Obsidian, is a glass gemstone which is created in the fiery depths of a volcano, they surface during an eruption.
eventually it cools and turns into an Igneous rock formation.
Intrusive igneous rocks are thusly formed.
When lava cools down quickly at the surface of the Earth, it forms an igneous rock called basalt. Basalt is dark in color, fine-grained, and contains minerals such as olivine and pyroxene.
the type of rock formed when lava or magma cools is igneous rock..
No, igneous rocks are formed from molten rock (Lava, or Magma).

Igneous rocks are formed when lava cools. After a eruption, the lava cools, and the igneous rock is formed.

When lava cools down quickly at the surface of the Earth, it forms an igneous rock called basalt. Basalt is dark in color, fine-grained, and contains minerals such as olivine and pyroxene.
Igneous rock is formed from solidified and cooled magma or lava.
Igneous rock is formed from lava that has cooled and, of course, hardened.
the type of rock formed when lava or magma cools is igneous rock..
volcanic rocks formed from different processes. Pumice is a light and porous rock formed from foamy lava, obsidian is a dark volcanic glass formed from quickly cooled lava, and scoria is a dark, vesicular rock formed from gas-rich lava.
Igneous rock, specifically extrusive or volcanic rock, is formed when lava cools and hardens. This type of rock typically has small crystals due to the rapid cooling process and examples include basalt and rhyolite.
Igneous rock is formed when lava or magma cools.
No, igneous rocks are formed from molten rock (Lava, or Magma).
