pangaea and have since moved to their current positions |
| seismic waves | vibrations that travel through Earth, generated by events like earthquakes, volcanic eruptions, and explosions |
| geosphere | the solid part of the Earth, extending from the crust down to the core |
| outer core | the outer part of the core |
| transform boundary | a type of plate boundary where two tectonic plates slide past each other horizontally |
| unstable isotopes | a version of an element with a nucleus that has too many or too few neutrons to be stable. |
| Earthquakes | when the tectonic plates spin |
| Richter scale | calculates an earthquake's magnitude (size) from the amplitude of the earthquake's largest seismic wave recorded by a seismograph |
| volcanosin | the process by which solids, liquids, and gases erupt from a planet's or moon's |
| sea floor spreading | the geological process where new oceanic crust is created at mid-ocean ridges and moves outward as tectonic plates diverge |
| support for Wegener’s proposed theory | Seafloor spreading provided the missing mechanism for Wegener's theory of continental drift by explaining how continents could move |
| Ridge | a long narrow hilltop, mountain range, or watershed. |
| isotope | form of a chemical element with the same number of protons but a different number of neutrons, leading to different atomic masses |
| Convection | the transfer of heat through the movement of a fluid (like air or water). |
| Asthenosphere | a partially molten, ductile layer in the Earth's upper mantle, located directly below the rigid lithosphere |
| Pangea | a prehistoric supercontinent that broke apart to form today's continents, |
| Fossil | he remains or impression of a prehistoric organism preserved in petrified form or as a mold or cast in rock. |
| Density | a measure of how much mass is contained in a given volume, calculated by dividing an object's mass by its volume |
| Divergent boundary | a tectonic plate boundary where two plates pull apart, creating new crust as magma rises to the surface |
| Subduction | the sideways and downward movement of the edge of a plate of the earth's crust into the mantle beneath another plate. |
| mantle convection | the slow movement of Earth's solid silicate mantle, driven by heat from the Earth's core that causes hotter, less dense material to rise and cooler, denser material to sink. |
| tsunamis | a series of extremely long waves caused by a large and sudden displacement of the ocean, most commonly from undersea earthquakes, but also from volcanic eruptions, landslides, and meteorite impacts. |
| Fault lines | fractures or zones of fractures in the Earth's crust where blocks of rock move past each other, caused by tectonic plate activity |
| Lava | molten rock that has erupted from a volcano onto the Earth's surface |
| Ductile | Can be drawn through wires |
| Magnitude | a general term for size, extent, or importance |
| Trenches | eep, long, and narrow depressions on the seafloor |
| Plume | a column or stream of a fluid (like air or water) carrying a pollutant or a thermal difference from a source |
| Half life | he time taken for the radioactivity of a specified isotope to fall to half its original value. |
| Thermal convection | the transfer of heat by the movement of fluids, which occurs when heated fluid rises and cooler fluid sinks, creating a circular flow. |
| Tectonic plates | massive, irregularly shaped slabs of rock that make up the Earth's outer layer (lithosphere) and move relative to one another atop the hotter, more mobile asthenosphere |
| Radioactivity | the spontaneous emission of energy from unstable atomic nuclei, which happens as they decay into a more stable state. |
| radioactive decay | the spontaneous process where unstable atomic nuclei release energy in the form of radiation to become more stable |
| Inner Core | the interior part of the core |
| convergent boundary | the spontaneous process where unstable atomic nuclei release energy in the form of radiation to become more stable |
| Rock Cycle | the continuous process by which rocks are created, destroyed, and changed from one form to another |
| Mountain formation | geological process driven by the movement of Earth's tectonic plates, which causes rocks to be pushed, folded, faulted, or uplifted |
| sismograph | an instrument used to measure and record ground vibrations from earthquakes, volcanic eruptions, and other seismic events |
