volcanos and plating
| Question | Answer |
|---|---|
| earthquake | the sudden, rapid shaking of the ground caused by the release of energy in the Earth’s lithosphere, usually due to the abrupt slipping of rock masses along a fault plane |
| fault | a fracture or zone of fractures in the Earth’s crust along which two blocks of rock have moved relative to each other |
| seismic wave | vibrations of elastic energy that travel through the Earth's interior or along its surface, primarily caused by earthquakes, volcanic eruptions, magma movement, landslides, or man-made explosions |
| focus | the exact point within the Earth's crust or mantle where an earthquake's rupture begins and energy is first released |
| epicenter | he underground location where an earthquake rupture initiates. It is typically the area of greatest intensity |
| volcano | an opening in a planet's crust that allows hot, molten rock (magma), ash, and gases from the interior to escape, |
| hot spot | a stationary, exceptionally hot plume of magma rising from deep within the Earth's mantle, which melts through the tectonic plate above to form volcanoes |
