Volcanic rock

Volcanic rock (often shortened to volcanics in scientific contexts) is a rock formed from lava erupted from a volcano other words, it differs from other igneous rock by being of volcanic origin. Like all rock types, the concept of volcanic rock is artificial, and in nature volcanic rocks grade into hypabyssal and metamorphic rocks and constitute an important element of some sediments and ...

Understanding highly explosive basaltic eruptions ...

 · Basaltic scoria cone volcanoes are the most abundant volcanic landform on Earth and occur in all tectonic settings. Basaltic magmas have lower viscosities, higher temperatures, and lower volatile contents than silicic magmas, and therefore generally have a lower potential for explosive activity. However, basaltic eruptions display great variability, from mild lava flows to more energetic ...

Plinian eruption

Plinian eruptions or Vesuvian eruptions are volcanic eruptions marked by their similarity to the eruption of Mount Vesuvius in 79 AD, which destroyed the ancient Roman cities of Herculaneum and Pompeii.The eruption was described in a letter written by Pliny the Younger, after the death of his uncle Pliny the Elder.. Plinian/Vesuvian eruptions are marked by columns of volcanic debris and hot ...

Science

Volcanic blocks are tephra ejected from a vent during explosive eruptions. Basalt, which makes up shield volcanoes, does not usually erupt explosively. Explain the relationship between the viscosity of a magma and its temperature. The hotter the magma, the lower the viscosity. Hot magma flows quickly; cooler magma flows more slowly.

Is basalt stone porous?

 · 4.4/5 (326 Views . 27 Votes) All natural stones are porous to some extent, which means they may absorb liquids and moisture if exposed.
