| Term | Definition |
|---|---|
| Earthquake | the sudden shaking or trembling of the Earth's crust caused by the release of energy when underground rock shifts along a fault |
| Fault lines | a fracture or zone of fractures in the Earth's crust where tectonic plates meet, allowing for their movement and displacement |
| volcanoes | a fracture or zone of fractures in the Earth's crust where tectonic plates meet, allowing for their movement and displacement |
| Thermal energy | the internal energy of a system caused by the total kinetic energy of its constantly moving atoms and molecules |
| Asthenosphere | asthenosphere definition earth and environmental science |
| Geosphere | the solid part of Earth, encompassing the crust, mantle, and core, and includes all rocks, minerals, and landforms |
| Siesmograph | an instrument that measures and records details of earthquakes, such as force and duration. |
| Richter scale | The Richter scale is a numerical scale for measuring the magnitude, or "strength," of an earthquake |
| Continental crust | is the thick, less dense layer of the Earth's crust that forms the continents and their shelves, composed mainly of granitic rocks |
| Pangea | supercontinent existed from the late Paleozoic to the early Mesozoic era, which combined all of Earth's landmasses into one |
| Alfred Wegener | German meteorologist, geophysicist, and polar researcher best known for proposing the theory of continental drift in 1912 |
| Fossils | the remains or impression of a prehistoric organism preserved in petrified form or as a mold or cast in rock. |
| Continental drift | the theory that Earth's continents have moved across the planet's surface over geological time, originating from pangea |
| Oceanic crust | the Earth's thin, dense outer layer that forms the ocean floor |
| Divergent | where two plates are moving away from each other, resulting in the creation of new crust as magma rises to fill the gap |
| Lava | hot molten or semifluid rock erupted from a volcano or fissure, or solid rock resulting from cooling of this. |
| Magma | hot fluid or semifluid material below or within the earth's crust from which lava and other igneous rock is formed on cooling. |
| Epicenter | the point on the earth's surface vertically above the focus of an earthquake. |
| Magnitude | a quantitative measure of the size of an earthquake at its source, reflecting the amount of energy released by the fault rupture |
| Natural disasters | a catastrophic event caused by natural processes of the Earth that results in significant destruction, disruption |
