Additional Information
Lava can reach temperatures of up to 1,300°C (2,400°F) and can flow at speeds of up to 100 km/h (62 mph). It is typically found in areas with volcanic activity, such as around volcanoes and fissures. Lava can also be found in areas where the Earth’s crust is thin, allowing magma to rise to the surface.
Lava is an important aspect of geology and has played a significant role in shaping the Earth’s surface over millions of years. It has created new landforms, changed the course of rivers, and buried entire cities.
Etymology
The word “lava” comes from the Latin “labes,” meaning “a fall” or “a slide,” which refers to the flowing motion of molten rock.
Usage Notes
Lava is often used in geological contexts to describe molten rock that flows from volcanoes or fissures. However, it can also be used more broadly to describe any type of molten material, such as molten metal or glass.
Cultural References
